        "content": "Hi! The Fiio DM13 doesn\u2019t use regular removable batteries like AA/AAA \u2014 it has a built-in rechargeable lithium battery. Here\u2019s exactly what it uses, where it is, and how you charge it:\n\n---\n\n### \ud83d\udd0b What Kind of Battery\n\n- It\u2019s a **3750 mAh**, **3.8 V** cobalt lithium-ion battery. ([fiio.com](https://fiio.com/dm13?utm_source=openai))  \n- It\u2019s internal \u2014 you don\u2019t insert a battery, it comes already installed inside the unit. ([head-fi.org](https://www.head-fi.org/showcase/fiio-dm13.27765/?utm_source=openai))  \n\n---\n\n### \ud83d\udccd Where It Is\n\n- The battery is housed **inside the main body** of the DM13. You\u2019ll typically find its compartment sealed, not accessible without opening the device (which usually voids warranty).  \n- It\u2019s not something you can swap out regularly like AA batteries; repair or replacement usually means sending it in or having a technician open it. This is common with modern built-in battery devices.  \n\n---\n\n### \u26a1 How to Charge & Use Power\n\n- Use a **Type-C USB cable** with a **5 V / 2 A power adapter**. That\u2019s the recommended safe power input. ([fiio.com](https://fiio.com/dm13?utm_source=openai))  \n- There are two USB-C ports: one labeled **POWER IN** (for charging or powering the device) and another labeled **USB REC** (for ripping CDs or recording, which can also be used with power in some modes). ([m.media-amazon.com](https://m.media-amazon.com/images/I/81gkVUxgtLL.pdf?utm_source=openai))  \n\n---\n\n### \ud83d\udd0d How to See Battery Level\n\n- Turn on the device. Then **short press the power button** (that\u2019s the first button) to show battery status on the screen. It will display:\n  - **BAT5** = full\n  - **BAT4** = ~ 80-90%\n  - **BAT3** = ~ 60-80%\n  - **BAT2** = ~ 40-60%\n  - **BAT1** = ~ 20-40%\n  - **BAT0** = low, needs charging ([fiio.com](https://www.fiio.com/newsinfo/963178.html?utm_source=openai))  \n\n---\n\nIf you want help opening the unit safely (for repair or replacement), I can guide you through that too \u2014 just shout!"

([fiio.com](https://www.fiio.com/newsinfo/974467.html?utm_source=openai)) <br> - When in USB OUT mode, if the DM13 is powered *through this port*, the **USB REC** port may be used to connect a computer for recording usage. ([m.media-amazon.com](https://m.media-amazon.com/images/I/81gkVUxgtLL.pdf?utm_source=openai)) |\n| **USB REC**  | \u201cUSB REC\u201d or \u201cUSB RECORD\u201d | - Main use: connect this port to a computer or device to record CDs or rip tracks. The data travels out this port. ([fiio.com](https://www.fiio.com/newsinfo/974467.html?utm_source=openai)) <br> - It can also accept power (i.e. supply 5 V) \u2014 so you *can* charge through USB REC. But rip/record features only work when in \u201cUSB OUT\u201d mode. ([m.media-amazon.com](https://m.media-amazon.com/images/I/81gkVUxgtLL.pdf?utm_source=openai)) |\n\n---\n\n## \ud83d\udd79\ufe0f Switches on the Back\n\nThere are two \u201ctoggle\u201d switches. They are small and probably labeled \u201cD.MODE\u201d and \u201cESP.\u201d Knowing where they are is helpful, plus how each works.\n\n| Switch     | Label        | What It Does                                                                                              |\n|-------------|----------------|-----------------------------------------------------------------------------------------------------------|\n| **D.MODE**   | \u201cDesktop Mode\u201d | When set to **ON**, the DM13 runs directly off USB power without using the battery (when plugged in). Battery still charges when connected. <br> When set to **OFF**, it uses battery and charges as usual. <br> Useful when you\u2019re stationary and plugged in long-term. ([fiio.com](https://www.fiio.com/newsinfo/974467.html?utm_source=openai)) |\n| **ESP**      | \u201cESP switch\u201d | Stands for *Electronic Shock Protection*. <br> When ON \u2192 adds buffering so music won\u2019t skip when the player is jostled or bumped (especially while reading CDs). <br> When OFF \u2192 may reduce latency and slightly improve sound, but more risk of skipping during movement. ([fiio.com](https://www.fiio.com/newsinfo/974467.html?utm_source=openai)) |\n\n---\n\n## \ud83d\udccd How to Tell by Touch / Labels\n\n- The **USB ports** are clearly labeled: one says *POWER IN*, the other *USB REC*. You can feel and read these just above or below each port. ([fiio.com](https://www.fiio.com/newsinfo/974467.html?utm_source=openai))  \n- The **switches**:\n  - **D.MODE** is the Desktop Mode switch.\n  - **ESP** is the shock protection toggle.\n  - They\u2019re usually side-by-side, or close together, often slightly offset from the row of ports so you can feel them separately. ([fiio.com](https://www.fiio.com/newsinfo/963171.html?utm_source=openai))\n\n---\n\nIf you want, I can help you with a tactile guide\u2014where to feel for each label, in what order\u2014to make finding these in the dark easier.

        "content": "Here\u2019s a tactile guide to help you tell the ports and switches apart by feel on the *back* of your Fiio DM13\u2014based on your layout (\u201cfar right two headphone jacks, then USB-C, switch, USB-C, last switch\u201d). I\u2019ll match what you feel to how the manual describes them.  \n\n---\n\n## \ud83e\udded What You Feel (Left \u2192 Right on the Back Panel, from the far right switches towards the ports)\n\nBased on how you described the layout, when facing the **back** (the side opposite the disc lid):\n\n\u00d7 \u201cfar right there is two hole-like headphone jacks\u201d \u2192 those are probably the **line outputs** labeled \u201cBAL.LO\u201d and \u201cLO/COAX/OPT\u201d.  \n\u00d7 Then a **USB-C port**, then a **switch**, then another **USB-C** port, and then the **last switch**.  \n\nSo physically from right-most to left, it likely goes:\n\n1. Two hole-like jacks \u2014 4.4 mm balanced LO (\u201cBAL.LO\u201d) and shared 3.5 mm LO/Coax/Optical (\u201cLO/COAX/OPT\u201d). ([manuals.plus](https://manuals.plus/asin/B0DKXDKBG5?utm_source=openai))  \n2. USB-C port \u2014 either *POWER IN* or *USB REC*.  \n3. Switch \u2014 either *ESP* or *D.MODE*.  \n4. USB-C port \u2014 the other of *POWER IN* / *USB REC*.  \n5. Last switch \u2014 whichever is left (ESP or D.MODE).  \n\n---\n\n## \ud83d\udd0d What Each Port & Switch Actually Is\n\nHere\u2019s what each is, how it works, and how to distinguish them by label (feel/look) or by function.\n\n| Component | Label (what you can feel/see) | Function | How to Tell by Touch / Use |\n|------------|----------------------------------|-----------|-------------------------------|\n| **Two jacks (hole-like)** | One will feel wider/ thicker (4.4 mm) and one thinner (3.5 mm); might be labeled \u201cBAL.LO\u201d (4.4mm) and \u201cLO/COAX/OPT\u201d (3.5mm three-in-one) | Used for outputting sound or digital signals: *BAL.LO* is balanced line out. *LO/COAX/OPT* is shared for 3.5 mm analog line out or coaxial/optical digital output. ([fiio.com](https://www.fiio.com/dm13_parameters?utm_source=openai)) | Feel the difference in hole sizes. 4.4 mm is noticeably bigger. If you need optical/coaxial digital signal, that small (3.5 mm) shared jack is where it is. |\n| **USB-C port #1** (first one after the jacks) | One of them will be labeled \u201cPOWER IN\u201d or \u201cUSB REC\u201d (often printed above or below) | *POWER IN* is for charging or providing power. *USB REC* is for recording/ripping CDs to a computer or USB drive. ([fiio.com](https://www.fiio.com/dm13_parameters?utm_source=openai)) | Check the small text near the port. Plug in correctly to charge (POWER IN) or to record (USB REC) depending on the mode. If you're holding cord, try each one to see which mode changes. |\n| **Switch #1 (middle back)** | Likely one of the two toggles. One will be labeled \u201cESP\u201d (electronic shock protection) and one \u201cD.MODE\u201d (Desktop Mode). | The ESP switch:\n ON = enable buffer to help prevent skipping when moving; OFF = less lag, better sound quality in still use. \n The D.MODE switch:\n ON = Desktop Mode enabled; the device runs directly from USB power without draining battery.\n OFF = device uses and charges battery normally. ([fiio.com](https://www.fiio.com/newsinfo/974467.html?utm_source=openai)) | The text near the switch will show \u201cESP\u201d or \u201cD.MODE\u201d. Also feel: ESP switch is often nearer the line-out jacks; D.MODE often nearer one of the USB-C ports. You can try flipping them and observing what the display shows (it\u2019ll say when ESP is on or when Desktop Mode is on). |\n| **USB-C port #2** (after the first switch) | The second USB-C, with the other of the two labels (\u201cUSB REC\u201d / \u201cPOWER IN\u201d) | Same functions as port #1, but swapped. Depending on which port is powered and what mode the player is in, these behave slightly differently. ([m.media-amazon.com](https://m.media-amazon.com/images/I/81gkVUxgtLL.pdf?utm_source=openai)) | If you plug into one and nothing seems to happen, try the other. The manual says both can charge. But only one works for connecting to computer for recording depending on mode (USB OUT mode). |\n| **Switch #2 (leftmost switch in that group)** | The last switch on that row; whichever spelling you see (\u201cESP\u201d or \u201cD.MODE\u201d)\u2014the other one. | Either enables/disables ESP or toggles Desktop Mode depending on which switch it is. | Same tactile cues: label and small physical toggle. Observe what happens: when D.MODE is ON, battery isn\u2019t used (if plugged into an adapter). When ESP is ON and the device is bumped, skipping is less likely\u2014but sound may change slightly. |\n\n---\n\n## \u2699\ufe0f Example Based on Your Description\n\nAccording to what you said:\n\n- \u201cFar right there is two hole-like headphone jacks\u201d \u2192 these are the output jacks (BAL.LO + LO/COAX/OPT).\n- Then \u201cUSB-C\u201d \u2192 likely *POWER IN* or *USB REC*.\n- Then \u201ca switch\u201d \u2192 likely *ESP* if it\u2019s closer to the jacks, or *D.MODE* depending on spacing.\n- Then \u201canother USB-C\u201d \u2192 the other USB port.\n- Then \u201cthe last switch\u201d \u2192 the one you didn\u2019t hit yet of *ESP* or *D.MODE*.\n\nSo you can map them out by moving your fingers from rightmost to left:\n\n1. Touch the two jacks \u2014 feel sizes.  \n2. Find the first USB-C \u2014 read the label.  \n3. Next toggle \u2014 read \u201cESP\u201d or \u201cD.MODE.\u201d  \n4. Next USB-C \u2014 the other port.  \n5. Last toggle \u2014 the remaining function.\n\n---\n\nIf you like, I can send you a **braille-friendly** label map (what label goes where) that you could mark on a protector or case so you feel each part correctly."

It\u2019s \u201cLO/COAX/OPT,\u201d meaning it\u2019s analog line-out OR for coaxial or optical digital output. ([fiio.com](https://www.fiio.com/newsinfo/974467.html?utm_source=openai))  \n3. **USB-C port marked \u201cPOWER IN\u201d** \u2014 one of the two USB-C connectors. This is used for charging, power input, or for track ripping when you plug in a USB flash drive to this port. ([fiio.com](https://www.fiio.com/newsinfo/974467.html?utm_source=openai))  \n4. **Switch labelled \u201cESP\u201d** \u2014 the \u201cElectronic Shock Protection\u201d switch. Toggle it ON to enable skip protection (buffering) so CDs don\u2019t skip when moving; OFF if you prefer the best sound and are listening in stable conditions. ([fiio.com](https://www.fiio.com/newsinfo/974467.html?utm_source=openai))  \n5. **USB-C port marked \u201cUSB REC\u201d (USB Record)** \u2014 the second USB-C. This is for computer recording/ripping such as sending CD data to a computer. It also can accept power, depending on mode. ([fiio.com](https://www.fiio.com/newsinfo/974467.html?utm_source=openai))  \n6. **Switch labelled \u201cD.MODE\u201d (Desktop Mode)** \u2014 last one. Turn it ON to bypass battery and run directly off USB power (if plugged in), useful when you\u2019re stationary. OFF to use battery normally. ([fiio.com](https://www.fiio.com/newsinfo/974467.html?utm_source=openai))  \n\n---\n\nSo in your description:\n\n- The **first switch** (after the first USB-C port) is **ESP**.  \n- The **last switch** (after the second USB-C port) is **D.MODE**.  \n\nIf you want, I can lay this out as a diagram you could touch / mark on a case so you don\u2019t need to see it."

Once it's on and playing or ready, **short-press** the Power button. This will switch its mode.  \n3.

Here\u2019s what you need to know:\n\n---\n\n## \u2705 What \u201cMP3 disc\u201d means for the DM13\n\n- The player supports **CD-R** discs that have MP3 (and other audio formats like FLAC, WAV, WMA) files written to them. That\u2019s commonly called an \u201cMP3 disc\u201d. ([fiio.com](https://www.fiio.com/newsinfo/974465.html?utm_source=openai))  \n- It does *not* support playing SACD-only discs, but if the disc has a CD audio layer (as some hybrid SACDs do), then those traditional CD tracks can be played. ([fiio.jp](https://www.fiio.jp/support/dm13bt/?utm_source=openai))\n\n---\n\n## \ud83d\udd27 Important guidelines for burning MP3 CDs that will work\n\nTo ensure your MP3 disc works in the DM13, follow these tips:\n\n- **Burn using CD-R format** \u2014 DM13 plays MP3 from CD-R (not always guaranteed with CD-RW depending on burn quality). ([fiio.com](https://www.fiio.com/newsinfo/974465.html?utm_source=openai))  \n- **File system & disc structure** \u2014 MP3 files need to be organized in a standard folder and file structure. Avoid overly nested folders; some reports suggest the \u201cNext Track\u201d button must be pressed many times if tracks are deeply nested. ([reddit.com](https://www.reddit.com/r/FiiO/comments/1tqwqfk/fiio_dm13_is_it_possible_to_skip_folders_on_an/?utm_source=openai))  \n- **Check burner quality & speed** \u2014 Slower burn speeds and good quality \u201cblank\u201d discs help improve compatibility. Discs burned at very high speeds sometimes don\u2019t read well.  \n- **Use correct bitrates/formats** \u2014 MP3 files should be in standard MP3 format. Avoid exotic or variable formats if possible.  \n\n---\n\nIf you like, I can walk you through step-by-step how to burn an MP3 CD properly (settings, software, speed, etc.) so your DM13 can read it easily."

([fiio.com](https://www.fiio.com/newsinfo/974467.html?utm_source=openai))  \n\nSo when you run your finger along the top from the left, it goes:  \n1. Power \u2192 2. Play/Pause \u2192 3. Previous Track \u2192 4. Next Track \u2192 5. Volume Down \u2192 6. Volume Up \u2192 7. Playback Mode/Function Button.

Feel which side is the front of the player (usually the displays and headphone jacks are on the front edge).\n2. Move your finger to the top panel, then slide over to the **second** button from the left.\n3. Press that button **once (short press)**. It should trigger the CD to play. If the disc is already spinning and the display shows track info, this will start playback. ([manuals.plus](https://manuals.plus/asin/B0DK5996CS?utm_source=openai))  \n\n---\n\nIf after pressing that, it still doesn\u2019t play:\n\n- Check you\u2019re in the correct **output mode**, typically \u201cPRE OUT\u201d, by pressing the Power button briefly and verifying the screen.

Here\u2019s a breakdown to help you understand and set it up the way you want.\n\n---\n\n### \ud83d\udd01 Modes and what matters\n\nThe DM13 has several output modes:\n\n- **PRE OUT** \u2014 for analog output via headphone/speaker ports.  \n- **USB OUT** \u2014 for ripping tracks or output to a computer.  \n- **SPDIF OUT** \u2014 for digital coaxial/optical output.  \n- **BLUE OUT** \u2014 Bluetooth transmission mode. ([fiio.com](https://www.fiio.com/newsinfo/974467.html?utm_source=openai))\n\nYou cycle through these modes by **short pressing the Power button** when the device is on. ([fiio.com](https://www.fiio.com/newsinfo/974467.html?utm_source=openai))\n\n---\n\n### \u2753 Do you need to go to Bluetooth mode every time?\n\n- Yes \u2014 if your device is *not* already in Bluetooth mode when you turn it on, you\u2019ll need to manually switch to **BLUE OUT** via the Power button. It does **not** automatically detect that you want Bluetooth just because you turned it on. ([fiio.com](https://www.fiio.com/newsinfo/974467.html?utm_source=openai))  \n- Once in **BLUE OUT**, long-pressing the previous-track button puts the device in pairing mode (if it isn\u2019t already paired).

Let\u2019s go through a checklist to narrow down what might be wrong and how to fix it.\n\n---\n\n## \u2705 Troubleshooting Steps\n\n| Step | What to check | Why it matters |\n|---|---|----------------|\n| 1. Power on & mode | Make sure the device is turned on, not just connected to power. Then press the **Power** button briefly (short press) until it shows **PRE OUT** mode. ([fiiosupport.freshdesk.com](https://fiiosupport.freshdesk.com/support/solutions/articles/69000869724-how-to-use-dm13-local-playback-function-?utm_source=openai)) |\n| 2. Insert a CD correctly | Slide the **Eject** button to open the lid, place the CD flat, close it firmly. Look for spinning or display \u201ctrack 1\u201d info. If it shows \u201cNo Disc,\u201d it may be misaligned or dirty. ([reddit.com](https://www.reddit.com/r/FiiO/comments/1qbhwm0/fiio_dm13_cd_player_no_disc_wont_play_cd/?utm_source=openai)) |\n| 3. Press Play/Pause | Press the **Play/Pause** button once after disc insertion and mode set. Some firmware (like V27 or V16) requires this, because autoplay was changed. ([fiio.com](https://www.fiio.com/newsinfo/1050360.html?utm_source=openai)) |\n| 4. Check the volume level | Like many players, if the volume is near the bottom, you may not hear anything. Use the Volume Up button (short presses) to bring it up. ([fiio.com](https://www.fiio.com/newsinfo/974467.html?utm_source=openai)) |\n| 5. Confirm headphone/speaker connection | Make sure your output such as 3.5 mm or 4.4 mm headphones are plugged in correctly. Also ensure the cable or speakers are working. |\n| 6. Output mode & firmware | If output is set to something like SPDIF or BLUE OUT but you're using wired headphones, you\u2019ll hear nothing on the PO outputs. It needs to be on **PRE OUT** for headphone/speaker connected via analog ports. ([fiiosupport.freshdesk.com](https://fiiosupport.freshdesk.com/support/solutions/articles/69000869724-how-to-use-dm13-local-playback-function-?utm_source=openai)) |\n\n---\n\n## \u26a0\ufe0f Common Issues That Match \u201cNothing Happens\u201d\n\n- **Volume extremely low** \u2014 maybe set at minimum without realizing. Try raising it significantly.  \n- **Wrong output mode** \u2014 e.g., it\u2019s on Bluetooth or digital output (SPDIF/USB OUT). If you're using headphones via the analog PO/LO ports, you need **PRE OUT**. ([fiiosupport.freshdesk.com](https://fiiosupport.freshdesk.com/support/solutions/articles/69000869724-how-to-use-dm13-local-playback-function-?utm_source=openai))  \n- **Firmware changed behavior** \u2014 since the firmware versions V27 (BT) or V16 (non-BT), the device was updated so that after inserting or closing the lid, you must *manually* press Play/Pause. Autoplay was removed. ([fiio.com](https://www.fiio.com/newsinfo/1050360.html?utm_source=openai))  \n- **\u201cNo disc\u201d or \u201creading\u201d display** but nothing plays \u2014 could be that the disc is scratched, dirty, or incompatible type (e.g. some CD-Rs) ([reddit.com](https://www.reddit.com/r/Cd_collectors/comments/1sq73q4/dm13_not_reading_cds/?utm_source=openai)). Also cleaning the CD lens might help.  \n\n---\n\nIf you want, I can walk you step-by-step with *just feel*, so you can solve this without needing to see. Would you like that?"

([manuals.plus](https://manuals.plus/asin/B0DK5996CS?utm_source=openai))  \n   \u2022 Press and hold that power button for about **3 seconds** until you feel a click or some resistance (that\u2019s to power it on). ([m.media-amazon.com](https://m.media-amazon.com/images/I/81gkVUxgtLL.pdf?utm_source=openai))\n\n3. **Ensure output mode is set to headphone (analog)**  \n   \u2022 Once the device is on, immediately **short press** the same power button (**leftmost, top row**). This makes the display announce battery or status. ([fiio.com](https://www.fiio.com/newsinfo/974467.html?utm_source=openai))  \n   \u2022 Then **short press it again** to cycle the output mode. You want it to land on **PRE OUT** mode (analog output), which is the mode that sends sound to the headphone jacks. ([fiio.com](https://www.fiio.com/newsinfo/974467.html?utm_source=openai))\n\n4. **Start the CD playing**  \n   \u2022 Feel for the **Play/Pause** button \u2014 it\u2019s one from the left, second button in the top row. ([manuals.plus](https://manuals.plus/asin/B0DK5996CS?utm_source=openai))  \n   \u2022 Press it *once* to start playback. ([manuals.plus](https://manuals.plus/asin/B0DK5996CS?utm_source=openai))\n\n5. **Adjust the volume**  \n   \u2022 There are two buttons near the right side of the top row: one is **Volume Down**, one is **Volume Up**. Feel them by their + / \u2212 signs or height if tactile. ([manuals.plus](https://manuals.plus/asin/B0DK5996CS?utm_source=openai))  \n   \u2022 Press the **Volume Up** button a few times to get the sound loud enough. If it\u2019s too loud or uncomfortable, press Volume Down.  \n\n---\n\nIf after following this you don\u2019t hear anything:\n\n- Make sure the CD is inserted properly: slide the side **Eject** switch to open the top cover, put in the CD with the shiny side down, then close it. ([fiio.com](https://www.fiio.com/newsinfo/974467.html?utm_source=openai))  \n- Double-check that you have the output mode *exactly* on PRE OUT\u2014not USB OUT, SPDIF OUT, or BLUE OUT. ([fiio.com](https://www.fiio.com/newsinfo/974467.html?utm_source=openai))  \n\n---\n\nIf you want, I can also give you a *verbal short script* you can memorize and say out loud to yourself, so you always have the shortcut steps ready. Do you want that?"

Let\u2019s walk through more details by feel and inspect the ports you have \u2014 and I\u2019ll explain exactly the two USB ports, so you can know which is which and how to use them correctly.  \n\n---\n\n## \ud83d\udd0c Two USB Ports: What Each One Is\n\nThe FIIO DM13 has two Type-C USB ports. Here's what each does:  \n\n- **\u201cPOWER IN\u201d port**  \n  \u2022 This is mainly to charge the device or power it. Using 5 V at 2 A is recommended. ([fiio.com](https://www.fiio.com/dm13_parameters?utm_source=openai))  \n  \u2022 It also can be used to plug in a USB drive when you're ripping tracks from a CD (when DM13 is in USB OUT mode). ([manuals.plus](https://manuals.plus/m/b5978bd2898e6763d7c17e1a23f6995af808800e671e0547d6ac17bddc2a308e?utm_source=openai))  \n\n- **\u201cUSB REC\u201d port (sometimes called USB AUDIO / data port)**  \n  \u2022 This port is for data transfer \u2014 for example, connecting to a computer to record (or rip) the CD contents. ([fiio.com](https://www.fiio.com/dm13_parameters?utm_source=openai))  \n  \u2022 It also can supply power or charge, but its main purpose is data when in the correct mode. ([fiio.com](https://www.fiio.com/dm13_parameters?utm_source=openai))  \n\nSo, to get audio out through the headphone jack (front jack), you should *not* have to worry about the USB ports unless you're doing something special (recording or ripping, or connecting to a computer).\n\n---\n\n## \ud83c\udfa7 If Still Nothing\u2019s Playing: Step-by-Step By Feel\n\nBlacklist what you're not sure about. Let\u2019s check all the key things by feel, in a slow, logical order. Use this as a checklist.\n\n| What to Do | Feel & Action | Why This Matters |\n|------------|----------------|------------------|\n| Step 1: Check headphone jack | Touch front of unit, identify the two headphone holes. Plug your headphones into the **3.5 mm PO** (smaller) jack if you're using a normal headset. | If not plugged in, no sound. |\n| Step 2: Power on | Press and hold the **power button** (the leftmost top button) for 3 seconds until you feel it \u201cwake up.\u201d | If device is off, nothing works. |\n| Step 3: Wait a moment | Give it 5-10 seconds after turning on before doing more. | The device needs to initialize. |\n| Step 4: Set output mode to \u201cPRE OUT\u201d | Briefly press the power button short\u2014once to hear status, then again to switch to output mode. Keep pressing until you believe it\u2019s PRE OUT (analog output). | If mode is in USB OUT / SPDIF OUT / BLUE OUT, sound won\u2019t go to headphone jack. ([fiio.com](https://www.fiio.com/newsinfo/974467.html?utm_source=openai)) |\n| Step 5: Play the CD | Press the **Play/Pause** button (the second button from the left in the top row). | If you didn\u2019t start play, silence. |\n| Step 6: Adjust Volume | Find **Volume +** button \u2014 likely two buttons toward the right \u2014 press until it\u2019s loud enough. | Volume might be down or muted. |\n\n---\n\n## \u26a0\ufe0f Other Things to Try or Check\n\n- **Check battery**: If battery is zero, maybe device won\u2019t output sound until charged. Try plugging in the charger via the POWER-IN port. ([manuals.plus](https://manuals.plus/asin/B0DN6Z2XZK.pdf?utm_source=openai))  \n- **Check PRE OUT vs other modes**: The \u201cWhy I get no output from the headphone port\u201d support page says if it\u2019s *not* switched to PRE OUT, the front headphone jack won\u2019t work. ([fiiosupport.freshdesk.com](https://fiiosupport.freshdesk.com/support/solutions/articles/69000869735-why-i-get-no-output-from-the-headphone-port-in-dm13-?utm_source=openai))  \n- **Firmware bug possibility**: There are reports from other users that sometimes after restarting, the analog output (headphone jack) doesn\u2019t come on until doing something like using Bluetooth then switching back. Might be firmware. ([reddit.com](https://www.reddit.com/r/FiiO/comments/1ovks5g/fiio_dm13_no_sound_from_aux_line_out_until_i/?utm_source=openai))  \n- **Try different headphone or cable**: If you have another pair of headphones you know work, try them to rule out cable issue.\n\n---\n\nIf you like, I can try to give you a verbal diagnostic steps you can try (yes/no) to find exactly where the problem is. Would you prefer that?"

Let me know if you want to walk through checking if the CD is registering now."
