        "content": "When you say only one device\u2014either the *Stereo* or the *Hands-Free* (voice) profile\u2014can connect after moving your Bluetooth adapter directly to your PC, what's probably happening is a common limitation of how Windows handles Bluetooth audio profiles. I'll explain what\u2019s going on, and then how to try to get both working at once (or at least make switching smoother).\n\n---\n\n## What are these profiles and why do they conflict?\n\nBluetooth audio devices (headphones, headsets, etc.) generally support multiple \u201cprofiles\u201d:\n\n- **A2DP (Stereo / Advanced Audio Distribution Profile)** \u2014 high-quality, one-way audio (music, media).\n- **HFP / HSP (Hands-Free Profile / Headset Profile)** \u2014 two-way audio for voice/mic (calls, voice chat), but much lower quality for speaker output (mono or downgraded).\n\nOn Windows, these appear as *two separate audio devices* under Settings \u2192 Sound / Bluetooth: one is \u201cStereo\u201d (A2DP) and the other \u201cHands-Free AG / Headset\u201d (HFP/HSP). ([support.logi.com](https://support.logi.com/hc/en-us/articles/34961953160599-Why-does-my-headset-appear-as-more-than-one-device-on-Windows?utm_source=openai))\n\nWindows can\u2019t truly use both profiles fully at once for a single Bluetooth device: you either get the high-quality output of A2DP, or the voice call capability (mic + speaker) of HFP/HSP. Trying to have both at once is generally restricted due to hardware and Bluetooth stack limitations. ([reddit.com](https://www.reddit.com/r/windows/comments/13o8r90?utm_source=openai))\n\n---\n\n## What changed when you moved the adapter?\n\nWhen you plugged a Bluetooth adapter directly (USB or internal) into your PC, you likely changed:\n\n- **Which Bluetooth radio and driver are being used** (built-in vs external or from another vendor).\n- **Driver version or stack** that supports certain profiles\u2014or doesn\u2019t support them well.\n\nThis can lead to A2DP (Stereo) being disabled, not negotiated properly, or conflicting with HFP/HSP, so only one profile gets activated. Many users report that after installing generic or incorrect drivers, the \u201cStereo\u201d profile disappears or gets marked \u201cDisconnected\u201d. ([learn.microsoft.com](https://learn.microsoft.com/en-us/answers/questions/4379311/bluetooth-speaker-only-shows-hands-free-audio?utm_source=openai))\n\n---\n\n## What you can try to get both to be usable (or switch more easily)\n\nHere are steps to diagnose and hopefully fix this so that you can use both profiles as needed:\n\n1. **Update Bluetooth & Audio Drivers**\n   - Go to Device Manager \u2192 Bluetooth \u2192 your adapter \u2192 Update driver.\n   - Also check your PC or adapter manufacturer\u2019s website for a dedicated Bluetooth audio driver.\n   - Update audio drivers (especially if using Realtek, Intel-based audio etc.). Many times this fixes the missing \u201cStereo\u201d device. ([support.logi.com](https://support.logi.com/hc/en-us/articles/34961953160599-Why-does-my-headset-appear-as-more-than-one-device-on-Windows?utm_source=openai))\n\n2. **Check Bluetooth Audio Device Properties**\n   - In **Control Panel \u2192 Devices and Printers**, find the Bluetooth device, right-click \u2192 **Properties** \u2192 **Services**.\n   - Make sure *Audio Sink* (A2DP), *Remote Control*, etc. are enabled. If *Hands-free Telephony* is the only one enabled, stereo may never work. ([learn.microsoft.com](https://learn.microsoft.com/en-us/answers/questions/3759603/%28solved%29bluetooth-earbuds-only-shows-as-hands-free?forum=windows-all&utm_source=openai))\n\n3. **Disable Hands-Free Temporarily (if you just want stereo)**\n   - If you don\u2019t need the mic, disable the *Hands-Free Telephony* service in device properties. Then re-pair or disconnect/reconnect. This often forces Windows to connect using the stereo (A2DP) profile. ([headphonesty.com](https://www.headphonesty.com/2022/10/windows-11-bluetooth-audio-not-working/?utm_source=openai))\n\n4. **Re-pair the Bluetooth Device**\n   - Remove (unpair) the device from Windows (Settings \u2192 Bluetooth & Devices \u2192 Remove).\n   - Turn Bluetooth off/on or reboot.\n   - Put your headset into pairing mode and reconnect, making sure the PC sees *both* profiles during setup (sometimes it indicates \u201cvoice, music\u201d connected simultaneously). ([reddit.com](https://www.reddit.com/r/CODWarzone/comments/fqls6j/no_audio_on_bt_headphones_unless_i_select/?utm_source=openai))\n\n5. **Check Bluetooth Support & LE Audio (if Available)**\n   - Bluetooth LE Audio is newer; some devices and Windows 11 PCs support it, enabling better functionality. ([assets-je.cas.dgs.com](https://assets-je.cas.dgs.com/-/media/oticon/main/pdf/australia/24point2/lions/61275294au_ug_ot_hands-free_troubleshooting_android-pc-le_audio.pdf?hash=69B9F044F07A9CDD02BC30DD088F1E77&la=en-AU&rev=BA8F&utm_source=openai))\n   - If your adapter & headset both support LE Audio, this might help with simultaneous profiles or better switching.\n\n6. **Windows Version / Settings Differences**\n   - On Windows 11, some driver improvements help profile switching and reduce separate device listings. ([support.logi.com](https://support.logi.com/hc/en-us/articles/34961953160599-Why-does-my-headset-appear-as-more-than-one-device-on-Windows?utm_source=openai))\n   - On Windows 10, you\u2019ll likely still need to manually switch between \"Stereo\" for media or \"Hands-Free\" for calls. ([support.logi.com](https://support.logi.com/hc/en-us/articles/34961953160599-Why-does-my-headset-appear-as-more-than-one-device-on-Windows?utm_source=openai))\n\n---\n\n## Bottom Line\n\n- Your PC adapter likely changed the Bluetooth radio or driver, and now Windows is only able to negotiate one profile at a time (either stereo *or* hands-free).\n- Unfortunately, this is a known limitation of Windows/Bluetooth stacks\u2014it\u2019s usually not possible to get full high-quality stereo audio and voice input simultaneously over classic Bluetooth with a single device unless the adapter and device support newer standards (LE Audio etc.).\n- But you *can* improve the situation: update drivers, ensure audio services are enabled, disable the voice profile if you only need music, and re-pair the device.\n\n---\n\nIf you want, I can walk you through checking whether your specific adapter and headset support LE Audio, or help find drivers for them\u2014if you tell me the exact adapter model and headset name."

        "content": "Cool detail\u2014knowing it's a TP-Link **UB500** helps a lot. I've dug into recent info; here's what I found, and some ideas for what's going on + what you can try next.\n\n---\n\n## What I discovered about the UB500\n\n- According to TP-Link, the UB500 *does* officially support A2DP, AVRCP, HFP, and HSP. ([tp-link.com](https://www.tp-link.com/us/support/faq/2744/?utm_source=openai))  \n- But there are also threads (on TP-Link forums and Reddit) where people say: when using the UB500 on Windows 11, sometimes the **Hands-Free (HFP)** profile (which includes the microphone) is *not* visible in settings \u2014 even though the device shows up in Device Manager under mono and stereo entries. ([community.tp-link.com](https://community.tp-link.com/en/business/forum/topic/864038?utm_source=openai))\n\nSo it seems like UB500 *should* handle both profiles\u2014but there\u2019s a real-world issue where sometimes Windows only exposes one.\n\n---\n\n## Hypotheses for what changed after you moved the adapter to the PC directly\n\nHere are plausible reasons based on what\u2019s documented:\n\n1. **Power State Differences**  \n   Even with a powered hub, sometimes there's subtle power conditioning or voltage regulation that can keep USB devices in a state more favorable for stable communication. When plugging directly into the PC, USB port power variations (especially under load or depending on motherboard/USB controller) might upset the Bluetooth adapter's ability to advertise or negotiate all services. If the power is borderline, Windows might drop or fail to initialize some profile services (especially HFP, which involves extra work).\n\n2. **USB Port / Controller Differences**  \n   Hubs sometimes share a USB controller, or are connected to a different USB root hub or host-controller chip. Moving directly might mean you're plugging into a port that's run by a different controller (older USB2 vs USB3, or a controller that lacks enough bandwidth/reserved endpoints) and that could interfere with profile negotiation. Bluetooth sends audio over different channels/protocols when switching profiles (SCO/eSCO for HFP vs streaming for A2DP), so controller quirks matter.\n\n3. **Driver / Firmware Interactions**  \n   There's a known issue for certain UB500 firmware versions where HFP behavior is broken or not registered properly in Windows 11. Some users report that Stereo (A2DP) works fine, but the mic (HFP) is invisible. ([community.tp-link.com](https://community.tp-link.com/en/business/forum/topic/864038?utm_source=openai))  \n   \n   Also, depending on the USB port's speed (USB 2.0 vs 3.0/3.1) and driver stack, sometimes the adapter firmware may fail to load the part that handles voice (SCO/eSCO) channels. Or Windows might choose not to present the HFP profile if it detects something unusual during startup or connection.\n\n---\n\n## What you can try to fix it or get both profiles back\n\nHere are actionable steps specifically for UB500 + moving it back to direct PC connection:\n\n- **Use a Different USB Port**  \n  Try both USB2.0 and USB3.x ports (front vs back, motherboard port vs via case), to test whether it's about the USB controller or power. Sometimes rear USB ports provide more stable power and bandwidth.\n\n- **Check and Update Firmware / Drivers for UB500**  \n  TP-Link posts firmware and drivers for UB500. Make sure yours matches the latest official TP-Link release. If you\u2019re using a version that people are complaining about (e.g. **Firmware Version: 1.9.1038.3023** has been mentioned as having issues) maybe try seeing if there\u2019s a newer one or an alternate driver. ([community.tp-link.com](https://community.tp-link.com/en/business/forum/topic/864038?utm_source=openai))\n\n- **Disable Conflicting Bluetooth Radios**  \n  If your PC has built-in Bluetooth *and* the UB500, Windows might still try to use both or mix profiles between them. Try disabling the built-in one via Device Manager to force Windows to only use the UB500 and see if that restores proper dual-profile behavior.\n\n- **Repair the Device**  \n  Unpair the headset/headphones, reboot, and pair again *with* the UB500 directly connected. Sometimes \u201cprofiles\u201d get cached in a bad state. Resetting pairing forces clean negotiation.\n\n- **Check Windows Sound & \u201cShow Disabled / Disconnected Devices\u201d**  \n  In recording/playback settings, turn on \u201cShow Disabled Devices\u201d and \u201cShow Disconnected Devices\u201d to see if the missing profile is just hidden. Then enable it. Users have reported that the HFP endpoint is visible in Device Manager but invisible in those sound settings. ([community.tp-link.com](https://community.tp-link.com/en/business/forum/topic/864038?utm_source=openai))\n\n- **Try Using a Powered Hub Again as a Test**  \n  If everything works as expected with the powered hub but not when plugged directly, that\u2019s a strong signal it\u2019s power or port controller related. If so, you might prefer to keep using the hub (if it's powered and good quality) to ensure stability.\n\n---\n\nIf you like, I can help you check whether the specific firmware version your UB500 has is known to have a bug (including examining TP-Link release notes) and see if there\u2019s a fix. Want me to pull that in for your setup (Windows version + firmware)?"

        "content": "Great that you\u2019re running Windows 10\u2014turns out that\u2019s *very helpful* for your situation, according to recent feedback from the TP-Link user community. Here\u2019s what I confirmed and what specific steps might help you fix it:\n\n---\n\n## What I found specific to UB500 + Windows 10\n\n- TP-Link officially states that the **UB500 adapter supports A2DP, AVRCP, HFP, and HSP** profiles\u2014so *all* should be available. ([tp-link.com](https://www.tp-link.com/us/support/faq/2744/?utm_source=openai))  \n- On TP-Link\u2019s driver page, there\u2019s a version *1.9.1051* for UB500 (hardware version V1) that supports **Windows 10** (and 11). ([tp-link.com](https://www.tp-link.com/ca/support/download/ub500/v1/?app=&utm_source=openai))  \n- A user reported: UB500 + Windows 10 works fine (both audio output *and* mic) for the **same headset** that failed to work under Windows 11 with UB500. ([community.tp-link.com](https://community.tp-link.com/en/business/forum/topic/864038?utm_source=openai))  \n\nSo evidence shows you *should* have access to **both profiles** on Windows 10 with your UB500.\n\n---\n\n## What likely went wrong when you plugged into the PC\n\nEven though Windows 10 supports both profiles with UB500, moving adapters or ports can disrupt things. Some likely issues:\n\n- Old or wrong driver still installed (Microsoft\u2019s generic Bluetooth driver or a driver configured for another adapter).  \n- Device pairing \u201ccached\u201d under a previous adapter/port, with only one profile negotiated successfully at that time.  \n- Windows \u201caudio endpoints\u201d didn\u2019t get updated fully, so one profile (often HFP) failed to load or got \u201cdisabled.\u201d  \n- Port or USB controller issues (power or USB bus quirks) still interfering, though less common in Win10 with UB500.\n\n---\n\n## What to try now (step-by-step) on Windows 10\n\nHere\u2019s a more targeted checklist given your setup:\n\n1. **Check and install the correct UB500 driver (for Windows 10)**  \n   - Go to TP-Link\u2019s support \u2192 UB500 \u2192 your hardware version (V1, V2, etc.). ([tp-link.com](https://www.tp-link.com/ca/support/download/ub500/v1/?app=&utm_source=openai))  \n   - Download \u201cUB500(UN)_V1_Windows_1.9.1051\u201d (or correct version for your hardware). ([tp-link.com](https://www.tp-link.com/ca/support/download/ub500/v1/?app=&utm_source=openai))  \n   - Install manually (run setup as admin). Then reboot\u2014even if Windows already auto-installed something.\n\n2. **Remove existing Bluetooth pairings and endpoints**  \n   - In *Settings \u2192 Bluetooth & Devices*, remove your headset.  \n   - In *Device Manager \u2192 Sound, video and game controllers* and *Audio inputs and outputs*, remove any entries related to the headset (Stereo, Mono, Hands-Free, etc.).  \n   - Optionally, open *Device Manager \u2192 Bluetooth*, remove the adapter and re-plug it (if needed). Reboot.\n\n3. **Pair from scratch**  \n   - Put headset in pairing mode.  \n   - In Bluetooth settings, add the device. After pairing, check *Playback Devices* and *Recording Devices* (in **Sound Control Panel**, not just Settings \u2192 Sound) to see whether *Stereo* and *Hands-Free* show up separately. Also check \u201cShow disabled/disconnected devices.\u201d If Hands-Free is disabled, enable it.\n\n4. **USB port swapping if needed**  \n   - Try plugging the UB500 into a different port (preferably rear-ports, directly on motherboard) if possible. Even though Windows 10 is more stable in this respect, port differences still matter.\n\n5. **Disable built-in Bluetooth adapter (if present)**  \n   - If your PC already has Bluetooth, disable it via Device Manager so only UB500 is used. Sometimes built-in + external adapters confuse Windows into using one for mic, one for audio, or dropping a profile.\n\n6. **Check app-level settings**  \n   - For apps that need the mic (Zoom, Discord, etc.), make sure the \u201cHands-Free\u201d device is selected under **Input / Microphone**. Also, in *Sound > Recording Devices*, ensure the headset\u2019s HFP mic is set as default or \u201cCommunication Device\u201d if used for calls.\n\n7. **Windows Update & Optional Drivers**  \n   - Check \u201cOptional Updates\u201d in Windows Update to see if there\u2019s a newer Bluetooth/driver update. Even if the TP-Link driver is installed, sometimes Microsoft pushes patches that fix profile negotiation.  \n\n---\n\nIf you go through all that, there\u2019s a very good chance you\u2019ll be able to get both profiles back again in Windows 10 as you had before. If after trying all that you still only see one, let me know which headset you\u2019re using and which Windows 10 build version (type \u201cwinver\u201d in the Start menu). I can help debug further."
