I've been struggling with this for a while. Updated all drivers I could, no luck. Headphones connect and pair successfully, appear in manager, show all services correctly, but don't appear as a playback device. Any help would be appreciated.

Here are the details:

Windows 10 build 17127

Headphones QC12 with AptX

Killer Wirelesss Bluetooth


device manager bluetooth settings device props sound manager services

  • Let me rephrase, I might've been unclear. I am connecting my headphones to the PC, so I could play sound FROM pc TO headphones. – reflog Apr 4 '18 at 13:32
  • Let me ask again, what happens when you play something on your PC? Does it play from the headphones? – Ultrasonic54321 Apr 4 '18 at 13:38
  • @PimpJuiceIT - tried the unplug - full uninstall - plug, same result. And yes, the last screenshot shows all sound devices (disabled and unplugged). The headphones don't appear there :( – reflog Apr 5 '18 at 20:17
  • Okay, great.... Can you tell the make and model of the computer? Perhaps the motherboard if it's a custom built PC but otherwise the make and model if you bought from a specific vendors e.g. Dell, HP, etc.? – Pimp Juice IT Apr 5 '18 at 21:29
  • Try this: Plug in the headphones, right-click the speaker icon, click Playback devices, right-click the default speakers and select Show disabled devices and Show disconnected devices. If your headphones now appear, right-click them and select Enable. – harrymc Apr 6 '18 at 9:53

The usual procedure is :

  • If wired, plug in the headphones. If Bluetooth, pair and ensure they are visible in Bluetooth Neighborhood.
  • Right-click the speaker icon and click Playback devices
  • Right-click the default speakers and select Show disabled devices and Show disconnected devices.
  • If your headphones now appear, right-click them and select Enable.

If your headphones are still unusable, then the problem is with your driver. It may be incapable of functioning as a playback device. Search for the right software, or contact the Support of the manufacturer. If nothing works, change headphones.

  • Headphones are unavailable in the list. atheros qca61x4 (my bluetooth chip) is fully supported by Windows, so i doubt that's the issue – reflog Apr 12 '18 at 8:05
  • Your problem is with these particular headphones and their implementation. This procedure is the only one I know for this problem. If it doesn't work, then there is a problem, either with the hardware or the driver. The Support of the manufacturer might be the only one capable of offering more help. – harrymc Apr 12 '18 at 8:38
  • The thing is - I have another headphones that have the same issue but I also have a Linux system dual boot in which they work, so I know it's not the chip... – reflog Apr 12 '18 at 10:28
  • It's the interface between the headphones and Windows, normally the the driver. – harrymc Apr 12 '18 at 10:34

I encountered the same problem with Win 10 and my dell computer/LG Bluetooth speaker. I accidentally found the way to resolve the problem by referring to the answer from the previous contributor Dlight202.

2 simple steps:

  1. In Start , search for "devices and printers", found your device (speaker)

  2. Right click to show properties, under Services, check "audio sink", click "apply" then the speaker works.

I'm not sure if it works for all speakers but it works for mine.

  • I just wanted to say thank you!!! This solved my problem! I was having with my Bluetooth in-ear headphones for the last week or two and was thinking of just tossing them. You saved them! Thank you! – Justin M Apr 2 at 14:04

Have you tried uninstalling and re-installing your Bluetooth adapter?

If so then try the following steps:

  1. Remove QCY-QY12 from Bluetooth
  2. Hold the power button while charging until you see the LED flash three times.
  3. Unplug and power the headphones.
  4. Try pairing again.

There are two solutions that I found

Solution one : try to install Bluetooth Suite Win 7 & from Atheros. It can be searched and downloaded online for win 7 and lower.

Solution two : buy a bluetooth 4.0 dongle and connect to your headset.

There is a reason for it but I am not a real tech. Anyways hope people like me not to get frustrated anymore.

I recently had a similar issue with my windows 10 laptop. My bluetooth headset would connect, but then would not appear as a playback device in my sound manager.

The bluetooth device used a Qualcomm Atheros driver. I tried uninstalling, using old drivers, the latest dell supported driver, third party atheros drivers, but nothing was working.

The headset would connect okay, but then afterwards during enumeration, it didn't seem to enumerate correctly. What I found is that when I looked in devices and printers and then at the properties for my headset, and hardware tab, there was no sound type device functions associated. There were however, 3 virtual bluetooth types, that when I right clicked to properties, were associated with the atheros driver.

When I uninstalled the bluetooth driver, the generic microsoft bluetooth driver would associate, but the same virtual bluetooth types were still showing up as device functions after enumerating, and they were still associated with the atheros driver. I had to remove the atheros drivers inf files from windows 10 driverstore by running the pnputil from command line.

First to search the listed drivers to find the ones related to bluetooth

pnputil -e > C:\Users\<username>\Desktop\driver_list.txt

Then after searching the list, delete the ones with the appropriate oem number

pnputil.exe -d oem<NUMBER>.inf

After this, when using the generic windows bluetooth driver the device re-enumerated and then the correct hardware device functions became available.

good luck
