Windows 10: Bluetooth Headphones connected in Windows 10 after fresh install, but for voice and not music

I recently performed a fresh install of Windows 10 Pro on my PC - prior to doing so I had my Bose QC35s paired and it worked great. I remember in the days of Windows 7, getting Bluetooth to work was practically a sacrificial ritual you had to perform. I was really pumped about Windows 10 because of how much MS improved Bluetooth. After I reinstalled, I was able to pair my headphones in a few seconds, but I noticed Windows had paired them a bit differently than on my previous installation.


At the time of writing this, I'm running Windows 10 Pro 1909 Build 18363.815, so I'm fairly certain I'm up to date with everything...Windows Update is showing that lovely"You're up to date"message too.


Before, within the Windows Settings "Bluetooth and other devices" menu, underneath the "Audio" section, my headphones would be listed as they are now, but below it would say "Connected voice, music". Now the headphones just say "Connected voice". I didn't think this was a big deal until I attempted to use my headphones with Windows 10. The result was god awful, ear piercing, abrasive sound quality that I wouldn't wish on any other living thing.


Now, I know my headphones aren't the best on the market, but they aren't exactly tin cans either... plus they sounded so much better prior to reinstalling Windows and sound great on any other device. Is there a way to change the device from this menu to be used for music as well? That'd be really handy!


I took a look in the Sound settings the "Sound" Control Panel menu for Windows to try and fix this, and I noticed there was a big difference under "Playback" from before I reinstalled my device's name is the one very obviously blacked out:



In the image above is what I had under 'Playback" in Windows before reinstalling, minus one difference. The difference is, the "Stereo" device didn't show as disconnected. This doesn't make much sense - how can the "Headphone" device be disconnected if the "Headset" device connected without issues? They're the same device!


So next I ventured into services.msc, to check that all Bluetooth services were running correctly:

ALSO, if there's any other services I should be checking, let me know! I'm not a Windows expert by any means



Everything looked fine and dandy there.


The device is showing up normally in Device Manager under "Bluetooth" my device's name is the one very obviously blacked out:



The device is showing up normally in Device Manager under "Audio inputs and outputs" my device's name is the one very obviously blacked out:



I found it odd here that the same device would be coming up twice - shouldn't one of those be my Stereo device like before?

Under "Devices and Printers", my headphones show no errors my device's name is the one very obviously blacked out:



Within the "Properties" window accessed from my device within "Devices and Printers", the Stereo device I mentioned being connected before I reinstalled is visible third from the bottom, my device's name is the one very obviously blacked out:



So if Device Manager and Devices and Printers show no errors, and the Properties of the device itself show the Stereo device, it should be working correctly right?


I've tried all sorts of things, Windows Troubleshooting the device, attempts on updating drivers, and updating drivers via Windows Update have done nothing. As I've said before, I'm fully up to date running the latest possible build... I even updated my Bluetooth driver to the latest version available from my manufacturer. The Bose QC35s have been updated as well. Maybe Bose broke something in their last update? Then again.... they still work perfect on any other device....


At this point I basically accepted the fact that I was stuck with horrible quality audio, the cause of which was Windows electing to treat my headphones as a hands-free headset instead of a pair of headphones. This really bummed me out because I'm genuinely stumped as to what's wrong here - not to mention that the Stereo device that worked before is showing up in Windows, but is mysteriously rendered unusable.


Since I'm stuck with one device, I tried to at least improve the quality by right-clicking the "Hands-Free AG Audio" device in Sound and clicking properties. From the "Advanced" tab, I noticed somethinghilarious that explained the unbearable audio quality:



As you'll notice, my device is using... tape recorder quality? To make matters worse, it's locked to that setting, and unchecking the checkboxes below can't change that either...


Why in the world would Windows 10, one of the most widely used operating systems on the planet, elect to use tape recorder sample rate/bit depth on a pair of Bose QC35 headphones? Also, can you even hook a tape recorder up to Windows 10?


All jokes aside, if someone could advise me on either:

1. Changing the quality of the sound device I appear to be stuck with

2. Getting the sound device that worked before reinstalling to work again

3. Somehow changing the device to appear to be used for both voice and music under the Windows Settings Bluetooth menu


Has anyone else struggled with an issue similar to this recently? From a quick Google search I see a few posts from a few years back with similar issues and similar devices.

Bluetooth Headphones only connect to voice and music

Today my headphones started to only use voice and music, when yesterday [the day i got them] they did all noise. I have re paired the headphones to the computer, remove and re add them to the computer list, and remove the computer from the headphones bluetooth
list. Everytime I reconnect them they just say connected to voice and music.

 

Cannot connect to bluetooth headphones after upgrade to Win10


I upgraded my Lenovo W530 running Win7 Pro 64 bit to Windows 10. After the upgrade I can no longer connect to my bluetooth headphones which worked before the upgrade. The bluetooth radio is on. When I click Connect in the Action Center it shows that the headphones are connected but they are not. The headphones (actually my hearing aids) play a notification sound when a bluetooth connection is made and I never hear that sound. If I play music the sound goes to the speaker, not my headphones. I have removed the headphones and repaired them. I have checked that all of the bluetooth device drivers are up to date in Device Manager. I would really appreciate any suggestions to solve this problem. Thanks.

 

Listen to Android phone's music from desktop headphone

How to listen to [Android phone's music] from [a headphone that is connected to a Windows 10 desktop] without internet connection?
I have an Android phone (Pixel 3a) with YouTube Music installed on it.

When I don't have internet connection, I want to be able to wear my headphone, which is connected to my desktop (Windows 10) and listen to both my desktop's audio (for example, game sound) and the music playing on my phone (for example, music that is available only on the phone's YouTube Music offline downloaded folder).

How can I achieve this?

Note:

• I searched on the internet and it seems like Windows 10 doesn't have bluetooth support by default that support audio streaming from phone to PC. People seems to be able to install a different bluetooth driver and get it to work, but I can't get it to work. (if you can get it to work please list the exact step)
  
  
• This source says Pixel 3a has A2DP.
