Windows 10: Bluetooth headphones' sound not working on Windows after dual booting ubuntu

Recently I had installed ubuntu 20.04.3 alongside Windows 10 on my laptop. After that I had problem with sound on my wireless headphones on Windows 10. The sound is working perfectly on ubuntu and there is no problem with bluetooth connection but on Windows not only do I have a problem with pairing and connecting headphones via bluetooth this process takes a lot of time and fails many times as well but when I finally connect them sound starts cracking after arbitrary amount of time. I tried uninstalling drivers but I am not sure I made every possible action to solve this problem.

Help with dual booting Win 10 and Ubuntu

This is your whole problem. What you should have done is to put GRUB in sdb1 and Windows Manager in sda1 so that Windows Boot Manager is in control.
So what suggested above will not make any difference. GRUB is still in control of booting process.
To fix your problem. You will need to:

1. Move GRUB from sdb to sdb1
   |grub2 - how to move grub boot from one partition to another in linux - Ask Ubuntu
2. Rebuild The Windows Boot Manager ie. create a brand new BCD to boot Windows 10.
3. Once done with steps 1 and 2 above. Windows will not know UBUNTU exists and vice versa.
   Depend on the priority set in the BIOS, it will boot directly into that OS.
   However, you can boot either one from Boot Menu (Using whatever key that your Laptop assigned to: F2, F10....)
   Since I hate Dual Boot and seldom boot into Linux, I will stop here.
   Now, go to step 4 to create dual boot.
4. Use Easy BCD to create an entry for dual boot with UBUNTU. Once done, you should get a nice GUI dual Boot Menu
   and it will boot directly into either Windows or UBUNTU.

Here's the detailed explanation: How can I move windows 10 boot files to another drive to allow linux

 

Bluetooth headphone sound volume keeps changing.

I have a relatively new Bluetooth Pulse Echo headphone set and an Acer Aspire 3 notebook that has Windows 10 O/S. When I use the headphones with the notebook in wireless mode the sound volume alternates between normal and very low. I have run Windows Bluetooth fault finder and disabled sound enhancements to no effect. The headphones work fine in conjunction with my iPad however.
Could anyone suggest a solution for this problem please?
