How to sync volume levels between bluetooth headphones and system?

Question

linux

Good afternoon.
I would like to achieve the same behavior as on Android and in Windows 10.
Now the volume is separate: on the headphones, its own, in the system. A2DP profile, everything works as it should on HSP, but the sound is shit, as you understand.

Answer 1

This is a special function of Windows, personal volume for different devices, as well as for different applications.
Most likely you need to look for a separate software that will synchronize the volume.
