no mic input - headset Soundcore Spirit X2 - bluetooth

[akrueger]

Bluetooth headset works only as headphones, i.e. no microphone yet. It's a "Soundcore Spirit X2", and in Windows its microphone input is recognized too, but in Debian only headphone output.

Vendor's answer:

> no Mic output on your Linux computer
> I'm so sorry. I consulted our technical staff. This is a compatibility problem between the Bluetooth headphones and the sound card driver from the computer. Other brands of headphones also have this problem that cannot be temporarily resolved.

Any ideas what I could do now? Or who is working on an experimental driver perhaps?
