Microphone on sys-audio

User Support

Does anyone of you use audiovm/sys-audio (a separate machine for sound) in qubes os?
I have configured it so that my headphones with a microphone work.

I connected them in blueman (Audio profile Headset Head Unit (HSP/HFP, codec mSBC).

The sound works from appVM.

The microphone does not work. In pasystray it can be seen in “Default source”. It is selected. When I say something, it is visible in Volume Control on the progress bar.
In recording tab from Volume Control i see my appVMs and I can see when I say something on this progress bar.

Unfortunately, no one can hear me in appVM. The selected microphone is “Qubes Virtual Audio Source” (only avaiable)

policy.d I have from the file qusal/salt/sys-audio/files/admin/policy/default.policy at main · ben-grande/qusal · GitHub

What could I have forgotten?
OS: Qubes OS 4.2.4

Okay. I already know what I forgot. I’ll leave some info for everyone who stopped at the same stage:

Even if we use sys-audio, we need to attach the microphone to a specific AppVM in the system tray (Qubes Device Manager Icon) in the “Microphone” section. Then the transfer of sound from the microphone (USB microphone/bluetooth/PCI microphone jack) between virtual machines (sys-audio ↔ AppVM) works.

Recording streams: requires selecting the AppVM on Qubes Device Manager to which the sound will be passed, even if you use a dedicated audioVM (sys-audio) to handle sounds.
