In this state, even after attaching a mic, attempt to record anything with audacity results in only Overflow calculating amount of data there is room for???? messages and nothing gets recorded. I do see Setting audio-input to enabled and Recording start messages at dom0 side.

Recording with pw-record results in out of capture buffers: Broken pipe messages (and also nothing gets recorded).

I was unable to reproduce the issue on Debian 12 (xfce) template. Debian has audacity 3.2.4, Fedora has 3.4.2, but the relevant difference may be in some different part of the software stack (pipewire? some other lib?).

I got this issue with pipewire-qubes 4.2.14 (there is no audio-related changes since then).

In fact, the issue happens also when attaching a mic before starting audacity. There is a lot of Recording start/Recording stop messages during audacity startup.

Tested in 4.2, both with sys-audio and by directly attaching a hardware device in fedora-40-xfce.

  1. Issue exists only when attaching dom0:mic, hardware device works fine
  2. I don't see any signs of a functioning microphone in pavucontrol either, and it throws very similar errors while pavucontrol gui is open (and audacity is not):
