How to file a helpful issue

Qubes OS release

R4.1

Brief summary

If a qube does not have a microphone assigned to it, it will never receive input on the recording vchan. With the current implementation of the Linux PulseAudio agent, this causes applications to think there is a microphone present, but that microphone never produces any audio samples and so appears to be broken. The result of this is application-dependent: gnome-sound-recorder pauses audio recording, while Discord refuses to use it and requires me to disconnect and reconnect from the call.

Steps to reproduce

Have an application try to record audio in a qube with no microphone attached to it.

Expected behavior

From the application’s perspective, the qube either has no microphone at all attached, or it appears to have a microphone that always records silence. If the first option is chosen, attaching and detaching the microphone should act as if a USB microphone was plugged and unplugged, respectively.

Actual behavior

To the application, the qube appears to have a microphone that is broken.
