Comment 326 for bug 1801540

Updates on this long endeavor as of today: I choose to give another try for switching from PulseAudio to the PipeWire sound server.

The problems are completely gone. No audio clicking anywhere on the system.
I have tried one month ago, but on reboot I was not having any audio coming out from the system. Now everything worked on install right from the get go. Tried also the mic under Steam, which always had audio clicking issue while acquiring and audio stalling (don't remember under what condition); acquisition is now perfect. Tried to dual test recording from Steam Voice and Discord while playing audio, no delay, no crackling, no issue. All streams are working simultaneously. I still have not long tested this, by the way, but on a first impression, yes, it fixed a lot of issues for me.

The only minor configuration issue was to switch the microphone detection method in the PipeWire configuration file, otherwise no microphone were detected. After that, everything work as it should, for now.

The issue on my end was definitely PulseAudio. If you still have problems, try PipeWire if you can or if fits your needs. This definitely solved my problems, maybe it will help yours too.

Marco.
