1. What kind of microphone (and what kind of connections) are you using?

2. Please reproduce the problem again, and then immediately run this command:

   journalctl -b > journal.txt

   and send us the resulting file 'journal.txt'.

Thanks.

Your kernel log shows a lot of messages from Discord. I wonder is that app affected, and can you please try a few other voice apps too?
