I upgraded a VM running native Sid + Buster and did a full upgrade, and found audio with Mumble 1.3.0+dfsg-1+b1 via pulseaudio worked fine. I tried using ALSA with Mumble, and was not able to get that to work with the "[default] Playback/recording through the PulseAudio sound server" setting, and haven't tried further settings (yet). I tried OSS with Mumble and was not able to get that to work, but that didn't surprise me. Concerning Debian Sid/Unstable, my understanding is that it is not a complete distribution, and so Unstable is meant to be run as Unstable + Stable, i.e. Sid + Buster. Looking at the distributions you're currently using I see it's Unstable + Testing, i.e. Sid + Bullseye. I'm not sure if that may explain this bug or not; I may try to take a VM snapshot and upgrade to Sid + Bullseye and see if I can get the audio in Mumble to crap out. But for now I'm marking the severity of this bug as "important" rather than "grave" because as best I can tell it's broken on your system but not others. [If other users hit this bug when running Sid + Buster, please report that to this bug.] It's also possible this might be AppArmor related, because Mumble doesn't ship an AppArmor profile at the moment, and I see you've got AppArmor enabled.

There are users in the IRC channel that regularly help with PulseAudio issues. Similar to your experience, for me PulseAudio is mostly a "magic" thing which I tweak a bunch to get what I need if I find I need something specific. I'll try to be more help if I can. -- Chris -- Chris Knadle chris.kna...@coredump.us
