Hi,
I have Alsa installed on Beowulf along with Steam and I guess there is some Pulse stuff installed too. I also use Mumble to chat during game play. When I'm playing Valheim, I can get sound in the game, but Mumble doesn't work.

Is this just a mis-configuration on my end, or does Also not "share" the audio between applications?

I launch steam as the "game" user (using xhost+) to keep my regular home directory and files segregated from whatever asshattery might happen from game mods/applications/etc.

Maybe having two users access the Alsa sound devices is my problem? Installed Alsa/Pulse packages and Alsa devices are below.

Thank you!
