I'm experiencing what I'm guessing is buggy behavior (or messed up configuration?) on a fresh install of Debian Buster. Symptoms:
- sound has always worked for user created at installation, "tedm" (Settings --> Sound --> Output always shows HDMI and Line Out and both pass speaker test)
- for user "test_maint" created with adduser, HDMI and Line Out work as for tedm after a reboot, but then, after some time (hours, not days) and/or switching users, sound breaks for this user only and "Dummy Output" becomes the only Settings entry
- occasionally, when logging in as test_maint, I'm faced with a GUI authentication popup about repository updates; usually this coincides with broken sound, but not always
- I say that everything works for tedm, but occasionally, after logging back in, I feel like the master volume or application volume levels have been reset

I may try adding test_maint to this group, but even if this fixes the problem, I'm wondering if there is a more standard way to correct things. Let me know your thoughts and/or what command output you'd like to see for system info, diagnostics, etc. Thanks for your help!
