Hi! I just upgraded from Ubuntu 19.04 to 19.10. The upgrade went mostly smoothly, with the main issue being a problem switching Chromium to the snap package version. Anyway, after rebooting, I noticed I wasn't getting any audio at all. After some internet searching, I found a post that suggested adding my user ID to the "audio" group. Doing this solved my audio problem.

Question: why would I need to add my user ID to the "audio" group? I never had to do this before.

Here is my audio device:

01:05.1 Audio device: Advanced Micro Devices, Inc. [AMD/ATI] RS880 HDMI Audio [Radeon HD 4200 Series]
Thanks in advance!
