Comment 101 for bug 192888

Given the warnings about real-time and high-priority scheduling, I added my user to the pulse, pulse-access and pulse-rt groups, then logged back in. This seems to have solved the stuttering issue with multiple sound sources.

I have noticed another very serious issue, however. When I adjust the sound via my laptop hotkeys, I get a visual indicator of the sound increasing or decreasing, etc., but no changes are applied to any of the mixers. Using the volume control applet works normally, though. I have never had this issue before, so I assume it's pulseaudio related. What can I do to troubleshoot this issue?
