Version-Release number of selected component (if applicable): Firefox 23.0.1 How reproducible: always Steps to Reproduce: 1. log in into gnome session 2. open firefox, open youtube, play a video (not using flash) 3. switch to tty 4. log in as (another) user, e.g. root on tty 5. do something 6. log out on tty 7. switch back to gnome session Actual results: sound is instantly broken on switching back to gnome Expected results: sound should just "go on" like it does when playing from gtkwebkit-based browsers or totem
I guess it's because Firefox is using alsa backend instead of pulse audio.
Switched to pulse audio backend - see Bug 1010916.
