--- Comment #5 from Alexander Sieg <alex at xanderio.de> ---
I'm having the same problem on my t420s. It only started today, after working
fine for over 3 months. The Audio issue appeared after trying suspend on this
machine and even after a full restart and power cycle it does not go a way.

The issue only happens with firefox(8). Other Applications with use snd
directly don't have this problem such as cmus(8) and mplayer(8). It may be
pulseaudio related.

cat /dev/sndstat
