Public bug reported:
Binary package hint: pulseaudio
When I adjust the volume using the new Karmic mixer in Gnome (or the
wheel on my keyboard), the sound comes out sounding tinny (A little be
crackly but mostly tinny)..
However if I jump into alsamixer and make even a minor change such as
turning the volume up then back down to its original setting the tinny
sound goes away. Changing using the Gnome mixer causes it to come back.
Sometimes it seems the problem seems gets temporarily fixed and the
gnome mixer doesn't cause issues until next boot (probably after laying
around with alsamixer for a while, haven't found out exactly what
conditions fix it).
I also notice that when adjusting the mixer, when watching in alsamixer,
the PCM, Front and Surround channels have small changes (if they are at
%100, then they tend to jump around 97-100). Also if I turn down the PCM
channel, the gnome mixer will turn it back up to 100 but turn down the
Front and Surround channels.
