I just put CM9 alpha 2 on my TP but I can't get sound through the speakers or the headphones, ever. The only thing that makes a sound is the alarm, so I know the speakers work.
If I go into Sound > Volumes, the "Music,video,games&other media" icon has a slash through it as does "Notifications". The "Alarms" icon has no slash, is lit up, and the volume works for that.
Is there a setting I'm missing somewhere?
[solved] Didn't know but if you hold down the power button there is master volume control at the bottom of the restart/shutdown screen.
