[e-users] Puzzling issue with the mixer

[Jesse H. <je...@ph...>]

Hello,

My mixer module doesn't seem to be working.  For instance, using the 
usual volume up/volume down buttons shows the popup indicating that the 
volume is changing, but no change in sound.  Some investigation shows 
that there is an odd setting in Mixer Module Settings.

Mixer to use for global actions:

(X) (null):(null)

Obviously, that isn't right.  How can I fix this and point it to HDA 
Intel PCH:PCM or something similar?

NOTE: All of the usual output streams appear when I look at the mixer 
applet settings: Beep, Headphone, etc.

Pardon me for not giving version information.  If someone will tell me 
how to find that info, I'll give it.  Thanks.
