I'm having a very similar problem. I just upgraded my laptop (a HP
Pavillion dv5000 with HDA Intel sound) from Feisty to Gutsy. It has
three keys above the keyboard to control sound (up, down, and mute).
Clicking the buttons doesn't affect the volume of the sound coming out
of the speakers. Playing with the volume applet also fails to change the
actual volume (application-specific volume controls -- the one in Totem,
for instance -- work fine, which I sort of expected).
I know that the OS knows about the button clicks, because graphically
it's doing what it always did (volume bar comes up in the middle of the
screen).
I can still control the volume by playing with the PCM channel.
Here's the same information the last guy gave.
