Also impacting me on my HP DV6000t laptop. Muting the mixer using the mouse and menu options works fine.
Pressing the Mute button shows a Blue on Gray (HP-provided?) "Mute on" or "Mute off" message in the middle of the screen, but no muting occurs.

I believe it worked well at a previous version of Feisty. In fact, I'm positive it worked recently, because I only upgraded to Feisty a little over a week ago, and was amazed that audio was working completely (I used to have issues with the headphone jack in Edgy).

Thank you for your bug. Does using the mixer work correctly or does it has the same issue? What about alsamixer?

Closing this bug since no more information has been provided, feel free to re open it if you may get us the info we asked for. Thanks.
