[HDA Intel, playback] mute button does not work

[Christoph Buchner]

I got an HP8530w laptop. Up until Oneiric, the hardware mute button (actually a touch-button) was working as expected. With the upgrade to Oneiric (I think, I use it seldomly), the hardware button stopped muting/unmuting. It changes color, though, as if it worked. The touchstrip for volume control still works as expected.
Any further info needed?

Is there anything more I can do to help here?
