Hi Teej and thanks for reporting this bug. Is this still a problem in the latest Natty (with a 2.6.38 based kernel)? I've been running the codec in an emulator and the speaker seems to mute properly there.

I don't remember filing this, might have been on the laptop I got rid of, so closing bug report. Thanks :)
