What you said, was:
Some applications like mplayer don't use V4L2_CID_AUDIO_MUTE to unmute a
device. They assume the current behavior that starting video also
unmutes audio.
"starting video also unmutes audio" is what my patch
_does not touch_! And that certainly happens not even
in the alsa driver, but somewhere in the v4l2 code.

So, please please please, could you actually precisely
explain how exactly mplayer breaks with my patch?
That's the only thing I need! :))
