Try applying the following (untested) patch that is made against the
bleeding edge Linux kernel.  The test on the mute control state in
wm8775_s_routing() appears to have been inverted in the bad commit you
isolated.

Along with '--set-input', you may also want to use v4l2-ctl to exercise
the mute control as well, to see if it works as expected, once this
patch is applied.

Regards,
Andy

Thanks for the patch. Unfortunately, my htpc has been kicked off the
network when the attached TV died. It will take me few weeks to get it
up again. But I will try this patch when things are back normal and
report back.

Aargh! I'm pretty sure that's the culprit. Man, that's been broken for ages.
I'll see if I can test this patch this week.

Hi Hans,

Yes, and only *one* person reported it in those years.  I suspect very
few people use the comination of conventional PCI, analog video, and
SVideo 2 or Composite 2 anymore.

Thanks!  I'm very busy at work until mid-December.

Andy

I finally managed to test this and this patch does indeed fix the bug. I'll make
a pull request for this.
