 The above mentioned device doesn't support dma-sound(cx88-alsa), so is
 cabled to a soundcard.
 While it works everywhere, although the soundcard aux port gets regularly
 muted, sound disappears completely with mythtv.
 In v4l2-ctl I see a mute and volume control, but they have no effect both
 in mythtv and elsewhere. Obviously they are for a not present dma sound
 channel. I see mythtv unmuting on opening the device and after about 1
 second of sound through the cabled soundcard, sound disapears. On the
 recording there is no sound at all. On closing and opening the same
 happens.
 Obviously mythtv closes the audio-cable connection, assuming it opens dma-
 audio, which doesn't exist if pci subid is 8800.
 I haven't jet found how to close and open the cabled audio port.
 I am running latest stable 0.26 through gentoo with kernel 3.10.25.
