Thanks for pointing out the other bug. I'm always setting the audio input by
hand so I had not noticed.
About this one, I didn't know what to do about the audio selection since now
there is an extra line-in selection which is internal line-in (input 3) so it
would have to be selected when using video input 1 (svideo2) and 3 (composite
2)
I think it would be much clearer if the cx25840 was exposing all inputs it
could support and was not aware of the wm8775. It should also not be aware of
different type of cards. That should be reserved for a pvr150 section of ivtv
that would interface with the cx25840 module.
