I seem to remember from your earlier posts that you assumed
that the "N" key switched which tuner card is used for the
fullscreen. As it turns out, "N swaps the two channels"
means the first card is always fullscreen and the second is
always PIP. Only the channels they are tuned to are reverse.
To test in myth, you should try recording two shows at the
same time to see if they both have audio. However, this could
be a slow process to test several times. "aplay" will tell
you immediately if you can read from the device the way myth
will read from the device. If things are right you should
$ aplay /dev/dsp1
Playing raw data '/dev/dsp1' : Unsigned 8 bit, Rate 8000 Hz, Mono
and hear the TV audio. If this fails I don't see how myth
could work correctly until this test succeeds.
Hope that helps,
