I have some additional information add on this request.
When the sound "disappears" in Mythtv it first gets squeeky and
distorted, like a fast forwarded clipped chirp, and then the sound goes
out.
The eror message below actually occurs when either beginning or ending a
recording after this occurs. There is no event in the log.
The condition is fixed by unloading [rmmod ivtv] and reloading [modprobe
ivtv]
This condition occurs in mplayer [mplayer /dev/video0] as well. In
that case, there is not a chirping to the sound as it goes out, it
happens more abruptly. Mplayer begins to complain of
Too many packets in the buffer
Maybe you are playing a non-interleaved stream/file or the codec
failed?
By the way, this happens with two different computers, but I have not
been able to try a different Hauppauge card.
