Gerd,
I've just tried your patch for tvaudio, and it works fine on my FV2K.
Please apply.
This patch has the effect of unmuting audio in xawtv as soon as the
channel is enabled (and muting on exiting xawtv). So static will be heard
if the signal is really weak or if there's no transmission.
The previous case of using the tvaudio thread would keep audio muted if
there isn't a strong audio carrier. I guess unmuting only when a strong
carrier is detected is easier on the ears, though it might not be the
correct behavior.
I'll live with the static since at least I know tv audio is working :)
NB: the patch does not solve the problem of mplayer audio not unmuting,
but that is a v4l1 compatibility issue anyway.
T.C.
