[Kwintv] Fwd: kdetv sound problem and possible reason

[George Staikos]

Maybe someone on the list can help?  I have not done any V4L2 work since 
everytime I do, the API immediately changes on me again.  I do recall syncing 
the card mute status with the sound mute status in my original implementation 
of the driver, though.

Hi,
I have Avecs SmartTV card (it's using kernel driver saa7134) which is working
fine with xawtv but with kdetv there is not sound. While searching for
reason, I've found that this driver is muted by default (according to dmesg
output with audio_debug=1) and probably kdetv don't unmute it (only alsa
channel). I've tried to recompile saa7134 driver to be always unmuted (with
hardcoded values) and the sound is ok, but this is only a dirty workaround
for this problem...

In sources of the driver there is some control value V4L2_CID_AUDIO_MUTE, I
guess that it's connected with that...

I'm using kernel 2.6.6-bk2. (with bytesex.org patches applied, but without
them is doesn't work too).

Sorry for my english.
