Hi,
I recently bought a Terratec Grabby. The device has a S-Video and 3
Cinch
cables (sound left, sound right, video). I want to record some video
cassettes with it. (with a cinch-scart adapter).
I checked the signal, there is audio and video on it.
When I try to "play" the capture device with e.g. mplayer, I see "no
sound", even with various options.
I can hear sound only by doing "arecord -D hw:2,0 -r 32000 -c 2 -f
S16_LE |
aplay -", but as soon as mplayer is starting, I can't hear anything
anymore.
...which means that using alsa as the sound device with mplayer doesn't
work either.
Am I missing something?
I checked the source code, Terratec Grabby support was introduced with

Is there maybe a wrong amux set? Which one could it be?
Is sound-usb-audio somehow conflicting with em28xx module?
I hope you have an idea what is wrong here!
