 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
 4557af9c5338605c85fe54f5ebba3d4b14a60ab8:

 Hi Mauro,

 with the help of Bernd Spaeth, I finally managed to get the Terratec 
 Grabby
 working by using

 mplayer -v -tv
 driver=v4l2:input=0:device=/dev/video1:alsa:adevice=hw.2,0:audiorate=48000:forceaudio:immediatemode=0
 tv://

 and your patch

 Working video and audio!

 I wasn't able to test it with s-video, only composite.

 But I think it's still safe to commit the patch, because s-video is 
 only
 another video input, the audio output stays the same.
