Hello, I have currently have a (Grabster AV 350) [https://www.terratec.de/details.php?artnr=10599&lang=en] (and 300 that work even less but I will do another thread for it I think) I can easily get video output out of it with /dev/video0 but the problem is that I can't get audio by any way I looked a lot on internet and some peoples have the same problem... some of them has sucessfully fixed their issue by setting modprobe card=67 instead of the default 68. witch doesn't work for me! I do have the card that shows on alsa and pulseaudio but there is no sound (it's not muted, I checked) this really looks like a kernel issue (even tho i'm not an experienced linux dev) but I really don't know kind of info I can give you to help!
