Grabster AV 350 no audio

[Debucquoy Anthony <d.tonitch@gmail.com>]

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! I asked IRC tho
