Here's what I do after a fresh reboot: Change "input source" from "mic" to "front mic" Turn up all recording mixers to 80%, including "mic boost" and "front mic boost"

OK. Just to be sure, could you try % arecord -fdat -c1 -vv foo.wav ?? Also, attach the alsa-info output during recording with the internal mic.

Is it possible, that the mic is not really connected with the vt1708s, but rather linked to the internal webcam (which is not working at all btw)?

Hm, not impossible, but I don't guess so. The webcam is usually a usb device, and the vendor doesn't do a complicated wiring.

That would explain, why I still get a peak from the external mic-in, even when I set the input-source to "front mic".

Thanks for your great help with the unstable-snapshot. Did you actually write the fix, or was it available all the time? (I thought about using the unstable-snapshot before but didn't)

I wrote the fix shortly. You can see two commits in http://git.kernel.org/?p=linux/kernel/git/tiwai/sound-2.6.git;a=shortlog;h=f...

BTW, the patches are now in the normal sound tree, so you can use alsa-driver snapshot (no unstable version) from now on again :)

thanks,
