Hello,

I'm unable to run alsamixer:

$ alsamixer
alsamixer: function snd_ctl_open failed for default: No such device

What's happening? I do have sound, but not in xawtv.
I figured it might be a
My sound card is a intel8x0 chiptset, module snd_intel8x0.

I'm having tv card problems also...

I can get video but I'm unable to get audio output. The autodection of
my Pinnacle PCTV Studio/Rave is fine. For sound, I have an Intel 810
chipset. This system is sold as it is now, so all hardware should be OK.

$ head ~/.xawtv

freqtab = europe-west
mixer = /dev/mixer1:vol # this makes no difference, I'm unsure about this line
audio = stereo

$ xawtv
This is xawtv-3.91, running on Linux/i686 (2.6.4)

I read the Sound FAQ [0], but I didn't find an answer to my question.
I've seen that people have used this TV card in the past without
problems. At usenet, I read something about "you may need to
unmute line in', but I'm afraid I don't understand what that means.

Is it possible that it has something to do with ALSA?

Can someone help me?

Gerrit.
