No sound on my tv card

[ZaYer]

Hi, few days ago I reinstalled Gentoo again and for my surprise now I have no sound on my tv card.
I don't know why exactly, but it's possible that it could be Line1 is muted how can I unmute Line1 (no Line)?
Thanks.

Hi,

I you are using alsa, you can run alsamixer. Use the right/left arrows to move to the line, or aux (it's aux for me, but I think that it depends on the soundcard) and push m to toggle mute. Up/down increases volume.

Is the input gain up as well? Make sure that line or aux or whatever is capturing, too (space bar toggles capture).

That's ok, but I don't know why still doesn't woking.

Connect a headphone to the tv-card's sound-out - can you hear anything?

Doing that I can't hear nothing.
Other way I could hear something realy slow.

Okay, so the problem sits in the tv-card.

What modules are you loading for tv? Many cards need the msp3400 module for tv-sound. Do you load the tvmixer module? What's in kern.log?

Tow questions yes.
Here is my /usr/modules.d/tv:

alias char-major-81 bttv
pre-install bttv modprobe -k msp3400;modprobe -k tuner
options i2c scan=1
options bttv pll=0 card=6
options tuner type=5

And yes, I'm using tvmixer.

My tv card's chip is bt848, a Pinacle Studio PCTV card.

Hmm... the modules seem to be ok.
Is it possible that the tvmixer is muted or very low?
