Problem with ALSA

Hey, how things going....days ago I asked some info about a trouble about ALSA and my Gentoo Linux, the trouble was that I have the module for my sound card but simply doesn't sound.
I tried everything, and still I have no sound. I have and SIS AC'97 card. The KMix show the card and everything but nothing happens.
Then I see the ALSA Mixer, but instead of the name of my card, simply says "Dummy", does someone knows that if this is the problem? if there it is, how can I fix it?

Thanks dudes :)

Have you tried running alsaconf from the command line, to configure the soundcard first? Any errors or anything?

Yes, I run alsaconf and there is my card, then alsaconf configures it "normally" but when I want to change the sound values using alsa mixer, appears "dummy" in the cards name :(

Here, I put a picture about the alsamixer conf, give it a shot:

thanks

Well, when you ran alsaconf, did you happen to get a look at which module it is trying to load for your card?
Can you post the output of
lspci |grep Audio

This is the output of lspci:

00:02.7 Multimedia audio controller: Silicon Integrated Systems [SiS] AC'97 Sound Controller (rev a0)

When I run alsaconf, this is the information that is show:

snd-intel8x0
intel8x0 Silicon Integrated Systems [SiS] AC'97 Sound Controller
Now ALSA is ready to use.
For adjustment of volumes, use your favorite mixer.

Have a lot of fun!
but, when a tried to change the values of the card, appears this:
Picasa Web Albums - blacknightawake - Manuel Josue ...

:(

Ok, try the dmesg command and see if there are any errors about the soundcard or snd-intel8x0.

There is a lot of lines if I run that command, there is a way to see only the "sound" part?

This is the last part of the dmesg | tails command:

ACPI: PCI interrupt for device 0000:00:02.7 disabled
