No sound whatsoever.

Running Fedora Core 6 on an Asus z35f. This is similar to the System76 Darter series. Currently kernel 2.6.20-1.2933.fc6 (running x86_64 kernel), fully updated system through yum.

Here's the full output of lspci:

At the very end of dmesg I get this:

If anybody has some thoughts, I'd be grateful!

Two things to try:

Make sure your modem is enabled in the BIOS (this can prevent ALSA from properly determining the model of the sound system).

Try adding the following to /etc/modprobe.conf:

options snd-hda-intel model=3stack

You can try also:

options snd-hda-intel model=laptop-eapd

that works with my Asus (V1J) but I had to play a little with volume and mute/unmute options on alsamixer.

Huh. After following macemoneta's advice and adding model=3stack to modprobe.conf, it works! Weird. Guess the autodetection needs some more tinkering.

Anyway, thanks for the advice, guys! This has been bugging me for awhile.
