Sound not working on an Intel 5 Series/3400

lspci gives me these two devices:

$ lspci | grep Audio
00:1b.0 Audio device: Intel Corporation 5 Series/3400 Series Chipset High Definition Audio (rev 05)
02:00.1 Audio device: ATI Technologies Inc RV710/730

There are two devices listed in System Settings|Sound|Output:

• RV710/730 Digital Stereo (HDMI)
• Internal Audio Analog Stereo

And finally, the are not muted!

Also, when I run an application that accesses the sound card, I can see it in the Applications tab.

Any ideas?

It seems that the new kernel update (3.0.0-13) solved the problem.

I am depending on a previous Launchpad q/a (last answer) [1] and suggest compiling Alsa. But instead of grabbing Realtek drivers (same as Alsa) just download latest files via alsa-project.org [2]. You need to download just alsa-driver, alsa-lib and alsa-utils packages. Pick latest ones which has 1.0.24 version. After that just compile the packages as explained there.

If you get an error about panelw library while compiling alsa-utils, just change the configure step as this:

./configure --with-curses=ncurses

I had the same problem. I solved reinstalling alsa modules sudo apt-get install --reinstall linux-image-$(uname -r)
