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?
