I'm having the same problem on ASUS X71A notebook (Ubuntu 8.10 kernel 2.6.27-7-generic, Intel Pentium T3200 (core duo) )
System->Preferences->Sound->Sound playback: HDA Intel ALC622 Analog (ALSA) -> Test shows the folloing error message: "audiotestsrc wave=sine freq=512 ! audioconvert ! audioresample ! gconfaudiosink: Could not open audio device for playback." No mixers are muted, yet no sound.
