..i have one PC that likes to boot with a few of the hidden audio channels muted.. I open kmix volume controller from the panel, click the mixer button, then display all channels and make sure none are muted and all are turned up.. this usually fixes my problem.
You might also check your sound settings in PCC under hardware > sound; by default it should have an alsa driver matching your sound card:
00:1b.0 Audio device: Intel Corporation 82801I (ICH9 Family) HD Audio Controller (rev 02)
..you can also try and enable PulseAudio by following Texstars directions here:

The classic bug sound tester is to run the following commands:
- "lspcidrake -v | fgrep -i AUDIO" will tell you which driver your card uses by default
- "grep sound-slot /etc/modprobe.conf" will tell you what driver it currently uses
- "/sbin/lsmod" will enable you to check if its module (driver) is loaded or not
- "/sbin/chkconfig --list sound" and "/sbin/chkconfig --list alsa" will tell you if sound and alsa services are configured to be run on initlevel 3
- "aumix -q" will tell you if the sound volume is muted or not
- "/sbin/fuser -v /dev/dsp" will tell which program uses the sound card.
