[solved but still a mystery] soundcard suddenly stopped working

The onboard Intel HD Audio in my Arch machine was working absolutely perfectly until I turned off compiz-fusion. All I did was to delete the symlink in ~/.kde/autostart to fusion-icon & then restarted the machine. Now when KDE starts I am greeted by;

Informational - artsmessage
Sound server informational message:
Error while initialising the sound driver
device /dev/dsp can't be opened (Permission denied)
The sound server will continue, using the null output deivce

The permissions on /dev/dsp are;

lrwxrwxrwx 1 root root 9 2008-01-10 22:55 /dev/dsp -> sound/dsp

The permissions on /dev/sound/dsp are;

crw-rw---- 1 root audio 14, 3 2008-01-10 22:55 /dev/sound/dsp

I honestly don't have a clue how to go about fixing this, as the installer set it up automatically in the beginning without any input from me!

Update: it seems that sound works for root, but not my normal user.

Also, output of aplay -l for root & my normal user;

[root@yuzuki cj]# aplay -l

[root@yuzuki cj]# exit
exit
[cj@yuzuki ~]$ aplay -l
aplay: device_list:205: no soundcards found...

Edit: okay, so got it working thanks to some help from #alsa. I ran alsaconfig then rebooted & it seems to be working, but it's still a myster as to why disabling compiz would stop my user from hearing anything....
