Couple of things to check:

* has one of the channels (e.g., master, PCM, front) been muted?
* has one of the channels (e.g., PCM, front) been set to volume 0?
* is the snd_pcsp module loaded?  (lsmod | grep snd_pcsp)  If so, unload 
it, and set it to not load in your rc.conf.  (That's been known to 
interfere with other sound modules.)
* are any of the "Analog Loopback" switches turned on?  If so, turn them 
off, as they can disable sound.  (I tore my hair out over that one for 
quite a while.)
