Your using the wrong driver. the one you want is snd_maestro3. Add
this to your loader.conf file:

#sound_load="YES"        #PCM Sound Support      
#snd_driver_load="YES"  # Loads every sound drivers it can find
snd_maestro3="YES"     # Your driver
hw.snd.maxautovchans=4 #sets up up to 4 virtual audio channels on demand
#hw.snd.targetirqrate=36    # read the sound man page
#hint.pcm.0.buffersize="16384" #read the sound man page

After you do that reboot and retest it. first thing is to check dmesg.
dmesg|grep -i pcm and do the same for ess and maestro, you should see
that it was detected. also you should try
'cat /dev/sndstat'. fire up X and well, anyways.... if everything is
working put the driver in the kernel config file and comment it out in
loader.conf. I'll see what I can do about your other questions later,
right now I need a smoke and have work to do.
