Here are my settings:

 > sysctl hw.snd.default_unit
hw.snd.default_unit: 0
 > kldstat
Id Refs Address            Size     Name
  1   22 0xffffffff80100000 d71088   kernel
  2    2 0xffffffff80e72000 75638    sound.ko
  3    1 0xffffffff80ee8000 24e48    snd_hda.ko
  4    1 0xffffffff81022000 3a1f     linprocfs.ko
  5    1 0xffffffff81026000 1c4e8    linux.ko
  6    1 0xffffffff81043000 7ee      accf_http.ko
  7    1 0xffffffff81044000 1e6      accf_data.ko

kldstat numbers 4 - 7 aren't relevant, but my workstation had an option 
to choose the driver from a list and one chice supported earphone and 
speaker jacks (the Gateway has a speaker/microphone jack on the front, 
and the "usual" 3 sound jacks on the rear).  That optin was in the 
system settings ---> audio in KDE4  Gnome probably has an equivalent.

My /boot/loader.conf

 > cat /boot/loader.conf

kern.ipc.shmseg=1024
kern.ipc.shmmni=1024
sem_load="YES"
sound_load="YES"
#snd_ich_load="YES"
snd_hda_load="YES"
#snd_emu10k1_load="YES"
#snd_emu10kx_load="YES"
loader_logo="beastie"


The commented out entries are evidence of my futzing around with the 
workstation before I finally got the sound to work.   The first 3 
entries (and the last) in my /boot/loader.conf  aren't sound related.
