The fact is that Acer's speakers/headphone never worked with the test 
model. ;) They DO work now though, as the test model mixer has 
acquired more controls.

Well basically, if you get the internal speakers/hp jack to work, then 
it's autodetected. If you don't, it's not. Currently, no other model 
supplies initialization strings suitable for Acer. I don't know any 
other way to know which model has been loaded (I'd like to, though)...

BTW, one more thing to consider if you don't get the sound working is 
to rename/delete the mixer settings file (/var/lib/alsa/asound.state 
on Ubuntu) and then to cold-reboot the box (by holding the power 
button for a few seconds). After rebooting, the box should boot with 
the default settings for your model (which should be "acer"). At least 
for me, after Ubuntu automagically unmuted some channels and raised 
volume, the sound worked right out of the box.

You can still play them with VLC/Gnome CD player/Sound Juicer/whatever...

I hope it was.
