headphone sound.

[Robin <funky_cheeze@usa.net>]

I was wondering how it'd be possible to redirect audio out through my 
headphone jack if I had something plugged in, or simply how to switch to 
them.  I recall an old kernel... 2.2.17 or so (from YDL1.2) only sent 
sound out through the headphone jack, so I assume this isn't impossible. 
System is an iWhack DV; AWACS sound, kernel module is dmasound_pmac, 
etc.  Someone told me once that it's simply a matter of adjusting values 
using aumix, but I've had no luck.
