I am running RELENG_7 from 12 Jan, I noticed that I am only getting 
sound on 1 channel. Also opening up "Volume Control" from Gnome and 
altering either of "Volume" or "PCM" produces crackles on the non 
functioning channel, and kills susbsequent sound output on either channel!

(Just to be sure I tried the speakers out with another machine, and they 
work fine - both channels)


I have hw.snd.maxautovchans=2 set in /etc/sysctl.conf - I'm wondering if 
that is wrong these days.
