I was running just 2008.8+updates, I tried the command you suggested but 
is didn;t make any discernible different.
Just to be clear, I'm trying use common-or-garden 3.5mm stereo headphone 
to listen to mp3 audio.

Alsamixer wizardery aside, I'm most curious as to why rotating the plug 
into the FR changes the audio at all.

I'll try a couple of other builds...
