I did see those when I tried the 3stack mode, but in my current fix 
(modifying "ref" with my pin configs) I don't get such options in the 
mixer.  Any idea what I would need to do to get it to add these switches 
to the mixer?  This is the output from "amixer controls"

numid=8,iface=MIXER,name='Master Playback Switch'
numid=7,iface=MIXER,name='Master Playback Volume'
numid=13,iface=MIXER,name='PCM Playback Volume'

Thanks.
