Ya that too. I had not thought of the possibility that pulse clients might 
be a part of this... but aside from tweaking more than one control on the 
alsa side, pulse also has a gain stage of it's own. Pulse's levels can be 
changed by the client program which may not seem like a big deal... except 
for programs like Skype that use these levels for AGC rather than their 
own gain stage. This means the pulse level while using such a program may 
change on it's own depending on room noise for echo/feedback cancelation.
