/*
* "unmute-ozonic" by Mark Brand (orania), based on "test-enhanced-mixer" by Daniel Wagner
* This is a knee-jerk reaction to the pathetic situation of requiring a dual-boot setup
* for the sole and only purpose of unmuting the outputs of my M-Audio Ozonic. Seriously!? ;)
*
* This utility requires patches to avc_function_block.cpp and bebob_function_block.cpp
* which might be problematic for other devices? I've included my patch to tests/SConscript.
*
* Also had a preliminary go at the mixer, which seems to work... but is incomplete.
* All were originally based on revision 1957, though everything works for me under 1985.
