I can see activity in the lights responding to program but nothing to send to youtube. I am reminded that back in the FLS days, I added a circuit trick where the feed to the FLS compound LTP came from the BP op amp outputs, but they had anti-parallel diodes in series with the op amp output and the actual BP filter NFB. This way they were two junctions hotter.
To use that trick on my 5v rail design would consume 2 diode drops of signal swing, from an already stingy 5V rail.
So... If it sounds good, it is good... and I can see some lights modulated, so I am happy...

[update- after living with this another day the loudest channel display is pretty universally indicating Front Left and Front Right as loudest, this seems normal for surround movie mixes, since you want the action localized up front, and surround effects are at reduced levels. /update]
