Sum Mix and Pan
I'm trying to help someone who doesn't speak English troubleshoot their Sum Mix & Pan build. The current state of the module is:
Main L/R output lights always on
No sound from any channel, no LED response from volume sliders
No response to cv inputs
Photos are attached. To start, I've told him to clean everything up, Wick away excess solder, reflow, and clean the board. Orientation of everything seems to be ok
I'm wondering if anyone can spot any obvious errors.

No clean flux and thorough reflow save the day. The guy is really happy with the module.
