Audio either not working or dropped to -55db

situation is that all audio to my stereo out is not registering on the meter and thus no sound, or is minute and around -55-60db.
i mix into a submix and everything is routed to this submix, which is routed to my stereo out. i use control room so my audio outputs in output are ‘none’ and in control room they are set as always they have been to my Apollo Console virtual channel. Suddenly this situation is occurring. one confusing aspect is that media bay audio ‘‘is working’’ but there is no signal at the stereo out level, but that it’s going direct to my ‘console’ (uad). Studio/Audio and Studio / Studio setup are correctly set up as always. could there be something that is preventing the signal from my project getting to my stereo out.

And is “everything” showing a signal at this point? If you go step by step following a signal through your routing, at one step you presumably have a signal and at the next step you don’t. Can you identify where that happens?

I’d first look for Insert plug-ins with its output set to 0. Or maybe a Channel’s Pre-Gain is turned down.

raino…thanks for the tip…i just got back into the project. issue was pregain but it was on the stereo out channel…it had defaulted to infinity on ‘render audio’…so when i went to make my mix render it knocked out the stereo out volume…i had no experience to think that this was the issue. you can be assured i’d tried every other thing…but all the metering heading downstream was solid…until that final stereo bus…problem solved…but your reply gave me the ‘clue to go looking’ appreesh man.
