I believe this problem should be solved now…
First thing to try… Have you cycled through all the volume levels (Main Output & Master Volume)?
2nd thing to try that fixed it for me.
Vayner from the beta forum suggested to connect Push to the computer as the primary interface and then check the output levels.
Mine were extremely low. Bringing the Analog Outs 1/2 to 0.00 db fixed the issue.
I now have the inputs set to Instrument In and can freely adjust the In Gain on OTO boxes as needed.
Hope this helps. Here’s a screenshot of how my levels were before adjusting on the computer:
AND… don’t know if. you see this, but you can change clock source on Push to ADAT, making it much easier to use the 18i20 as the primary clock.
