sound problem with Mimby v2 / Loki Mini

Actually, I've my Mimby v2/ Loki Mini eq/ Eitr mound running thru a small double-edged RCA in/ 1 RCA product switch (this comes after removing the bigger Little Bear MC-3 I was using to run balanced thru my Loxjie P20. My other papa running thru the switch works fine with no issue, so I mistrust it’s the switch itself. I was having to replug the coax line into the Eitr itself when I was using the Mc-3; with that trick, it always worked for some reason.
Now I ’m getting no sound with the Mimby at all.I ’ve changed coax and USB lines, harbors, checked all connections in back, made sure bitrates were matched, etc and nothing seems to fix it. Anyone presently have any idea what the issue might be? Cheers!
