Hey Folks

Wondering if anyone could assist me. Running Aurora 16 (w LT Madi card) into b80 Mothership (24 in /32 out). Hoping to run lynx and first 8 channels of mothership as hardware inserts and additional 24 outs on mothership to summing mixer. Having a heap of trouble getting first 16 channels into aurora and then remainder into Mothership in loop (using optical cable, have tried multiple cables) and also played with Lynx madi card dip switches to no avail). Have tried separate madi loops but PT decides it will 'unexpectadaly shutdown'. I am running less than 64 channels so hoping to use only 1 loop. Use of aggregate device in PT not possible as RME card is all that shows up as only running LT Madi card in Lynx. Any other ideas??
