It has been a while, but I thought I would give this a shot again. I bought this cable from Guitar Center: https://www.guitarcenter.com/Livewire/Essential-Interconnect-Cable-RCA-Male-to-XLR-Female-10-ft-Black-1500000013571.gc
I am still not able to get any sound. I have the Helix LT going to digital out. I attached my setting for the Focusrite 18i20 Gen 3. Do you think I should try the exact cable referenced from Sweetwater? It seems like the cable from GC is the same.
