Removing ground loops can be hard---especially when there are computers and networks involved.

But I think an easier solution is to use an audio transformer to isolate the systems.

The ones I was using were from Jensen Transformers

Rapco/Horizon (LTI-100) as they're cheaper and have actual balanced XLR
outputs.
