Hi Daniel,
Aggregated audio interface should work perfectly.
I am more thinking of a audio feedback inside Logelloop or from the input and output.
Inside Logelloop, this is possible if, for exemple, you send audio from aux 1 of fx 1, this is permitted in Logelloop 5 and may result to a feedback loop that can stop the audio scheduler.
Please, take a screenshot when this issue happened.
If you don’t find the solution, I think we may connect with teamViewer and look at the situation.
Sorry for this inconvenience.
Philippe
