Zoom separate recordings failed

[thelostlibertin]

Hey all, 

I frequently use zoom to record a podcast I work on. In recent months the separate audio feed is often failing to record the participants correctly. The separate audio recordings sound like there has been significant connection issues... while the compiled, combined audio sounds fine. I have a large chunk of free HD space and there are no other operations taking place on the computer at the same time. 

Any idea what's causing this problem?
