Apollo x4 interface/audio dies repeatedly when in a session

[Mark Delsing]

I'll join group and be happily playing along, and then my Apollo x4 will audibly "click" and while I'll still be in the group, all audio monitoring will die — I can'r hear myself or hear others. I quit Sonobus, wait a second, restart Sonobus, hear my interface "click" again and audio come back, and then rejoin the group. I was in an hour-long session today and to do this maybe 5-6 times.

I don't think that this ever happened prior to 1.5.1.

Anyone have any insight?

I am running a guitar amp into a UA OX, then connecting it to the Apollo x4 via S/PDIF. I had the Apollo console set to 48kHz, converting the OX's native 44.1 output, so I'll try setting Console back to 44.1 and see if there's any issue there.

Update: As a test I picked up an MOTU M2 USB interface and used that in the situation described above, and it worked perfectly, so I suspect this is an issue with Sonobus and the Universal Audio drivers for Apollo x4.

I have crash reports available here: https://www.dropbox.com/sh/f9glsdyju8wdcbn/AABpOseP0C4JzSsDSQxcDxsMa?dl=0

If someone could get me in touch with Jesse, the developer, I'd appreciate it. I'd love for someone with some know-how to look at these reports and help determine the cause. The MOTU is an acceptable stopgap, but I'd prefer to just use my Apollo x4.
