Topic: Fireface UC stuttering audio

I have a Fireface UC, using with MacBook Pro (Retina, 15-inch, Mid 2014).  mac OS 10.14.6. Latest RME driver and flash update.

I occasionally get "stuttering" audio playback.  It's like suddenly someone put a delay on the output signal and it repeats ~1 second of audio for 3-4 seconds then stops.  It happens kind of randomly, some days it doesn't happen at all, on the other extreme today it happened 3 times within 2 minutes. 

I see that there are some other threads where users complain about stuttering but they are several years old.

Re: Fireface UC stuttering audio

Try all available USB ports. Also test with e.g. Wifi disabled. Which audio software is affected here?

Re: Fireface UC stuttering audio

I switched USB ports and it still happened.

Wifi however, that's hard to test, because I use the internet a lot unfortunately. I will try to keep wifi disabled and see if it happens again.

It's definitely happening with Ableton.

I believe it has also happened with Mac Finder audio playback and QuickTime (but I'm not 100% certain)
