I’m using a Steinberg UR22 mkII USB audio interface with my 2018 Macbook Pro and I get random audio dropouts. I don’t have any crackling or glitches, just this 1 second break in the audio stream randomly. One or two times in an hour. Internal speakers are fine. It doesn’t matter what is the source of audio. Logic, Spotify or YouTube.
I think I managed to trace back the problem with Console. Every time a dropout occurs, the machine is fetching the current time from apple servers right before pausing core audio. I can even replicate the issue by changing the settings in Date & Time. Yesterday it happened right at 00:00 that’s why I started to suspect the clock sync feature. I disabled the set date and time automatically box in settings and so far I see no messages in Console about the paused core audio process and I didn’t have any dropouts in the past hour.
Can this be caused by the new T2 chip? If I know right, the T2 handles the audio in newer Macs.
I also read somewhere that since High Sierra, Mac OS is using a new method to keep the clock in sync and since this interface isn’t new, I wonder if there’s an incompatibility between the UR22 mkII and newer versions of the OS.
I’m on Mojave 10.14.2 since yesterday, had the same problem with 14.1. Tried different USB-C ports, using Apple’s official USB-C to USB-A cable. Using the latest available drivers from Steinberg (1.10.2). When I tried to use the interface without the drivers, I’ve got constant crackling in Logic, don’t know if this is relevant.
Update: Sadly, dropouts still occur even with the automatic sync turned off. I can still see the timed event in Console, and every time after it, there is a dropout in audio.
