Topic: UCX Audio dropouts / glitching. MacOS, 4.07, v49. Mac Pro M1 16"

I've had audio dropouts for YEARS with this audio interface. Small little glitches (when using any audio software, including Spotify / Youtube / Ableton / Bitwig) that haven't ruined things till recently.

Every driver upgrade or Mac upgrade I hope it'll go away, but in fact they've gotten worse recently. Now making listening / mixing really annoying as they happen often and are half a second long.

I have no such issues when using the internal interface with speakers or headphones. Only thing I've noticed that helps is a complete reboot of the system, but the return after a while. Seems like internet busy apps like Dropbox can also affect it, so I've taken to quitting those when mixing or performing.

Really been driving me up the wall recently! Love the performance of this interface in every way apart from this glitching!

Has anyone found a way to fix this? Might switching to a firewire cable help? (Would be firewire -> USB C adaptor with this Mac)

Hello? (echo, echo)

It's still not clear what the exact cause of the issue is, but this is something to do with the M1/M2 CPU, and it affects a lot of USB interfaces (not just RME). The same OS on Intel hardware has no such issues.

Using FireWire thru Thunderbolt would indeed bypass the problem and I expect it will be working fine for you.
