I'm having problems with the Komplete Audio 6 Mk2, it might be after updating to MacOS Sequoia.
The outputs on the unit are working fine, but when I plug an audio jack in to either input, the sound is really glitchy/bitcrushed/almost vocodered. When i plugin the microphone via XLR to the same unit, it seems to work fine.
To isolate the problem, I tried the unit on another mac (running Sonoma 14.6.1) and the inputs worked fine.
