Actual behaviour

Audio Output + Input stutters when using a class compliant Native Instruments Komplete Audio 6 on macOS.
Maybe this has something to do with the audio buffer size being to small? I also don't see an option on how to configure the buffer size.

Edit: If I change the sampling rate from 41 or 48 kHz to 96 kHz the crackling seems to go away.

Expected behaviour

No crackling/stuttering.

Steps to reproduce

  1. macOS
  2. Komplete Audio 6 via USB
  3. Set sampling rate to 41 or 48 kHz in Audio Midi Setup
  4. Run UltraStar
  5. Listen to background music

Details

Provide some additional information:

  • Operating System + version: macOS Big Sur 11.2.3
