Research direction
Start with the OBS Studio log at https://obsproject.com/logs/eA5yOFOWssl40SUe and reproduce the issue using CamLink or Blackmagic Design Decklink audio through the ATEM setup described. Compare the macOS behavior with the provided normal and garbled audio samples and the unaffected applications; done means the capture audio is no longer crackly or muffled on macOS.

Expected Behavior
Audio to be provided properly. As per the file at https://drive.google.com/file/d/1mH0idrllqSLz0dMCAz7FiAb7_qiyRk85/view?usp=sharing
Current Behavior
Audio sounds extremely crackly and muffled, as per https://drive.google.com/file/d/1srPW2FnFX72FUagIzmpOYGzDNtdy4hS1/view?usp=sharing
Steps to Reproduce
- Set up CamLink or Blackmagic Design Decklink audio input
- Play audio through the ATEM (in my case it's a file on a HyperDeck being sent to the ATEM Mini Extreme ISO. The ATEM picks up the audio fine)
Anything else we should know?
OBS for Mac is the only software affected. Trying this in StreamLabs Desktop for Mac, OBS for Windows, or Audacity for Mac, all produce normal audio.
