Audio becomes crackly/distorted after a few hours of recording on macOS

I'm using OBS Studio 32.2.2 on macOS Tahoe 26.5.1 on a 2019 Intel MacBook Pro.

During a long recording session, the recorded audio eventually became noticeably crackly/distorted. I believe this started after approximately 3 hours and 20 minutes of recording, although I don't remember the exact time when the problem began.

The audio was normal earlier in the recording and the crackling developed later during the same long recording session.

System:
  • OBS Studio 32.2.2
  • macOS Tahoe 26.5.1
  • MacBook Pro 16-inch, 2019
  • 2.4 GHz 8-Core Intel Core i9
  • 32 GB RAM
  • AMD Radeon Pro 5500M 8 GB

I am also currently experiencing a separate issue in which audio from a macOS Screen Capture source sometimes stops being captured during recording. I plan to report that separately, since I'm not sure whether the two problems are related.

I no longer have the OBS session open in which the long-recording crackling occurred, so unfortunately I may not have the relevant current-session log.

I'd appreciate any guidance on what logs or diagnostics I should collect if this happens again.
