I also have this problem on a recurring basis, but recently noticed something that could be interesting...

I started by putting a pre-rendered audio track (a WAV file) at the bottom of the audio tracks in the timeline. I discovered that muting the MXF's native audio tracks (Audio 1...Audio 2...etc) doesn't alleviate the problem. The WAV will still play back erratically. I have to highlight the MXF's audio clips in the timeline and then mute/disable them (with the d-key) before my WAV file will play back correctly.

I'm in Resolve Studio 18.1.2 on a Mac M1 Pro running macOS 12.6.2

Ahh, I totally respect you asking that, but I will alas not be getting permission to share the footage (and we don't own the cameras in question). It was footage from two C300s; a mk i and a mk ii and over several different interviews. Happens every year when we receive the year's material.

Internally, I've checked on an Intel Mac that we also use (with the same Davinci Resolve and macOS versions) and it's the same thing.

Any chance you could find some other clips from that camera online Andrew? Compare those to your own clips?

I have the same issue with Canon.MXF files from a Canon XF705. I get crackling when playing or scrubbing such clips. I think I've narrowed it down to an issue where the video portion is somehow interfering with the audio because if I disable the video track, the audio plays clearly. I de-activated all VSTs and AUs and my one video plugin,, quit and reopened and no change.

But this has only happened since upgrading to 18.6.4 so it suggests a bug on Davinci's side.

Any thoughts?
