I put a little effort in to capturing this issue when in Resolve:

I can confirm that 17B9 also audio glitches as well.

I had a very simple project, using H264 video from a camera one of our staff had for recording from home.

Happens within seconds of the voice over starting.

yes, it happens with nested timelines/compounds with more than one audio track.
A temporary workaround is to decompose the timeline

Aah, looks like there's been a few audio glitching posts recently, happening in the new update today too

Still experiencing this issue. It appears randomly throughout renders too. We're testing now if decomposing the audio portion of compound clips fixes it.
