Static noise on cross dissolve

Hello,

I'm doing a cross dissolve between two clips.

Without the cross dissolve the audio goes cleanly silent and then the new clip audio starts.
When I add the cross dissolve, then there is a static(y) sound during the cross dissolve.

I can't figure how it gets there?
I've tried changing the cross dissolve to 50 frames and down to 6 frames, but it makes no difference.

Any ideas why this is happening?

I've included a screen shot in case it helps.

What specific version of Resolve?

Version 16

Adding a system spec to your signature helps others assist:

There are many versions of 16. (That's why I asked for "specific" version. )

Turn off “Show all frames” for this or turn on render cache.

16.2.7.010

OK.

What camera was used to record the footage?

What's your hardware setup for audio?

Are both the system and Resolve set up for 48 kHz audio?

Hi @Tom Roper,
I think that's what is causing it.

How do I turn off "show all frames"?
I don't see that setting for the transition?
