MUTED AUDIO Resolve Studio 20 Public Beta 4

I am doing 4K 30fps and while editing, some files will become muted, no M showing, not meters moving but I can see the audio waves. it will play audio from the media folder in resolve. It seems when I split a file the audio will come back on the later file but the previous file is still muted. I did do restart and is seemed to solve the issue but after a few minutes of editing it muted the files again.

The audio meter does not show anything when the file is muted, if I slice the beginning of video file it will play the audio after the slice.. Definitely new to DaVinci Resolve Studio 20 Public Beta 4 that I updated to today.

I did notice when I lower the level of an audio track to muted levels that WILL play, the adjustment has no effect, it still plays the audio.. when I restarted the computer that part of the edit where I lowered the audio did lower to mute levels properly, but then the muted issue came back as I was editing.

What is the codec?

With the BRAW muted audio bug you don't have to restart Resolve, merely close and reopen the project.

I have same problem even after upgrading GPU driver. For right now, I'm keep re-starting resolve app. I hope this is not my computer problem.
