files only play in preview-monitor

[Fungimaster]

Hello
some of my .mp4 files only play in the preview-monitor.
when i left-click the clip in the column then apears a bar in the middle of the clip and it does not play
i have this issue on my windows-computer. If i try to play the clips on my mac in the same projectfile , then it works without a problem.
I dont think that it is a codec-issue because i can play the clips in the preview-monitor of my windows-computer too. I attached a image where you can see the apearing bar.
please help me !!!!

It is possible this could be a bug that was fixed relating to audio interfaces.

I see you are running version 5.0.0
You should try updating to the latest version of Arena 5 and see if that fixes the problem.

Hi Fungi....
does is run when you disable beatsnap?

I would suggest updating to 5.1.4 so you're on the latest version.
