Only audio when scrubbing, not while playing.

i found this on reddit maybe it can fix your Problem:

Hi all - I was having a similar problem (no audio playback, bars moving, changing preferences, etc).

In the end I reset preferences and the plug-in cache, and (HURRAH!) got sound back.

These were the Adobe instructions I followed:

'...To reset preferences and plug-in cache at the same time, hold down Shift-Alt (Windows) or Shift-Option (Mac OS) while the application is starting. Release the Shift-Alt keys or Shift-Option key when the splash screen appears.'

You should get a box asking you if you want to reset. Click OK.

Hope it works for you!

The amount of crickets here are deafening...

Here you can see it properly recorded with sound and uploaded to Youtube: https://www.youtube.com/watch?v=7-UAFGdWegY

I'm at a loss here. I can't continue with my work now.

Also tried switching audio output.

It even gets weirder. When I move the playhead some seconds earlier in the clip, the audio does play. EVEN beyond the point where it wouldn't. But when I move the playhead back to the position earlier.... nothing. I can't wrap my head around this.
