no audio after minor settings changed

Public Beta 2
Windows 10

DaVinci Resolve -> Preferences -> User -> Editing -> Standard Still Duration

When I chyange this value to 2.8 I loose audio. In fairlight I don't even see the volume bar moving.

If I change it back to 5 sec everything is fine again.

Worth mentioning: after setting a value of 2.8sec, stills are being put into Timeline in this length. Everything works fine, except the audio.

So it's definitelly a bug.
