problem with audio interface (MOTU)

Hi guys
i’m using motu 828mk2 with cubase 9.5 pro

when i hear a sound through another application (for example firefox, youtube, splice etc.) and get back to cubase project, cubase’s sound so weird.
like distortioned sound, or clipping sound. (not clipped at all)

I think i should set another output for cubase.
but my cuemix fx’s output fader is not working.

how can i fix this problem?

thank you

Hi and welcome,

Could you try to increase Audio Device Buffer Size?
