I got the UltraStudio connected via SDI to the ATEM to play VTRs and lower thirds through vMix.
For some reason everything I play has an audio echo. Or rather a delay that doubles the sound (video.works.fine though).

vMix plays out master audio to the UltraStudio. Headphone monitoring is assigned to the Realtek onboard chip.
I tried changing settings in vMix and in Windows and on ATEM software to no avail.
Audio comes out just fine on headphones or laptop speakers so it is something to do with the UltraStudio I just can't figure out what.

Any ideas?

Having the exact same issue.

Hoping you may have found a solution?

For anyone else who faces this in future...

I had the Ultrastudio set as 'Master Output' within Vmix Audio Output settings.

This was then duplicating when the Ultrastudio was set as External output.
