ATEM Mini Pro Voice Over and Music Clash

[marekstycos]

We have the ATEM Mini Pro, an external mic and one stereo audio source.

The rig performs perfectly with OBS streaming to whatever platform (Youtube, FB...).

But will not with Zoom. There is a three second delay when stopping the music and speaking where the mic is inaudible. Also cannot be hear over the music.

Using a Sound Devices MixPre6 solves the problem, but the ATEM is purported to handle all this, so why need more hardware?

No DSP is activated (gates, compressors, limiters...)

Both Zoom and ATEM are up to date.

"Original Sound for Musicians" is selected in the settings and in the top left corner of the active Zoom.

High Fidelity Music mode selected

Echo Cancellation off

Stereo audio selected
