Has anyone used a universal audio Apollo to route multiple audio channels into a zoom call?

Greetings. 

I’m an audio and music producer. I’m trying to include multiple audio channels from a universal audio Apollo x6 in zoom calls. I am on a Mac Studio computer running the latest Tahoe, and using the latest version of Zoom.

My camera is an iPhone 16pro used as a continuity camera hard wired to the computer. Camera is working great. 

I have enable the multi-channel option in the zoom app,  but the only audio that appears in Zoom is the microphone channel on either channel one or channel two.

I have deep dived into all the resources for the audio interface (Apollo x6) , the manual for its console, the I/O matrix which controls how Mac OS “sees” the input and output channels, and several detailed videos on the topic. 

Nothing I have tried for days has ever resulted in any audio channels besides 1 and 2 to appear in the Zoom app audio settings input meter. 

Any help would be appreciated. 

Christopher.

As an audio and broadcast engineer I can tell you that computer audio can be very complicated. Zoom only accepts 2 channel mic audio. So any multiple channel source needs to be mixed down to stereo for Zoom. Also, stereo is only heard on laptops and desktops. Mobile devices and tablets will only get mono. This means you will need to reconfigure the thunderbolt connection for stereo instead of multi-channel  for a DAW. Be sure the word clock is set for 48K.

If this works please click accept as a solution.

Thanks for the reply.

With the Universal Audio X6, it works a little differently. I'm working on something directly with Universal Audio this week, but the idea is that you use the I/O matrix in the Universal Audio console to report any stereo pair to the computer as channels one and two. The matrix works at the driver level. 

I will share the solution here once everything is working exactly as expected.  Thanks again.
