FaceTime on IMac 2019 external mic

[54 Les Paul]

Hi I'm new to this site. Please forgive me if this has been asked before.
I'm using a 2019 iMac with the latest Catalina. I want to use FaceTime with my Presonus digital audio interface and an external microphone. In system settings under sound I can select Presonus for both input and output. When I initiate a FaceTime session, I can hear to other person very clearly through my external speakers that are also being run through my Presonus, but they cannot hear me at all. The sound signal appears to be getting into the iMac but somehow isn't making it through to the other person. Any thoughts .... ideas???

Thanks
Rick

Is this a new microphone, or one you know how to use? Can you record into Audacity, for instance?

Jerwin, this is a system that I’ve used for recording live music for the last year. It works beautifully for recording to any DAW program.
In these times of self isolation I was hoping to set up a conference FaceTime call with some musician friends and do some virtual jamming.
cheers

Is the correct microphone selected in Facetime's video menu? Have you tried setting the microphone to a different sample rate?

Yes I can select the Presonus interface in FaceTime video menu. It is also selectable in systems settings. I don’t think I have a variable sample rate available to me that I’ve seen.

/Applications/Utilities/Audio MIDI Setup The format pull down menu should let you set both sample rate and bit depth. (Facetime handles 44.1Khz or 48 Khz) The channel volume may also be of use.

Thanks I’ll look at that. Volume is set at the Presonus interface.

So.... this is what I get . There is no option for me to control volume other than on the interface itself

sorry the image is so crappy, I don’t know how to take a screen shot.

what are the input settings?

The input settings look exactly like this only instead of DAW 1,2,3 etc. it says mic 1,2,3 and so on. The sliders are all greyed and I have no option to use them. Even when I’m using a DAW like Logic my input volume is greyed out and only controllable via the Presonus, but that works fine and I’m able to record multi track live music. It’s just FaceTime that I have this problem with.
Thanks for the link btw.

So system sound input, and midi audio devices input. It's linked through a firewire to thunderbolt cable but as I said it works for every other application.

Only thing that comes to mind is that video conferencing apps (like skype) sometimes use the first channel off a multichannel audio interface, and discard the rest.

If you still would like to use this...
Find the YouTube video called: Solved! Using a Multichannel Audio Interface with Skype

This method can be used for anything from Facetime to recording etc.

For Mac you will need Soundflower and LadioCast, but it works great for my online drum lessons.
