MP 5.1 audio input not working?

Hi guys,

I am trying connect external microphone (3.5 jack - Apple 669-5103-A and 669-5098-A) to my MP 5.1 (analog input) but no luck :( I try both on my mbp and I can confirm that both mic's working.

If I connect my iPod to line in it's working.

Is there any option how to switch line-in to mic-in ?

I am using OpenCore and macOS Monterey but I don't think that this can be any issue.

Thanks a lot for any advice/ideas.

Nothing ??? No ideas ???

The input on the MacPro is line level only - there's no wiring to power a Mic like the old iPhone 3.5" headset.

Hi @roboscrap

On your Mac have you tried booting into a older version that is natively supported as these sorts of issues can appear on some devices

Also have you tried looking for any custom drivers for the mic?

Hopefully this helps

Any questions please ask

Thanks:-)

I don’t have any spare SSD at this moment as I am trying get macOS 13 on my cMP :) so can’t test any supported macOS at this moment :(

I will check custom drivers :) but both mic’s are from 1991 :D so not sure if I can find anything.

Thanks a lot.

@roboscrap

If the mics are that old you may need to plug them into a desk(audio interface) for them to work
