After connecting my USB-C EarPods to the front ports of my Mac Studio, the internal microphone disappeared as input option from the system permanently (visible neither in the menu bar audio selection nor the settings app) even after disconnecting the EarPods.

Attempts to solve the problem by

Disconnecting the EarPods and• all other cable connections

restarting the• MacStudio

killing Core Audio with • "sudo killall coreaudiod"

did not fix it.

I no longer have access to the internal microphone which also makes it impossible to use an external microphone connected to the read audio jack port.

Sorry to be nit picky on your wording

But neither the 2022 nor the 2023 models appears to have a Builtin Internal Microphone

That is left to External Microphones

So I am not sure one will find an Internal Microphone listed in System Information >> Hardware >> Audio

Using an external mic with Y splitter cable or EarPods worked fine for me until the input source disappeared.

Perhaps it is the audio mini-jack. I would imagine you would need a TRRS plug on your microphone to make it work. There is a YouTube video using a Y-cable with iPhone connect to one end and TRS microphone plug on the other side. It has to be recognized as a microphone to show up in the Sound settings. The inputs and outputs are dynamic. Unless it detects there is a microphone on that jack, it won't show External Microphone in the settings.

It could be a dust bunny in the port. If you have some low pressure air you could try blowing it out.

I don't think the headphone mini-jack supports audio in.

It's listed as a Headphone jack, not audio in/out. Everything I can find on Apple articles and other forums indicate is has no input capability.

It does. I've been using it with an external mic up until now.

Weird. It seems no one else on the internet thinks it can without some third-party intervention.
