Microphone not being detected

My computer is a T430, checking the Input Device ‘pavucontrol’ is it unable to detect my headset/mic combo 3.5mm jack microphone.



The headphone audio is detected and working it’s just the mic. Also, I’ve checked that the microphone works with other devices.
I was running into this issue before I setup sys-audio, I was just hoping it would give me greater control in case I needed to install any missing firmware files.

Not even sure where to begin with debugging this as I’ve never dealt with this aspect of computing before.
