I’m using macbook pro OS version 12.6.3 sound section input and output devices not showing how resolve the issue
Problem could be hardware related bro. but to diagnose you need to backup all your data and perform macOS clean installation. We do have a video guide about it.
If you can create Bootable USB then do it yourself. otherwise you have to take it to apple service center or third party service center that is good with MacBooks to do it bro.
If you still experience audio hardware not detecting problem in macbook, then its recommended to visit service center as problem could be hardware related.
