Internal microphone recognized, but no sound input
I have a 13” Mid-2012 MacBook Pro (MD101LL)
The internal microphone is shown in prefs but non-functional. Built-in internal speaker works fine, iSight camera video works fine.
Not sure if software or hardware issue - no issues found with Apple diagnostic test. Here are some screenshots:

Well as you didn't post any graphic of the input volume setting for the mike, I have to ask if the microphone input level is turned up high enough and/or if there is a mute function on that computer for the microphone? Wouldn't be the first time I've seen that kind of omission. :-)

No sound input even when input volume is maxed. Same with ambient noise reduction on or off. No mute option shown for the internal mic in system prefs or anywhere else I can see.

ZT, why do you think the mic input isn’t working? What are the observed symptoms? (May seem like a strange question, but could be important to troubleshooting.)
