Help identifying surface mount component

[tatersalad]

I'm working on a handheld ham radio, its lost all audio input. Emergency tone transmits but no audio. I've narrowed it down to be what I believe to be an mic amp but I'm struggling to find the part on the interwebz. I've attached a picture red is the amp and yellow is the mic line into the circuit. I'm completely green to component level stuff kinda self learning with trial and error. I've got a decent bench going just not sure where to probe without a data sheet.. im sure some of you can do this in your sleep so please excuse my water behind my ears im still a baby.

Could you let us know the make and model number of the radio?
That way someone may be able to look it up for you.

Baofeng rd5r its a dmr hand held. I did some probing around with the scope and got some mic signals that look amplified so I've kinda ruled that out, now I'm just trying to figure out how this circuit works so I know what direction to head from here. Another picture with more of the board for more viewing pleasure

The little black parts are most likely ferrite beads. You will have to measure with LCR meter.
