Microphone stopped working on HTC Vive Pro. Is it fixable?

We have a number of Vive Pro units in our venue and the microphones have stopped working on a number of them. HTC returns are known to be notoriously poor and slow and I am wondering if it is relatively easy to replace or repair it. I have heard this is a common issue.
