Reflashed the phone with no change, so it’s definitely hardware.

Has Purism support followed up with your issue since you created this topic?
No. I’ve only gotten the original response email, that gives me my issue number and says I’m in the queue.

I tried reflashing phone. No change in microphones, which I was pretty sure would be the case.
Neither top or bottom mic is working, but headphone mic seems to work fine. I’m looking at the MEMS microphone ICs for top and bottom. I might have to take phone apart and troubleshoot some more. I’m sure I have no warranty, so why not?
Anyone know what U510 on the Librem 5 mainboard is? It would represent a single point of failure for both MEMS microphone ICs, as it appears to transfer the clock signal to both. I don’t see a part number.
