Thank you for replying so quickly - I haven't disassembled the device only removed the screen protector.

If there is a simple fix to try I'm happy to give it a go!

I'll reach out by email as you requested though.

Thanks again

Regards,
Hugh

Hi, Thank you for posting the information about checking the microphone. I ran the test diagnostic and unfortunately my Box-3 microphones appear to be faulty. I made sure to remove the screen protector. I purchased my Kit from Mouser - should I return it to them or direct to Espressif ? Thanks in ad...
