Nevermind, the microphone works, it was I that misunderstood how the testfirmware worked.

all good now!

Hi, Im also having issues with the microphone with my new esp32-s3-box3. :cry: I've ran the test firmware as described and my microphone seems to be faulty as well. The screen protector is removed as well. I've purchased the kit from the official espressif store on aliexpress. should I make a return...
