AudioMoth microphone issue
Dear Open Acoustic Devices team,
I’m writing from Spain regarding an issue with my AudioMoth v1.2 unit, which I purchased about 8 months ago through GroupGets.
Since about a month ago, the device has stopped recording properly. It still creates WAV files of normal size and I can hear the typical background noise, but no real audio is captured — just constant white noise.
Here’s what I’ve already tried:
Updated the firmware to version 1.11.0 (latest release).
Tested with several SD cards (properly formatted) and new batteries.
Checked different gain levels and sample rates (e.g. 32 kHz, Medium/High gain).
Verified correct operation in the Configuration App.
The problem persists in all recordings.
Given these tests, I suspect that the MEMS microphone may be damaged or disconnected.
Could you please advise me on how to proceed?Ideally, I would appreciate either:
Repair or replacement support (if possible under warranty), or
Guidance on purchasing the correct replacement microphone and instructions or tools to replace it myself.
Thank you very much for your help and for developing such a great device.Please let me know what information or photos you might need to evaluate the issue.
Best regards, David.
Thanks for the thorough troubleshooting list. From these points I'd also suspect a damaged microphone, which can occur when exposed to water. Is there any signs on the board of water damage or corrosion. It would be worth getting in contact with GroupGets to see if they can help before considering any DIY repair.
