So I upgraded to firmware 1.6, but now I have another issue. The recordings are almost inaudible. Even if I speak loudly close to the audiomoth. It is not related to the upgrading to firmware 1.6 as this issue appeared 2 or 3 days ago before I upgrade the firmware.
What can be wrong ? I use the same settings as before (sample rate 48, gain Medium). Is my mic fried?
Are there any signs of weather damage on the device, such as water ingress or corrosion?
So, what I did, I put gain on the highest selection possible. But it looks like my mic lost sensitivity...
It sounds like this might be the microphone. Are you using any filters when you record?
