Hi! There has been an Audiomoth 1.1.0 on my desk for some time. I have been trying to record with it, but it only records constant noise/hiss (at all frequencies) at maximum volume. I get the same result whether recording in default mode or in custum (also at lower gains). I use the recommended SD card (Sandisk extreme 64 GB) and recharchable batteries (both Varta 2600 mAh and Duracell 2500 mAh). Any idea how I might solve this? Thanks in advance!
