I have an Audiomoth device that had a problem the last time I tried to use it. I brought media attached to this message to better explain the error. The appliance is new, has been used 2 or 3 times and has worked fine before. LED lights behave properly, flashing red during recording, flashing green on sleep cycle. Voltage is 4.8. Sandisk Ultra 16GB USH-I class 10 card that works well on another recording device (Tascam DRMKII). Tests were done changing the card to Kingston HC-I v10, the batteries to new ones, resetting to DEFAULT and CUSTOM modes, and downgrading the flash to a previous version 1.5.0, and also making short recordings. But none of this had any different effect. Note that I used a setting of 600s of recording and 60 seconds of pause. Even trying other schedules, with shorter recordings, the error persisted. And I even tried to program it on a different OS, Windows and Linux.
Really, I'm lost in what could have gone wrong.
Any suggestions on what's wrong with it and what else I can try to make it work?

Hi Mariana, It looks like this is a hardware issue reading the data from the external memory on the PCB. That's why the interference is so regular - it occurs every 1024 samples. Is there any obvious sign of water damage on the board. Andy will be able to follow-up email@example.com. Alex
Hi Alex, thanks for your attention and quick response. Raw files also have this error (attached below). If this is a solution, is there any way to reset the device?
Hi Mariana, That's very strange. It looks like the file that you uploaded has been resaved by another audio application as the header comments and data are swapped around inside and it seems to be 24-bit audio. Do have the raw file that was on the SD card? Alex
