Flashed Audiomoth 1.2.0 to be USB mic but Live App doesn't recognize the input device

Hi Alex,

I have Flashed Audiomoth to perform as an USB mic. The app recognized the laptop internal mic as default and when I denied permission for being default input device in hope the app to recognize the Audiomoth as default input device it says "could not initialise input device". I've tried with the three settings (Custom, USB, Default), and nothing happens. Also tried with and without micro SD card and batteries. Am I doing something wrong? I suppossed that if using it as USB mic the micro SD and the batteries would not be necessary. Thank you.

Hello Again Peter!

After some months I'm experiencing a similar issue. With a flashed audiomoth to work as an usb microphone with the latest firmware version (1.2.1) the live app seems to be not recognizing the input device, the message says: could not initialise the input device. When in Custom mode red light flashes at high rate but with no response on the live app, likewise when in Default mode, but with the green light flashing at high rate. At USB/Off mode, the green light is solid. Also did what you recommended before of checking if the device is listed under audio devices, and it is listed as such in the device manager. Help me please. Thank you in advance.

If you switch the AudioMoth to CUSTOM or DEFAULT, can you see the AudioMoth listed in the Device Manager as an input device? Can you post a screenshot of what you see in the Device Manager? Which version of Windows are you using?

There is also an option on the 'Sound, video and game controllers' panel I think to 'Show hidden devices'. Windows caches all the devices it has seen in the past, and removing these cached devices may help.

Hi Carlos,

Did you manage to resolve this? You should just be able to flash the AudioMoth USB Microphone firmware, switch to CUSTOM (the red LED will flash rapidly) and then the microphone will appear as a regular USB microphone on your computer. It will appear in the standard audio settings (depending on your operating system). The AudioMoth Live App will find and connect to the microphone automatically if it is present, and use the default audio device if it isn't. It sounds like your computer can't see the AudioMoth USB Microphone as a regular USB device for some reason. Alex

Hi Carlos,

A couple of questions so we can help diagnose the problem. First, which operating system are you using?

If it's Windows, plug in the AudioMoth and set it to CUSTOM. Once that's done, open Device Manager and let me know if any AudioMoth USB Microphone devices are listed under "Sound, video and game controllers"?

Thanks,

Peter
