Respeaker USB with firmware 1 channel fails in windows

I just bought the respeaker USB and tried to use it.

In factory settings it works fine but as soon as I flash firmware 1_channel_firmware.bin

sound input is not recognized in windows.

the sound options shows no sound input and audacity also fails:

Hi,



What’s the error message saying, I can’t read the language.
