I downloaded Veadotube Mini in Windows 11 and it doesn't recognize the camera nor the mic.
Reopened multiple times, ran as Adminsitrator and nothing.
VeadoTube only uses your mic for detecting loudness to change between "still" and "talking" images. There's no camera-related functionality. Does your mic work with other applications, like if you add it as-is to OBS does the sound level fluctuate? Maybe your mic is being used by another application that takes precedence?
