I have bought a FIFINE K669B USB microphone. Ubuntu 20.04 it is able to detect the USB microphone, however if I go to pavucontrol settings and select the microphone as input device, it doesn't detect any signal from it. In fact it does not show the bar where you can see if there is any input sound. I have also tried the microphone using another applications like Zoom or Discord, but even if you turn the volume of the microphone to the max the OS does not receive any signal. Additionally, the mic works when the system boots and then the mic is connected. However, it does not work when the mic is kept connected after reboot.
What would be the steps to make the USB microphone work on Ubuntu?
Cheers
