USB Microphone Android 9

Hi, I run Android 9 and tried to connect a mini mic via usb. At sound recorder it’s not detected. At Skype it’s not working properly - the sound recorded at sound test is too quite. Hardly not noticeable. How can it be fixed?
Thanks a lot in advance!

Whether the status bar displays the headset icon?

Hi, thanks for the reply! It’s not a head set. It’s a small usb mic. It’s working on my computer with iOS and notebook with windows 10 properly. but not on my rock 4 b with android 9.

No, I cannot find a bar to toggle e.g. the sensity of the mic.

How can the problem be fixed?
