I bought a t.bone SC 420 USB Microphone.

Recording via Audacity works fine.

But as soon as the USB cable is connected to my PC, there is no more audio output.

I changed the settings, but nevertheless. The PC audio output is selected, but no sound is audible.

As soon as I unplug the USB cable of the microphone, audio output is audible again.
