Behringer VMX1000 USB and Audacity

Hello

I have a problem last week a bought a new mixer and recorded a radioshow in audacity.
The first show was recorded fine but last night it went wrong the microfoon channels where not recorded.
So tonight i was trying somethings out so see what the problem good be, i used a presonus audiobox to records my voice but that also was not working.

Please help!

If you are recording with one microphone, ensure that you plug your mic into the left hand channel (“Channel 1”)
