Hi, I am trying to set up a recording with Xenyx Q802USB through USB.
I have plugged the microphone to the first XLR input, adjusted the volume and I can hear myself through "main out", but I can not capture any sound using Audacity. You can see my audio settings here: http://i.imgur.com/lOIQlDW.png
Please make sure you do not have anything connected to the 2-TRACK RCA in/out as the USB and the 2-TRACK function on an either/or basis.
Ensure you have selected the Behringer mixer as your default recording/playback device in your operating system. In OS X under Apple>System Preferences>Sound and in Windows under START>Control Panel>Sound/s and Audio Devices.
Does the mixer play back audio from your computer without a problem?
