Can any one say whether 'Record what you hear' / stereo mix option is available in Asus xonar U7 USB sound card. I have this option in on board sound card.
If you mean record what is currently playing from your PC (while watching youtube, etc) then what you need is a software that can capture what is being played.. There are many tools that do that - search google for - Streaming audio recorder. I have also used Goldwave to capture what is being played. AFAIK, it should with any sound card.
