Recording - no devices found

I have just updated Audacity to version 2.0.0 and now find that I am unable to record streaming from my sound card (Realtek). When I go into Preferences in Audacity I get ‘No devices found’ under Recording. I am using Windows Vista and have the latest sound card driver installed. Any help would be much appreciated. I had no issues with the 1.3 Beta version

On the same computer with the same operating system and the same sound card?

Check that “Stereo Mix” is enabled on your computer (see here for details: )

Stereo mix wasn’t enabled - great thanks for your help
