BeatDetector - Value and sound card

hi all,
I am a new user of VVVV. I have a question: can I use the BeatDetector node with an integrated sound card or I need a dedicated one.
When i select the BeatDetector and press F1 AudioIn node in ok, but the AudioRecordSelector is red…

you don’t need AudioRecordSelector on win7 anymore, thats a XP thing. in win7 you can select the input device at the driver enumeration of the AudioIn node.

thx tonfilm!
