Fraps spelar ej in ljud

Jag själv använder inte fraps så ofta men är du säker på att du har ''Record Sound'' ikryssat ?
Sen så hittade jag detta i fraps FAQen

''How can I adjust the volume of the sound that is recorded?

You must configure the volume through the "Sounds and Audio Devices" item in the Control Panel. Use the following steps:
# Click on the Control Panel and select Sounds And Audio.
# Click on the Audio tab.
# Find the Sound Recording device and click Volume.
# Adjust the volume for the Input that Fraps is recording from. This is usually named "What U Hear", "Record Master", or "Stereo Mixer".
If you can't see the correct Input on screen you may need to enable it by clicking on Properties in the menu and ensuring all Inputs have a check beside their name. ''

Vad jag vet så går det endast att får så att Fraps spelar in ljud direkt från programmet i Vista. I Xp måste du ha en mick?
