Those sneaky people at Microsoft have been trying to hide some of the sound recording functionality in Windows 7.

If you want to record the stereo mix from your sound card you might find that it has been disabled by default, to enable it do the following.

1. Right click on the speaker and click Recording Devices.
2. Right click within this window and select Show Disabled Devices.3. You should then be able to see a Stereo Mix icon, right click on this and select enable.
You should now be able to use your stereo mix as a recording source.
