Enabling Stereo Mix

It is recommended that VidBlasterX should be used with an external audio mixer, which would take both audio from modules like Player and audio from the PC and external sources like microphones, in order to obtain full control of levels and monitoring (as described in Audio Overview). However, for some simple applications it is possible to route audio through the PC in Windows 7 using the Stereo Mix software device. This is a re-named version of the Windows XP "What-you-hear" function, but it usually remains hidden in Windows 7. Here's how to enable it.
