VB and Stereo Sound

Hi, I hope this is the right forum. I posted to the Games forum but didn't get a reply.

I'm writing a multitask app in VB6pro in which one of the taks is essentially like a hearing test where you would hear a tone in the left ear then the right ear, etc. I want to be able to send a beep (or other sound) to either the left or right speaker. I have no problem getting sound to play using the sndPlaySound function. I've also looked into using the WAVEMIX32.DLL. But I haven't been able to figure out how to control the left and right channels.

I assumed this would be easy seeing as how the speakers are in stereo but now I'm wondering if it's even possible to do this in VB.

Thanks in advance for your help.
