Stereo Mix-How To Record Microphone and Music

I have a Dell Inspiron 1545 and have been working on this stereo mix problem for a few hours today. Here's the solution I've found using Windows 7 and the IDT High Definition Audio.

This should work for any Window 7 system having the seeming lack of a stereo mix capability.

1. Go to the Sound controls for recording devices (right click on the speaker icon)

2. Right click on Rec. Playback and enable it.

3. Right click on your microphone and enable it and set a a default device (mine is a Logitec Pro 9000 webcam microphone, and I've set it as the "default communication device"

Here's the secret part:

4.When you click on your microphone then click on the "properties" button, and then click on the "listen" tab, and then click on "listen to this device"

Make sure you disable the Microphone/Line in by right clicking on it. As far as I can tell you can not have this enabled. It should read "Currently disabled" if you are doing this correctly.

Now you can hear your mic through your headphones and hear music playing through the Rec. Playback at the same time, and you should be able to then record or use it with any program to simultaneously play/record microphone and music.

I use it to broadcast my webcam with music and microphone at Don Browne - Florida on Justin.tv and it does work for that and should work for your use. (There is an slight echo heard through your earphones when you are using the mic but it does not show up on the recording)
