Windows 7: Stereo Mix enabled but not working

I'm trying to get the Stereo Mix device under Recording Devices to actually broadcast sound, but I can't seem to figure out what's wrong with it.

It's enabled, and even set as a default device. I also can't seem to get programs like CamStudio to record the sound even though the option is enabled. Another example of my problem is even though I have a video open in ManyCam, it won't broadcast the video's sound, although I can still hear the sound from the program itself.

This computer originally came with Vista, and none of the above worked then, either.

Here's a picture of my recording devices: http://i38.tinypic.com/11s1r8y.png

I've tried updating the driver from this link: Realtek High Definition Audio Codec (Windows Vista / Windows 7) - Free software downloads and software reviews - CNET Download.com



But with no luck.

I just purchased HP Pavilion p6510f and it has this realtek codec as well. Enabled the stereo mix which was disabled as default and I am having the same problem. When I play a song or anything, no green bars going up and down on the stereo mix.

I updated my drivers already and read articles upon articles. There doesn't seem to be a solid answer yet. Anyone have a fix for this?

Nick,

Just to clarify... you have it enabled as the default "Communications Device".

It's not set as the defalt "Record" device.

That's why you're not getting anything.

I managed to figure out one way to get it to work, but it won't work if you have headphones plugged in.

Right-click the sound icon by the clock and go to Playback Devices. Right-click Speakers and go to Properties. Switch to the Levels tab, and unmute the Microphone.

Piece of cake. This is what I did. Simply go to the other devices present under the Recording tab, such as internal and external mics. Go to their properties and make sure that for each of them the "Listen to this device" option is UNchecked. Now, get back to the Recording tab. If you had previously set Stereo Mix as standard device, it will no longer be show as unavaiable. If you hadn't, do it now so it might work - I had, so it was working when I unchecked the device-listening box of external mic. Have fun.
