Sound Mixer on Windows to mix sound over several output devices

Question

I am looking for software that primarily let me mix sound over all devices, sound-cards etc.

For example to have sound mixed over a blue-tooth headset and laptop speakers.

It should also be possible to see where which apps (Like SKype for example) want to send sound where.

(This seems to be a bit different from what one usually looks for in an audio mixer).

Anything within Audacity?

Answer 1

For Windows 7, Stereo Mix like this:

1. Open Sound panel
2. Select Speakers as the default playback device
3. Go to the "Recording" tab
4. Right click and enable "Show Disabled Devices"
5. A recording device called "Wave Out Mix", "Mono Mix" or "Stereo Mix" (this was my case) should appear
6. Right click on the new device and click "Enable"
7. Right click on the new device and click "Set as Default Device"
8. Double click on the new device to open the Properties window
9. Go to the "Listen" tab
10. Click on the "Listen to this device" checkbox
11. Select your HDMI device from the "Playback through this device" list

And you're done, the drawback is that you won't have a microphone selected as default recording device, but for what concerns me I couldn't care less.

If not, then probably VAC (payware) from comment.

It might depend on audiocards and drivers.

Answer 2

Yes, there is something within Audacity. It's a bit hard to find, but it's actually even documented properly.

Here's the crucial bit:

Select your speaker device and Audacity will record everything that you hear through your speakers.
