Need help with recording system sound


I am using Windows 8.1 and Audacity 2.0.6

I would like to record the system sound. Like when I play a video or music I want to record what is playing through my speakers without having to use a microphone.

I tried how the wiki stated it but nothing was ever recorded.

I have attached the image of my available recording devices. Stereo Mix is active

For Audio Host drop down I have: MME, Windows DirectSound, Windows WASAPI

For Playback device I have: Microsoft Sound Mapper - Output, Speakers (USB Audio), Digital Output (S/PDIF) (IDT high definition), Speakers / Headphones (IDT High definition)

For Recording device I have: Microsoft Sound Mapper - Input, Stereo Mix (IDT High Definition), Line In (IDT High Definition)

I have tried every combination I could think of and still get no recording. Is this because my speakers were plugged in?

Any help would be greatly appreciated.

The current version of Audacity is 2.1.1 (available here:

If you select “WASAPI” as the “host” in the device toolbar, there will be a “loopback” option in the recording settings. See here for more details:

If you mean the USB speakers were plugged in, yes. You cannot record computer playback from USB speakers using stereo mix.

Use the WASAPI loopback per Steve’s suggestion.
