Record Audio?

I want to record audio from one of my workout videos to take with me on a trip. In the past, I had done this with audacity. However, when I open audacity now on Win 8, it says there is no sound device. Does anyone know of a way to just record the sound output from my machine? I.e. I would play the entire video, and just record the sound and take that with me.

You need to have the "System Mixer" (may be called "Stereo Mix") selected as the default Recording Device.

I'm not using my Win 8 system right now so I can't tell you exactly how to access the Sound Panel, but in the Recording Tab section if the System Mixer/Stereo Mix is show, enable it and set it as the default recording device. Audacity should be able to use this.

If its not shown, RIGHT click in an blank area in the panel and then click to show both Disconnected and Disabled Devices. If the System Mixer/Stereo Mix is now shown, you can set it as the default recording device.

This assumes you have the correct sound driver installed from either the PC vendor or motherboard vendor, as applicable. If you only have the generic basic function Windows installed HD Audio Codec that will not get you what you want. (Also please fill in the My System Specs - it helps us to try and help you).
