My motherboard is Asus P8Z77-V Pro with built-in sound chip. I have been trying to figure out a way to record sound that's coming through the speaker. So far I have tried a couple of software, both are showing no audio device, hence unable to record sound. Using Audacity as an example, it shows speaker as playback device, but for recording device, it's blank with no choice available from the pull down menu. All I want to do is record whatever sound that's coming out of the speaker, so I really can't figure out how this is supposed to work. I am running Windows 8 Pro. Any suggestion?
