WASAPI is usually only required when you want to record audio that is
playing on your computer. In this case you must select the "loopback"
option for the recording device, and the same device for the playback
device. For example, if you have a "Realtek high definition audio"
sound chip on your motherboard, you will have options something like:
Recording device: "Speakers (Realtek high definition audio)(loopback)"
Playback device: "Speakers (Realtek high definition audio)"
The "loopback" option generally works for all Windows (Vista or
later) computers. When recording with WASAPI loopback, you may need to
start playback of the thing that you want to record before you start
Audacity recording (so that there is something for Audacity to
Recent versions of Audacity may also provide additional WASAPI
recording options, but they will only work if your soundcard fully
supports WASAPI. Unfortunately some soundcard drivers are rather
flakey with WASAPI when not using "loopback", in which case you should
use Direct Sound or MME as the host.
