Using Audacity 1.2.6 on Windows XP, the input selector is blank, and I can only record with the laptop's built-in microphone.
On two separate laptops, edit+preferences+audio i/o has two options in the recording+device selector: "Microsoft Sound Mapper - Input" and "SoundMAX HD Audio." Choosing either of these makes no difference; the input selector remains blank and only the microphone records.
On a desktop machine, there are the same audio i/o options in prefs ("SoundMAX HD Audio I" is selected; there is no "I" at the end of the laptop's selection), but the input selector has four options: Stereo Mix, Master Volume, Microphone, and Line In.
Like on the desktop machine, I would like to be able on my laptops to record sounds coming through the computer rather than from the microphone. How do I do this? I've searched this forum to no avail.
