A while back I posted a question about capturing sound with Audacity: https://forum.audacityteam.org/t/record-from-audio-stream/34042/1 That was for Windows 7. Now I’m trying to do the same thing with Mac OS X 10.5.8. I downloaded Audacity 2.0.5, and all that seems to be available for the inputs are: Built-in Microphone and Built-in Input. The Microphone option seems to work fine, but the Built-in Input option does not. If I play a video on youtube and hit record, no sound is recorded.
What must I do to be able to record sound playing on my Mac?
