New to this

I’m sorry this has probably been answered a few times, but I’m new to this and not much of a computer guy. I want to download this motivational speech from YT to my phone so I can listen to it while I run and maybe some others. I have windows 7. I tried the FAQ area too and I think it dug me into a bigger hole. When I record it goes through my microphone so I disabled that and the other mic. But now when I go to record it says “Error while opening sound device. Please chekc the imput sound settings and the project sample rate.” Again I’m sorry cause this has been probably anwsered a lot, but I really need some help

See this for how to record computer playback Audacity Manual .

As described there, you can go to the “Recording” tab of “Sound” in the Windows Control Panel to show and enable disabled devices (which may or may not include a device to record computer playback).

While you are in “Sound” it would be a good idea to re-enable the mics.

You can easily download (as opposed to record) video files from YouTube (if that is what you mean by “YT”). Just do a search on Google.
