Yes. That's almost certainly where it's falling apart.Could there be something wrong with my settings in my Windows 7...?
Right-click the speaker icon on the lower-right corner of your desktop (Leave Audacity closed). One of the options that opens should be the Windows sound control services. Volume Mixer?? Something like that. There should be volume controls, bouncing light sound meters and muting controls??
This is where the Windows elves take over. I can't give good detail on this.
Even if you get everything else working, Windows may try to apply voice processing to your music. You may get music that bubbles, garbles and fades by itself. That's another set of Windows controls.

This seems to be a lot of work for a simple job, but it's not the job Windows machines are designed to do out of the box now. They're business machines and they come all set up for conferencing, chat and business meetings. Not songs.
