#14 Sound not working (e.g., headphones, speakers, external USB adapter)

I can't hear any sound from the headphones, the speakers, or a USB audio adapter that uses only free software. I installed the Xfce environment, and the pulseaudio package, but still don't get any sound.

Hey,

If you run the commands below, you'll have sound (worked for me).
