OS X Sound Not Working

 

If your sound on your Mac has stopped working due to a hardware problem, this USB stick works on a Mac, at least under OS X 10.9

I tested it after taking it off my son's PC. Only note is that the volume is very sensitive but this could be fixed in a later OS update perhaps. I used the volume slider to control it vs. the volume keys but you could also be fine if your speakers have a volume knob.
