When I play a .wav file with paplay, no sounds happen. If I try 'cat /dev/urandom | pacat' no sound happens. I'm using the sound jacks on the systemboard (I have no separate sound card). I know they work because when I boot into Windows, it plays sound okay. I know pulseaudio is running because I see the process when I run 'ps aux | grep pulseaudio'.</div><div style="color: rgb(0, 0, 0); font-size: 16px; font-family: HelveticaNeue,Helvetica Neue,Helvetica,Arial,Lucida Grande,sans-serif; background-color:
