Hello to everyone,

I'm trying to listen some music on my Beagle Board XM running on Ubuntu 11.04. I've attached the speakers cable on the input and on the output port of the beagle a lot of times,but I'm still hearing no sounds.

root@omap:/home/ubuntu# uname -a
Linux omap 3.0.4-x3 #1 SMP Wed Aug 31 05:51:34 UTC 2011 armv7l armv7l armv7l GNU/Linux

I tried launching the gnome-volume-control app and it just comes up saying "Waiting for sound system to respond..." and sits there indefinitely. Here's an example of what happens in mplayer when I try to play an MP3

root@omap:/home/ubuntu# mplayer dad.mp3
MPlayer 1.0rc4-4.5.2 (C) 2000-2010 MPlayer Team
mplayer: could not connect to socket
mplayer: No such file or directory
