currently no audio output - troubleshooting audio

[Noah]

Hi there,

I have an ASUS Motherboard with built in audio and I am trying to get it 
to work with by ubuntu.  the same machine with XP the audio works fine 
so that takes the motherboard and speakers out of the question.

I am not able to get the ubuntu system sounds to play.  I am not able to 
get vlc, rhythmbox, and amarok to work and play audio out the speakers 
output jack.  The same external jack that XP can play audio out just fine.

so what are the steps to troubleshooting audio to get it to work with 
ubuntu?

Cheers,

Noah
