where is my sound?

it was easy as pie to dual bootbut the sound is very important for me. also why is the mail they offer say that i have a broken pipe line?

Have you tried playing with the volume sliders in the Mixer applet? (the little speaker icon in the top bar, click it)

I meant, double click it. Then the big Mixer appears.

i have tried that and it doesn't work. this is new i have been using XP and Vista things are in different places but i'll do fine. but no sound still

Let’s check if your soundcard is recognized, ok? Would you please open a terminal window and type

asoundconf list

in there? Find Terminal in Applications → Accessories. Then paste the text here.

Then, which program are you using to test sound? Playing an MP3 or something?

it says Intel, my speakers from my computer
