Hi.

Open up a terminal and type lspci. If your sound card is detected, it should appear in the list shown by lspci. Please, post the results of lspci here, it might help in figuring out what problem you have.

Besides that, I found a nice tutorial on how to configure the sound on your laptop. You can take a look at it here: http://www.linlap.com/wiki/Configuring+the+audio+for+Linux

I hope it will help you out. If not, keep us informed and we'll try to find a solution!:)

Hello again:) Found another one, but it's for Ubuntu 7.10. It might be useful. Here it is: http://www.linlap.com/wiki/Configuring+the+audio+and+updating+ALSA+for+Ubuntu+7.10

Hope it works!

It seems that the sound card is detected. it could be a problem related to ALSA. It is possible that the sound may be available to root only. To find out if it works only for root, open a terminal and type: "sudo totem" (or any other player you might use). If you play a song and it works, then you have sound only as root user. To make it work for normal users too, open a terminal and type: "sudo chmod 666 /dev/dsp".

if this doesn't fix your problem, run alsamixer through a terminal. Now turn off everything related to IEC, press the ESC key to save the configuration and then type in the terminal "sudo alsactl store".

I hope this info will be helpful.
