Sound driver problem


Hello,
I've installed Ubuntu 7.04 in my pc.
Configuration:
CPU: 2.8 Ghz Pentium D
MB: Intel 945 GCL
Sound: Sigmatel (Onboard)

Ubuntu can detect my sound card, but cant produce any sound. Is there any special procedure I need to follow? Sound card is working fine on Windows Xp.

Any help is appreciated.

This is the obvious question, and I'm sorry to ask it, but this is the first step:

Did you turn the volume up? Just one volume up, or all channels? Sometimes the "master" channel in the GUI doesn't control the actual master volume. Also, there can be multiple volumes controlling the same channel (master+pcm, etc). Make sure they are all turned up. Again, I don't mean to call you an idiot or anything; you would be surprised how many people forget to check this.

Also, type "lspci" in a root console and give us the output, thanks!

I tried to set volume by clicking the icon on the system tray. Both channels are in maximum volume.

The "lspci" command shows the following output:

I have heard this is recognized in kernels around 2.6.19, but will not play sound. The fix, IIRC, is to get a newer kernel version. Type "uname -a" and post the output please.
Thanks!

This may get you started;
http://www.linuxquestions.org/questi...d.php?t=509778
also look at the part Manually Specify Module Parameters here
https://help.ubuntu.com/community/HdaIntelSoundHowto
I know its for ubuntu but it will give you the idea about
options snd-hda-intel model=3stack
it depends on your card, also some people get it to work by removing it; and others never get it to work.
I used the driver from realtek once and it worked;

I used the other
