Should I provide more details?
Can you help me solve this problem?
Thanks

From what I can tell, the module snd_hda_intel should support your sound. See this link

-->http://www.alsa-project.org/main/ind...dule-hda-intel

First, determine if and sound modules are loaded. In terminal, run the command 'sudo lsmod | grep snd_hda_intel'. If its loaded, several lines will show up as output. If it is not loaded, nothing shows up.

You can try and load the modules as described on the link, that may get your sound going. 10.04 is a bit dated, I did see some other threads with similar problems, and going to a newer release was required. I would expect you have the modules, so you should not need to try and build them. You should try and modprobe them. You will need to put sudo ahead of modprobe.

Now insert the modules into the kernel:

modprobe snd-hda-intel ; modprobe snd-pcm-oss ; modprobe snd-mixer-oss ; modprobe snd-seq-oss

The above is from the alsa instructions. You can load one at a time, or the lot at once.

Let us know...
