Luke, thanks for your help. I've already turned up the volume level and it didn't work. I also selected the "earphone connector", as you suggested, but it didn't work either. Besides, when I selected "earphone connector", it comes no sound from the speakers, so I changed back to "analog output".
Finally, I updated the audio drivers and it didn't work as well. My motherboard is a Biostar G41D3C. The one I was using before was a MSI (don't remember the model), and the sound was perfect, both on Ubuntu and on Windows XP. I have also looked for a proprietary drive on Biostar's website , but it does not support Linux, so I'm thinking of going back to MSI.
