no sound - unbuntu 7.10 on Dell Vistro
I am new to linux and just bought a Dell Vistro 1400 laptop. I have installed unbuntu 7.10 partitioned with Window XP home edition. The sound works fine when switch to the Windows, but no sound at all with unbuntu. I have checked the Sound Volume control (upper right on tool bar) and the sound preference, but cannot make any sound even though the volume is not muted. I also tried command : “cat /dev/urandom > /dev/audio” and it gives no sound either.
Could this has to do with the sound card compatibility? Would really appreciate if I can get some help.
Below are the results from command "lspci" and "lsmod"
