Hi sutapa, welcome to lq. First try running a mixer and unmuting sound, if that doesn't work, please post the output of the following commands from kosole.
/sbin/lspci -v
lsmod
Just copy and paste the results.
good luck.
<edit> I think those soundmax series cards are analog devices chipsets, if I'm right this should help.

Again, good luck. </edit>
