LinuxQuestions.org - sound card(yamaha OPL3 SAx ) not working in RED HAT 9

i am happy that my internet problem has been solved in this group and now i am surfing internet in linux.
but there is one more problem :
my sound card is not working (instead it is working in win2k)
I THINK that it is detected but there are no drivers/modules for it.
when i start GUI is says : couldn't open mixer device /dev/sound/mixer
and when i shut down, it failed to stop one service and displays error: can't locate module sound-service-0-0aumix: error opening mixer.
being a new member i dont know how to configure or load modules
i tried the follwing command:
[root@hotwire-196-148-16-del root]# cat /proc/pci
