Problems with OPTi audio 16

I have problems with my sound card OPTi audio 16.
When I start a computer it give me a failed and don't start sound
I need to run sndconfig to activate soundcard
I have Red Hat 8.0 and kernel 2.4.20
Soundcard detected don't detect soundcard

My /etc/modules.conf after run sndconfig is:

alias sound-slot-0 mad16
post-install sound-slot-0 /bin/aumix-minimal -f /etc/.aumixrc -L 
 >/dev/null 2>&1 || :
pre-remove sound-slot-0 /bin/aumix-minimal -f /etc/.aumixrc -S 
 >/dev/null 2>&1 || :
options sound dmabuf=1
alias synth0 opl3
options opl3 io=0x388
options sb support=1
options mad16 io=0x530 irq=5 dma=0 dma16=0 mpu_io=0x300 mpu_irq=9 joystick=1

In /var/log/messages appears this:
