Yamaha OPL3sa2 sound card with Redhat9 linux 9
 

I Installed RH9 on my Acer Extensa 500DX Laptop. A lot seems to be working but I have a problem with sound. my sound card is Yamaha OPL3sa2, after compiling and recompiling my kernel i fanally got it working with the original kernel but it worked only once.I run the following modeprobe command:

[root@localhost root]# modprobe opl3sa2 mss_io=0x530 irq=5 dma2=0 mpu_io=0x330 io=0x388

and get this:

/lib/modules/2.4.20-8/kernel/drivers/sound/opl3sa2.o: init_module: Invalid argument
Hint: insmod errors can be caused by incorrect module parameters, including invalid IO or IRQ parameters.
You may find more information in syslog or the output from dmesg
/lib/modules/2.4.20-8/kernel/drivers/sound/opl3sa2.o: insmod /lib/modules/2.4.20-8/kernel/drivers/sound/opl3sa2.o failed
/lib/modules/2.4.20-8/kernel/drivers/sound/opl3sa2.o: insmod opl3sa2 failed

when i check my messeges log this what it says:

looks like something is working or is it? and Ideas

maybe...
 

Try "irq=auto" instead. Just a thought. Good luck.

oh yeah-this too
 

Also if you insmod the module, the module is only inserted temporarily. When you reboot it goes away. That would explain it working only once. The way I understand it is that you have to add the insmod command line to one of your start up scripts to make it fire up at boot time.

I fanally got it working. the resources are assigned automatically in the cmos, a simple modprobe command did it all:

Modprobe opl3sa2

thanks anyway
