I am trying to configure what windows calls a Yamaha OPL3SAx sound system on Slackware 9. I have also tried to configure the system under slackware 8, but with not success either. The system is a toshiba satellite 2535cds. I have looked high and low at places like www.linux-laptops.net and other boards, but with not luck as to a solution. I have very little experience with kernel configuration, and anything I did know, I don't think applies that well to slack9.

The kernel is 2.4.20 and documentation says that the system should be compatable with the OPL3SA2 which appears to be the same configuration as the OPL3SA3 and OPL3SAx. However I have no idea how to configure the kernel or even what filet to start with since slack 9 seems to do kernel mods differently.

I also found some info that said that a standard sound blaster pro config should work, but I had no luck with that. I got many IO ranges from windows and windows doesn't say which range goes to what part of the card (IO, MPU, etc.)

In addition I have tried to use alsa drivers with also say they should work, but I am unable to configure the device irq and io parameters for the device so there is no /lib/modules/2.4.20/kernel/sound/isa/snd-opl3sa2.o file in existance.

The solution is probably simple but I don't know where to go from here. Can someone please help me?

Thank you, Gabe_228

got not copy of Slack 9 here. try checking /etc/rc.modules

also, try here:
http://www.alsa-project.org/alsa-doc/

Try putting this in /etc/modules.conf. I had the same problem, and this fixed it right up:


alias sound-slot-0 ad1848
options sound-dmabuf=1
alias synth0 opl3sa2
options opl3sa2 io=0x388
options ad1848 io=530 irq=5 dma=0 dma2=0

That should do. If not, try other opl3* modules. Also, check your values from your system, my laptop is a Sat Pro 470, but same card. Yours may be different.
