I have a Circa 1998 Compaq Armada 1750. Reading my notes and googling, I found some information.
In my BIOS, I needed to nake sure the sound is activated, which it was, and also alter some IO, DMA configurations. Also, I need support from the kernal sound-support, namely sound.o, soundcore.s and the Soundblaster-module, sb.o.
Here are the requirements for the IO, DMA:
I/O-Port=0x220
IRQ=5
DMA=0
MPU-I/O=0x330
In using Debian it was stated that the /etc/modules.conf contain the following:
alias sound-slot-0 sb
options sound dmabuf=1
alias synth0 opl3 io=0x388
options sb io=0x220 irq=5 dma=0 mpu_io=0x330
It's been a while since I had a Linux distro installed, but I recall that a Slackware and Arch and PCLinuxOS all had sound working.
I have compiled the kernel for another computer for a learning experience and to fix another problem. I don't know if that's what's needed and even advised here. Maybe just adding the modules listed would work.
Thanks for your help.
PS- Last night I finally got DSL imbedded to run and tried the XMMS that is part of DSL. It too complained of not seeing my sound card. Interesting is that on reboot the is several lines of text trying to modprobe the sound card but couldn't find the module.
