Multimedia :: Help setting up sound on my 550CDT



Hello I'm not very good at running Linux systems yet but have a nice working install of DSL running on my laptop, apart from I am unable to setup the sound.  I am very confused over the steps I need to take.  As I understand it there are two sound systems OSS and AlSA but I only need to setup OSS if all I want is midi wave and mp3 playback?

I duel boot with Free Dos so I know my laptops sound works here are the settings in the BIOS:
WSS I/O Address = 530H
SBPro I/O Address = 220H
Synthesizer I/O Address = 388H
WSS & SbPro & MPU401 IRQ Level = IRQ5
WSS(Play) DMA = Channel 1
WSS(Rec.) & SBPro DMA = Channel 0
Control I/O Address = 370H
MPU401 (MIDI I/F_ = 330H

The sound chip is a: Yamaha OPL3-SA3
The laptop is a Toshiba Tecra 550CDT

Any help at all would be greatly appreciated as I am totally stuck :(
first boot with "dsl nosound". I had an opl3-sax chip myself, and the knoppix hw recognition program recognized it as something else, thus no sound. After a no sound check boot type "sudo modprobe opl3-sa2" and check if you have sound after that (play something in xmms etc..)

If you don't get automatic sound, type "modinfo opl3-sa2" and it will show all the params that can be given to the driver (irq, i/o etc..)..
Both the modinfo and the modprobe return that there is no module by that name found.

???
oh sorry, typo, no dash between, it's opl3sa2
aha just figured it out when I refreshed :D
unfortunately no sound still tried selecting OSS and ALSA iun xmms and it still errors.
The mixer app also crashes if I try and change the volume.

Modinfo gives the foloiwng:
uses AD1848 MSS driver
parm: io int, description "sets I/O base of card (usualy 0x370, address must be even and be from 0x100 to 0xFFE)"
parm: mss_io int, "set midi I/O base (0x530, 0xE80, or other address must be even and from 0x
parm: irq int
parm: dma int, "set mss audio first DMA channel 0,1,3"
parm: dma2 int, "set mss audio second DMA channel 0,1,3"
parm: ymode int, "some 3d thing 0=desk 1=notebook 2= notebook 3=hi-fi"
parm: loopback int, "set A/D input source 0 mic rch 1=mono out"
parm: isapnp int,  "when set to 0 isapnp disable_
parm: multiple int, "when set to 0 will not search for more than one card"

how do I use these (I missed some info off as I cant see how to copy test from bash)
