To paraphrase the old X-Files TV show: the answers are out there. You will have to dig a bit.

I tried another google search with the arguments "linux driver OPL3-SAx" That resulted in, among other things:

Linux soundcard stuff
Linux Sound HOW-TO
OSS Driver Download where I could specify the OPL3-SAx soundcard and Linux 2.4 (X86) os version

Think of it this way -- you're not likely to find anyone here who can give you a step-by-step procedure for installing sound on DSL on an 8-year old lappy. However, if you have done your resarch, gotten drivers, and are struggling with config, you'll get better help.

This article on Puppy Linux install on Libretto also discusses sound config. The answers really are out there...

Tried it again and again but still no success

Maybe a user with a L100 with sound could help me any further

I have a L100 running great with DSL, both sound & graphics work fine. At this precise time I don't have my libretto to hand so can't give details of the sound setup - it isn't as straightforward as the graphics. I'll post it here as soon as I have the time (hopefully in the next couple of days). You definitely DO NOT need to rush out & buy any drivers / software.

The graphics question is easily solved. See the WIKI (http://damnsmalllinux.org/wiki/index.php/Vga%3Dxxx) [I added the bit at the bottom of this page - hence the reference to the L100!]. To let you skip straight to step 6 of the instructions - for a L100 you need to use the cheat-code "dsl vga=808" at the boot prompt. The only other 'vital' piece of info you may want to know is that to move a window when the title bar is off the screen; position the mouse anywhere in the window then press the ALT key then left click & drag the cursor to move the window.

The L100 is great with DSL. I can listen to MP3's & browse using firefox with no interruption to the music - try that under Windows!! The battery life also seems vastly improved under DSL, I have had over 2 hours out of a battery that barely gives 45 min under W98 (even with the NOP patch for W98), also the PCMCIA cards run cooler (this may be due to the whole machine running more efficiently). Defininitely recommend DSL for the L100.

That would be great!
Up to now there are some applications I had to run under Windows because the sound card doesn´t work.
For all other things DSL is the much better choice.
I am using the extended battery and am getting 4-4.5 h runtime with my L100!

OK, to get the sound working put the following into /opt/bootlocal.sh:

modprobe ad1848 isapnp=0
modprobe opl3 io=0x388
modprobe opl3sa2 io=0x370 mss_io=0x530 mpu_io=0x330 irq=5 dma=1 dma2=0 ymode=2 isapnp=0 multiple=0

There may be a problem with accessing all of the volume controls if you are using an older version of DSL (about 2.2 or 2.3). John altered DMIX recently to cope with systems such as the L100 which use 2 separate mixer devices. In DMIX you should see a total of 13 channels which you can control. If you don't you won't be able to contol the master volume, bass, treble, momo mic (the built in one), or digital input (not sure what this is, but it's listed as a channel if you do 'umix -q' in a terminal window). I'm still running DSL2.4 so I can't comment on any problems with DSL beyond that release - just laziness that I haven't upgraded.

If you have any problems with the graphics or sound settings I've suggested let me know & I'll double check my system.

Andrew.

EDIT...... Just noticed you are running DSL2.1. If you don't want to upgrade I have a modified version of DMIX which will allow access to all the L100 sound channels. I've also sorted things so sound settings are reloaded after a reboot. John found a problem with my version of DMIX if too many volume adjustments were made in that it crashed with a segmentation fault. No obvoius reason why it should. I have repeated the fault, but only under severe use of the volume control. Under normal use it seems to be OK. Even when it does crash it restarts OK from the button in the dock.

EDIT #2......

Having checked my setup again you don't need the first line (modprobe ad1848 isapnp=0). I think I'd put that in while testing things & hadn't checked whether it was really necessary, it gets loaded with the opl3 module anyway.

Also DSL 2.4 has the version of DMIX which John updated to cope with systems such as the L100 with 2 mixer devices in use. If you update to at least 2.4 you should have no problems.
