Why won't my sound work?

So for some reason I can't get the sound to work (I can't play MP3s and what not) when I'm using Knoppix. I have a Gateway computer w/ a Boston speaker system (they are the speakers that came with the system when I bought it). While booting it says that it finds my audio hardware.

Running lspci -v I get:

So can anyone tell me how to get my sound working correctly?

As secondary questions I have a Speedstream USB DSL modem. I know the problems with USB DSL modems, but if anyone has actually gotten a Speedstream modem to work for them then I'd appreciate knowing how they did it. Thanks!!!

I think that sound chip uses the i810_audio module, lets start by checking if it is loaded:
Run "lsmod" and tell us what you get.

windos_no_thanks (or anybody else) please be my teacher. I ran the command lsmod. What exactly does this command do?

The output was:

What does this tell us? Thanks!!

lsmod "just" lists loaded modules. (It does a little more than that, but that'll do for now). man lsmod will tell you a little more.

OK, from your lsmod we can see that your sound is OK. What you need to do now is to run alsamixer (probably from the command line) and whack the volumes up. Then find kmix (Kmenu>multimedia>sound) and turn the relevant channels up. That should do it.

BTW, what happens if you click on an mp3?

Okay, so I couldn't find alsamixer and couldn't run it through the command line. But everything else in Multimedia >> Sound I opened and turned up all the volumes. Still no sound.
When I click on the MP3 it opens it using XMMS.

So why does my sound still not work? Any more suggestions?

If you have installed to the HD then open a console window and use su to become root and then /etc/init.d/alsa-autoconfig then edit the file /etc/init.d/bootmisc.sh and add aumix -v 75 -w 75 to the bottom of the file to have the default volume set on boot. If you are running from the CD use the cheat code knoppix alsa when you boot.

Stephen probably knows what he is doing here but can anyone explain
why the sound module is loaded yet it has zero users:

Another thing that hit me: I don't know what a "Boston speaker system" is. If it is something that connects to the analog output things should be ok but if it uses the usb port we might be barking up the wrong tree at the moment...

I'm going with the theory if the devices themselves have not been created yet then there is nothing for the module to use (this happens when you install to HD and do not run the autoconfig) and the mp3 is playing but no sound another symptom now if the mp3 froze xmms then I would be thinking the artsd daemon getting in the way like it always does and while I thinking some more when he gets it going check the output plugin being used for xmms if it not set to the alsa output then may not get sound either. But the clincher is this you should have similar output to this if you are using alsa which some of them chips need:

Ok, thanks :-) However, I don't think this is a HD install since the cloop module was in use.

If it's not a HD install, then

knoppix alsa

as a cheatcode should do it. If not, then...................... ?
