Introduction to Linux - A Hands on Guide
This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

Well, in alsa the numbering system is card 1 = hw0,0 card 2 = hw0,1 and so on. Usually you can send stuff to /dev/dsp but if that doesn't exist you will need to send stuff to /dev/snd/[name of device] or, more likely, /dev/sound/[name of device] usually named "audio" or "mixer" or similar, you just need to work out where to send the sound to! I wish I could help further, please look at the devices II mentioned and see if you can get any sound mixing frontends to use them (eg. alsamixer or gnome-volume-control or kmixer or whatever). Post back if you get stuck.
I had the same problem a few weeks ago, I did an upgrade from breezy. I pulled out all the stops, no sound so I re-installed breezy then 6.06 final came out I upgraded and the sound worked fine, go figure.
Unfortunately I'm not so lucky...my recommendation for people wanting to try out Dapper....wait until they fix the sound issues because I'm not the only one. Canonical better give this some attention or they'll start to lose some users to other distros.....and I myself will only wait so long with no music until I install FC5.
That's a shame, I heard they really did a good job of it. Do you have a development env.? You could try dl'ing the alsa driver, utils and libs, compile it and see if that fixes things?!
Remove the originals first, or better still, use checkinstall to make your own .debs
It is there however:
lspci | grep Motorola
0000:05:08.0 Multimedia controller: Motorola DSP56301 Digital Signal Processor (rev 02)
The strange thing is that I can't find the module snd-darla20 anywhere on my harddisk either. I'm running the K8 SMP kernel and the required kernel modules for any of the echo cards are not to be found in the /lib/modules dir.
Does anyone have an idea on how to fix this? The only thing I can come up with is recompiling alsa from source. reinstalling the packages doesn't work and I can remove it either since it then wants to remove ubuntu-minimal and -base as well.
Ok I got mine working. The first thing you need to do is install alsa by compiling source. You'll need to install the driver/firmware at minimum. What you may then find, as I did, is that it can't load the firmware file (you'll see an error on startup indicating that it can't find the file to load). All you need to do is move the .fw file to the correct location and all should be fine.
Thanks! I already did the same you suggest, following this guide:
<sorry for some stupid reason I'm not allowed to post a link. Go the the ubuntuforums dot org site, video&sound, "comprehensive sound problem solutions guide", thread 205449>
and choosing the second option "Using drivers from alsa-project".
In case anyone else runs into trouble, don't forget to install the alsa-firmware from the alsa-project website first!
Finally I had to do a reboot after the driver make/make install, both a modprobe and a depmod had the darla20 kernel object complaining about version mismatches.
