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.

When I boot into 2.4.22, my sound mixers work fine, but when I boot into 2.6.0-test7, they don't work. What's up with that? When I boot up and load KDE, it says that it can't find the mixer. When I type in any command for alsamixer it says:
alsamixer: function snd_ctl_open failed for default: No such device
Hence the 2.6 kernel. They call it testing for a reason, expect things to break. Fixing them is for the guru types, although it is possible I sit comfortably with 2.4.22, I ran 2.6 for a while but didnt expect much.
Actually, I booted it back up into 2.4.22, and it did the same error, so I'm guessing(logically) that when I installed my 2.6 kernel, that it erased my mixer programs. I ended up checking out what the message is right before X11 loads, and the shell said:
ALSA warning: No mixer settings found in /etc/asound.state
FATAL: Module snd_pcm_oss not found.
FATAL: Module snd_mixer_oss not found.
I'm thinking I'll try to recompile my kernel to include OSS(Depreciated) or just get rid of OSS emulation for ALSA, which do you think is the smartest move?
Did you check the /lib/modules/modprobe.conf to see if you config for you sound card was included?
Mine is the following:
alias char-major-116 snd
alias snd-card-0 snd-intel8x0
alias char-major-14 soundcore
alias sound-slot-0 snd-card-0
alias sound-service-0-0 snd-mixer-oss
alias sound-service-0-1 snd-seq-oss
alias sound-service-0-3 snd-pcm-oss
alias sound-service-0-8 snd-seq-oss
alias sound-service-0-12 snd-pcm-oss
options snd major=116 cards_limit=1 device_gid=29 device_mode=0660
options snd-intel8x0 index=0
Also use a different volume control program if possible. I use gnome 2.4 volume control in KDE 3.1.92 (3.2). Also it shouldn't be an issue with booting but maybe chmod 0666 /dev/mix* /dev/dsp*
I actually don't have a file /lib/modules/modprobe.conf I have two directories, one for each of my kernels, and within those directories, I don't have any files named modprobe.conf. I'm starting to think that maybe I should just download ALSA seperately and install that.... I looked for my soundcard in the kernel menuconfig, but I couldn't find anything that mentioned CMI 8738 MX DSP or anything of the like at all. Wish me luck! Once I get this ironed out, I'll work on my TI USB Calculator link again....

I have the exact same problem. schaez, I don't think the above document is valid if you are using the 2.6.0-test kernels. I have sound, but alsa mixer doesn't seem to work. But strangly, all other mixers do.
That's probebly cos i'm using oss emulation. No one at the alsa maling list could help me out. So i'l be watching this thread.
I ended up changing ALSA from Y to M in the menuconfig, and now I don't get an error before X11 loads up, but I still get an error saying that there's no /dev/dsp.... I'm going to go ahead and try to install ALSA separately, hopefully I'll get it.
Well, I got too fed up, so last night I wiped off my computer except for my /home partition. I'm going to try to start 2.6.0test7 again, but use modules for my sound instead of having it built into my kernel. Maybe I'll even get APM working too, now that I figured out how to get my computer to fully power-down!
