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.

I'm using Ubuntu (Dapper) with KDE, on a Compaq Presario x1010CA, not sure of sound card model. Sound had been working fine for a couple weeks but spontaneously stopped working the other day. Nothing seems to be muted (including in alsamixer), I've restarted alsa-utils with no success, and restarting the whole computer didn't help either. Running "cat /dev/urandom > /dev/dsp" gives nothing but silence. This affects all sound types as far as I can tell. There are no error messages, just no sound.
I was under the impression that ubuntu is a type of debian distro. If I'm wrong, chalk it up to being a newbie. Regardless, since from your comment I guess it might have been misleading, I changed the subject on the first post, but I think it's too late to change the thread name.
The reason there are so many Debian derivatives: ... so Debian users don't have to answer this kind of questions.
Get off your high horse, rickh. I'm posting in the newbie forum specifically because I knew I'd have a lot of newbie type questions. If you don't want to deal with these kinds of questions then don't read them.
alsa-base (1.0.10-4ubuntu4) and alsa-utils (1.0.10-1ubuntu14) are already installed, but there is no alsaconf to run. I considered uninstalling and reinstalling them, but to do that apt-get wants to uninstall ubuntu-minimum, which sounds like something I can't do without.
Looks like nobody else is coming, so you're stuck with me. You'll have to live with my "high horse." Debian users are determined to help, but we have our own way of discouraging newbies from using Debian. Since you claimed to be a Debian user in the thread title, I naturally looked in.
There is obviously something unusual in your set-up since you say alsa-utils is installed but not alsaconf. alsaconf is part of alsa-utils. I think you are probably going to be forced to reinstall it. But I'm not really familiar with Ubuntu. It's rumored that they're very patient and friendly with newbies over at the Ubuntu forums. A google search turned up this page, http://www.ubuntuforums.org/forumdisplay.php?f=138
alsaconf must be run as root user.. on my debian system it is located in /usr/sbin
itg-debian:~# which alsaconf
ricks point about stating Ubuntu when you are running Ubuntu is valid. If it were Debian it wouldn't be a separate distro. Every distro does things a bit differently so stating the proper distro would get help more attuned to the way your distro does things. you should update your profile with your distro name and version ..
any luck with
sudo su -
if it locates alsaconf then try and run it...
That is the tool used to configure asla, if it's not on your system then something is broken and you may want to look at purging the alsa packages and re-installing them.
Yes, I realise my mistake now with the Debian/Ubuntu terminology. Like I said I thought Ubuntu was a type of Debian and the technical stuff would be mostly the same, but I stand corrected.
Anyway, there is no alsaconf, although sound had been working fine without it for weeks so whatever configuring that had to be done was done somehow. I wasn't doing anything as root when the sound cut out, so I don't think I could have changed the configuration...
I do have alsactl but can't figure out if it might be useful or not.
Ubuntu removed it stating that it is not necessary. Since Ubuntu doesn't use the same tools as we do to quickly configure Sound I would suggest you start with the Comprehensive Sound Problem Solutions Guide in the Ubuntu Forums...
Unfortunately the Ubuntu Comprehensive Sound Problem Solutions Guide isn't quite as comprehensive as it needs to be, i.e., it didn't fix my problem. Thanks though. It's good to know at least that I'm not crazy for missing alsaconf...
