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've problems with my sound card (an hercules muse XL)
When loading the desktop, it get this error message
Sound server informational message:
Error while initializing the sound driver:
device: default can't be opened for playback (No such file or directory)
The sound server will continue, using the null output device.
If i launch xmms, i get this error (even if i'm root)
** WARNING **: alsa_setup_mixer(): Failed to find mixer element: PCM
ALSA lib pcm_hw.c:1055snd_pcm_hw_open) open /dev/snd/pcmC0D0p failed: No such file or directory
** WARNING **: alsa_setup(): Failed to open pcm device (default): No such file or directory
it seems your sound blaster device (/dev/snd/pcmC0D0p) doesn't exists in your /dev/dir, maybe the MAKEDEV script solves this, but I'm not sure about the effects it has on the /dev structure... maybe some other member here or some man page can tell you more about this...

:edit: maybe the alsa setup can help you with this too, but don't know where it is, don't use alsa
I too am having similar problems.
I have slackware with a voyetra montego II sound card.
I am able to play files from a CD but am unable to play mp3 files using for example real player, or xmms or alsaplayer.
I get the following message with xmms :
** WARNING **: alsa_mixer_setup(): Failed to find mixer element: PCM
ALSA lib pcm_hw.c:1055: (snd_pcm_hw_open) open /dev/snd/pcmC0D0p failed: No such device
** WARNING **: alsa_setup(): Failed to open pcm device (default): No such device
I am logged in a root when I get the messages with ALSA. The device exists alright.
ls -al /dev/snd/pcmC0D0p
crw-rw--w- 1 root sys 116, 16 Aug 29 2003 /dev/snd/pcmC0D0p
I have seen some messages mentioning that all the sound devices should belong to a group "audio" and you should NOT be logged in as root but as a normal user that belongs to the audio group.
I do not understand how this could make a difference.
