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.

Does anybody out there have experience with USB audio devices under Linux?
Here's the reason I ask:
Back when I ran my computer under Windows 98SE, I used a Creative SoundBlaster MP3+ USB audio device for my music playback. When I switched to Linux, (currently Mandriva PowerPack 2006) I just assumed that the thing would not work, so never actually bothered to try it.
Today, on a whim I dug the thing out (blew the dust off it) and plugged it in...
Linux recognises the device. Mandriva Linux Control Centre lists it as 'USB sound devices/USB Audio' with this information:
Description: USB Audio
Media class: Audio|Control Device
Bus PCI #: 1
PCI device #: 3
Vendor ID: 1054
Device ID: 12304
Also, in addition, KMix lists the device as an available mixer, correctly identified as a Sound Blaster MP3+
But, there is no sound to be heard...
It would make my day if I could get the thing to work, so any thoughts or suggestions would be very appreciated.
This is what I've discovered myself by trial and error.
Cold starting or rebooting with the MP3+ in place makes no difference. The device comes up as recognised, but with no sound output present.
The Creative SoundBlaster MP3+ USB audio device definitely DOES work under Linux.
But for some reason it will not co-exist with on-board sound if that is enabled. Disable on-board audio in the bios so that the usb device is the ONLY audio device present on boot and it works.
Sound quality is ok-ish, though glitches somewhat.
Re-enable on-board audio and the MP3+ device ceases to work once again. (Even though all indications are that it should, as outlined in my previous post at the start of this thread.)
Am I, therefore to assume that Linux can only handle one audio device at a time? Is there a workaround to make it use more than one, or a method to switch between devices, as I would be able to if I were running Windows? Or is this a known limitation that I just wasn't aware of?
I know that linux has a bit of a problem with multiple sound devices but I don't believe it is impossible. My USB headset is listed as a sound card even though it is not. I have to change the device in the mixer then reboot or logout and log back in to get it to work. I should mention that it only works on my Ubuntu box. SuSE could'nt get it work and I haven't figured it out yet on my Debian box. You may want to tell us your distrobution and whether you use KDE or Gnome or other and maybe someone else can jump in here with a suggestion. I wish I could be of more help.
