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.

After doing an apt-get update, the next time I rebooted new audio hardware was detected. I have onboard audio and have been using the default audio driver until now, and I am unaware of what brand/name the audio is so I allowed it to install the other drivers. Now I have no sound, how can I get back to the default audio?? The only settings under Sound dont help me.... thanks in advance (this question has definetly been asking but after googling I cant find it, so a simple link without a flame would be good ;-D)

hi em4853, welcome to lq. could we see the output of /sbin/lspci -v, and lsmod please? something else to look at is your mixers, if the system has reconfigured the card w/new drivers, you'll probably need to run a mixer and unmute your sound.
Many of the posts I have read reguarding audio drivers have mentioned unmuting using ALSA but I cannot find more information on this nor find it if it is default RH9 (whereis ALSA) , any random information would be greatly appreciated (this is clearly in teh Linux - Newbie section),The relevent info you requested:
# /sbin/lspci -v
00:02.7 Multimedia audio controller: Silicon Integrated Systems [SiS] SiS7012 PCI Audio Accelerator (rev a0)
Subsystem: C-Media Electronics Inc: Unknown device 0300
Flags: bus master, medium devsel, latency 64, IRQ 11
I/O ports at dc00 [size=256]
I/O ports at d800 [size=64]
Capabilities:  Power Management version 2
(C-Media is the correct company, I didnt remember until now)
however, it looks as though an audio module is loaded. try running aumix and unmuting volume there. if that doesn't work, then the link above to the alsa drivers should get you going. the instructions are pretty clear so i'll just walk you thru the configuration process. once everything is installed you'll run
$alsaconf <this should give you the option to configure the card> when that's finished you'll run
$alsamixer <unmute anything that looks important by pressing the m key on your keyboard, you may also wish to set volume levels by using your arrow keys, "up,down",> once you're satisfied w/those settings you'll hit escape to exit, this should bring you back to the prompt, once there, you'll run
$alsactl store <this will save your configuration and settings across a reboot>
When i try to compile alsa the ./configure works but when i try to do make it just compiles indefinetly (the same files over and over) with the error "EISA_BUS" redefined.... what should i do?! It would be better if i could somehow revert to the original default drivers that worked fine ;-)
(I have kernel-2.4.26-1.ll.rh90.ccrma)
edit: the same thing happens if i try to make in the kernel source ( same error: warning: "EISA_bus" redifined , and it compiles the same thing over and over with the same error)
I can compile the source by doing each step (make clean, make .... make install) but when I try to compile from the alsa folder it doesnt work....... any suggestions about getting alsa to compile or if there is a way to go back to the default drivers (the latter is preferred) then please reply!
