 |
|
Heya all,
First I'd like to introduce myself, since ths is my first post in the gentoo forums. I've been running linux for about a month, and gentoo in particular for about 2 weeks. I've become something of a linux cheerleader having converted nearly 10 of my friends to our 'cause'. This has also made me pretty good at *nix!  (since I usually end up setting up their box) Anyway, to get down to business..... After trawling through the forums for some time now (and after dealing with my own problems) I thought i'd write down my own experinces with getting my Audigy 2 working, the easiest way i've found possible.
Things you'll need:
1) Willingness to recompile your kernel and use development sources.
2) The time to do #1
Getting started
1) First off, you need to emerge kernel sources 2.5.69 or greater (for built in alsa support) You can do this by emerging development-sources, mm-sources or any of the other packages in portage that use developmental kernels. I prefer the development-sources myself. (i'm running 2.6 at this time)
Note: If you already have 2.5.69+ kernel sources merged, you can skip to step 2
| Code: | | emerge development-sources |
If there is a particular kernel you would like you can merge it by using e-build manually. Lets say you wanted development-sources 2.5.73.
| Code: | cd /usr/portage/sys-kernel/development-sources
ebuild development-sources-2.5.73.ebuild merge |
2) Now that we have our sources downloaded and merged its time to configure our kernel. If you know how to do this already, skip down to the part about configuring for ALSA.
To start, for greater explanation of any of the following steps in building and configuring a kernel please visit this link
If you'd just like to use your current configuration as a base for the new kernel enter the following:
| Code: | cd /usr/src/linux-beta
make oldconfig |
Be prepared to say yes or no to whatever new options are presented in the newer kernel. Just press enter for defaults if you're not sure what something does. You can change it to your liking later in menuconfig or xconfig.
Now enter kernel config
(text based program)
or
(X based program)
Configure it to your liking, when you get to sound. Make sure you enable it. Enter the sub menu and enable the Advanced Linux Sound Architecture. Enable Sequencer support if you'd like midi support. Enable OSS API emulation for OSS support, check all the other OSS related modules if you'd like them as well. Scroll down to PCI devices, and enter the submenu. Select EMU10K1.
Note:You may compile these as modules if you wish, I just prefer them built-in.. my kernel is bare bones besides alsa... so it doesnt bother me
I have included my settngs for refrence:
| Code: | #
# Sound
#
CONFIG_SOUND=y
#
# Advanced Linux Sound Architecture
#
CONFIG_SND=y
CONFIG_SND_SEQUENCER=y
CONFIG_SND_OSSEMUL=y
CONFIG_SND_MIXER_OSS=y
CONFIG_SND_PCM_OSS=y
#
# PCI devices
#
CONFIG_SND_EMU10K1=y |
After you have configured your settings and the ALSA settings exit out of config, making sure to save. We can now build the kernel. If you are new to 2.5.x and greater kernels... you'll notice you no longer have to 'make dep'
| Code: | | make clean bzImage modules modules_install |
This doesnt take more then 5 or 10 minutes on my computer, (2ghz w/2 gigs of ram) but if you got anything older get ready for a wait. I reccomend 'Grand Theft Auto 3: vice city' for PS-2
After it's done compiling you must copy the boot image to your boot partition. Make sure to mount it first!!
| Code: | mount /dev/boot /boot
rm /boot/bzImage && cp /usr/src/linux/arch/i386/boot/bzImage /boot |
I always run LILO/GRUB again after for good measure, not sure if you have to, but its something i do and i've never had any problems with 'unable to decompress kernel' crap since i've started.
You're all set now, reboot to run up the new kernel. After you're back up and running you need to emerge alsa-utils.
This builds alsamixer, the application used to unmute your rear channe (if you have mutiple channels such as myself) To do this, run alsamixer and adjust the settings as you see fit.
That's about it, enjoy the sound! This may not be the best way to accomplish this, but it worked for me.. (and i like the newer kernels so it was cool with me) If you have any questions/suggestions/additions feel free to reply. Hope I helped someone!
