Realtek AC97 Audio + Fedora Core 3

furtivefelon · 02-19-2005, 03:05 PM

hello

i have a labtop that uses Realtek AC97 Audio (as seen in windows XP devices page), however, when i installed linux, everything else works fine, except for the sound card, so i have no idea how to config the sound to work.. my computer is a eMachines M5410 AMD Sempron 2.0GHz Notebook..

thanks alot for helping

ok, i have found the driver here: http://www.realtek.com.tw/downloads/...&Software=True

the downloaded is apparently source code form, can someone tell me how to compile the source code into the kernal? thanks alot

i've come as far as this:

Step 4. Edit your /etc/modules.conf or conf.modules depending on the distribution

(Please refer to the attached modules.conf)

where is the equivalent modules.conf on fedora core 3? i can find it.. thanks alot!

Sorry, been busy wth other stuff.

First, all that source code does is build you a copy of snd-intel8x0, which you already have. As it says, the code was copied from the ALSA site.

As to the module def.s, here's what mine looks like (and my AC'97 sound is working fine):

Code:

$ cat /etc/modprobe.conf
alias eth0 8139too
alias snd-card-0 snd-intel8x0
options snd-card-0 index=0
options snd-intel8x0 index=0
remove snd-intel8x0 { /usr/sbin/alsactl store 0 >/dev/null 2>&1 || : ; }; /sbin/modprobe -r --ignore-remove snd-intel8x0
alias usb-controller ehci-hcd
alias usb-controller1 uhci-hcd
# I2C module options
alias char-major-89 i2c-dev
alias char-major-195* nvidia
options nvidia NVreg_ModifyDeviceFiles=0

Just for the heck of it, I'm going to try their suggestion and add

Code:

# ALSA portion
alias char-major-116 snd
alias snd-card-0 snd-intel8x0     
# OSS/Free portion
alias char-major-14 soundcore
alias sound-slot-0 snd-card-0
# card #1
alias sound-service-0-0 snd-mixer-oss
alias sound-service-0-1 snd-seq-oss
alias sound-service-0-3 snd-pcm-oss
alias sound-service-0-8 snd-seq-oss
alias sound-service-0-12 snd-pcm-oss

in there. Maybe then ALSA might work for me

Oh, note that the modprobe.conf file is in /etc/, and (of course) you need root access to edit it.

OK, now my /etc/modprob.conf looks like this:

Code:

$ cat /etc/modprobe.conf
alias eth0 8139too
alias snd-card-0 snd-intel8x0
options snd-card-0 index=0
options snd-intel8x0 index=0
#remove snd-intel8x0 { /usr/sbin/alsactl store 0 >/dev/null 2>&1 || : ; }; /sbin/modprobe -r --ignore-remove snd-intel8x0
alias usb-controller ehci-hcd
alias usb-controller1 uhci-hcd
# I2C module options
alias char-major-89 i2c-dev
alias char-major-195* nvidia
options nvidia NVreg_ModifyDeviceFiles=0
#
# ALSA portion
alias char-major-116 snd
#alias snd-card-0 snd-xxxx
# OSS/Free portion
alias char-major-14 soundcore
alias sound-slot-0 snd-card-0
# card #1
alias sound-service-0-0 snd-mixer-oss
alias sound-service-0-1 snd-seq-oss
alias sound-service-0-3 snd-pcm-oss
alias sound-service-0-8 snd-seq-oss
alias sound-service-0-12 snd-pcm-oss

and ALSA seems to be working.

I guess I should have gone to the ALSA web site and read a little more, eh?

(In my defense, I only use the sound system for basic stuff, and OSS was working fine for me, so why bother?)
