Toshiba Satellite A200 and A205 series have problem with I ts sound when you install Ubuntu.
Because, the Realtek 268 codec from Intel ICH7 with Realtek chipset doesn’t support Ubuntu. So, if you want to get your sound back, you have to replace the codec with latest version from ALSA driver.
You can check your codec by typing:
taufanlubis@toshiba:~$ cat /proc/asound/card0/codec#0 | grep Codec
Codec: Realtek ID 268
taufanlubis@toshiba:~$
Check your sound card:
taufanlubis@toshiba:~$ lspci
……
00:1b.0 Audio device: Intel Corporation 82801G (ICH7 Family) High Definition Audio Controller (rev 02)
…..
taufanlubis@toshiba:~$
Most modern distros come with soundcore compiled as a module. You can check it by typing:
taufanlubis@toshiba:~$ modinfo soundcore
filename: /lib/modules/2.6.22-14-generic/kernel/sound/soundcore.ko
alias: char-major-14-*
license: GPL
author: Alan Cox
description: Core sound module
srcversion: 548AA54AF08207316C104F8
depends:
vermagic: 2.6.22-14-generic SMP mod_unload 586
taufanlubis@toshiba:~$
If this command returns that you have this module, then you don’t need to recompile your kernel.
There few steps you need to follow:
Step 1. Download the latest driver from ALSA project.
ALSA (Advanced Linux Sound Architecture) provides audio and MIDI functionally to the Linux operating system. The web page address is: www.alsa-project.org
There 3 files that you have to download, alsa-driver, alsa-lib and alsa-utils.
alsa-driver-1.0.15.tar.bz2 2.6M
alsa-lib-1.0.15.tar.bz2 776K
alsa-utils-1.0.15.tar.bz2 991K
These are the latest update when I downloaded it.
Step 2. Copy the 3 files to alsa directory in /usr/src
taufanlubis@toshiba:~$ cd /usr/src
taufanlubis@toshiba:/usr/src$ sudo mkdir alsa
taufanlubis@toshiba:/usr/src$ cd alsa
taufanlubis@toshiba:/usr/src/alsa$ sudo cp /…your_alsa_location.../alsa-*
Step 3. Install the alsa-driver package
I suggest to use both bunzip2 and tar, not tar only.
cd /usr/src
mkdir alsa
cd alsa
cp /downloads/alsa-*
taufanlubis@toshiba:/usr/src/alsa$ sudo bunzip2 alsa-driver-1.0.15.tar.bz2
taufanlubis@toshiba:/usr/src/alsa$ sudo tar -xf alsa-driver-1.0.15.tar
taufanlubis@toshiba:/usr/src/alsa$ cd alsa-driver-1.0.15/
I suggest to use root access level not sudo because I got problem when I used sudo.
taufanlubis@toshiba:/usr/src/alsa/alsa-driver-1.0.15$ su root
Password:
root@toshiba:/usr/src/alsa/alsa-driver-1.0.15# ./configure –with-cards=hda-intel –with-sequencer=yes ; make ; make install
Step 4. Set permissions for dsp, mixer, sequencer and midi (if you use it).
root@toshiba:/usr/src/alsa/alsa-driver-1.0.15# ls -l /dev/dsp /dev/mixer /dev/sequencer
crw-rw—- 1 root audio 14, 3 2007-11-25 21:09 /dev/dsp
crw-rw—- 1 root audio 14, 0 2007-11-25 21:09 /dev/mixer
crw-rw—- 1 root audio 14, 1 2007-11-25 21:09 /dev/sequencer
root@toshiba:/usr/src/alsa/alsa-driver-1.0.15# chmod a+rw /dev/dsp /dev/mixer /dev/sequencer
Step 5. Install alsa-lib package
root@toshiba:/usr/src/alsa/alsa-driver-1.0.15# cd ..
root@toshiba:/usr/src/alsa# bunzip2 alsa-lib-1.0.15.tar.bz2
root@toshiba:/usr/src/alsa# cd alsa-lib-1.0.15
root@toshiba:/usr/src/alsa/alsa-lib-1.0.15# ./configure ; make ; make install
Step 6. Install alsa-utils package
root@toshiba:/usr/src/alsa/alsa-lib-1.0.15# cd ..
root@toshiba:/usr/src/alsa# bunzip2 alsa-utils-1.0.15.tar.bz2
root@toshiba:/usr/src/alsa# tar alsa-utils-1.0.15.tar
root@toshiba:/usr/src/alsa# cd alsa-utils-1.0.15
root@toshiba:/usr/src/alsa/alsa-utils-1.0.15# ./configure ; make ; make install
Step 7. Insert the modules into the kernel
root@toshiba:/usr/src/alsa/alsa-utils-1.0.15# modprobe snd-hda-intel
root@toshiba:/usr/src/alsa/alsa-utils-1.0.15# modprobe snd-pcm-oss
root@toshiba:/usr/src/alsa/alsa-utils-1.0.15# modprobe snd-mixer-oss
root@toshiba:/usr/src/alsa/alsa-utils-1.0.15# modprobe snd-seq-oss
Step 8. Adjust your sound card’s volume levels
You can quit now from root access level.
root@toshiba:/usr/src/alsa/alsa-utils-1.0.15# exit
exit
All mixer channels are muted by default, so you must unmute the channels. You can use alsamixer from alsa-utils package.
taufanlubis@toshiba:/usr/src/alsa/alsa-driver-1.0.15$ alsamixer
Step 9. Setting up modprobe and kmod support
If you don’t have /etc/modules.conf, just create a new one.
taufanlubis@toshiba:/usr/src/alsa/alsa-driver-1.0.15$ cd /etc
taufanlubis@toshiba:/etc$ sudo gedit modules.conf
#Alsa portion
alias snd-card-0 snd-hda-intel
alias snd-card-1 snd-cmipci
options snd-cmipci id=”firt” mpu_port=0×330
# OSS/Free portion
alias sound-slot-0 snd-card-0
alias sound-slot-1 snd-card-1
Create alsa file in /etc/modutils/
taufanlubis@toshiba:/etc$ cd modutils/
taufanlubis@toshiba:/etc/modutils$ sudo gedit alsa
#ALSA portion
alias char-major-116 snd
alias snd-card-0 snd-hda-intel
#module options should go here
#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
Step 10. Reboot your computer.
You will get the sound after you boot your computer.
Now, you have a new sound Codec for your sound card.
taufanlubis@toshiba:~$ cat /proc/asound/card0/codec#0 | grep Codec
Codec: Realtek ALC268
taufanlubis@toshiba:~$
Happy trying.
