Red face I have No Sound

I have a Toshiba satellite, L30. I've tried installing Both Ubuntu 7.10 and the new release of Ubuntu, The Latest Mandriva, Fedora and Open Suse. All of these distros have no sound.
Somebody help me coz I really want to trash Windows.

When I execute /sbin/lspci | grep -i audio,
I get
ATI Technologies Inc SB450 HDA Audio (rev 01).
Then on running lspci, I get

Hi. Do you know what chipset your soundcard uses? If you do not know this information, you can get it by running
/sbin/lspci | grep -i audio
That should work on any distro.

I had the same problem when I installed OpenSUSE 10.3 three months ago.
I have solved it by installing new ALSA drivers.

See here:

maybe this will help

The first thing to check is if the volume is turned up, open a terminal and type alsamixer check the main volume and make sure it's up, also look at the bottom of the bar and make sure it's not mutted. If it is press the m key while it is highlighted and it will unmute it. Use your L&R arrow keys to navagate the menu and the Up&Down to change levels. Then press the Esc. key to exit.

If everything is ok then run the alsa configuration util su into root, then type alsaconf and follow the instructions after its done it should prompt you to check your alsamixer for volume again.

had problems after running `alsaconf`

I had no sound after I runned alsaconf

unload unneeded drivers and load your needed driver

# echo "soundcore ac97_bus snd-intel8x0" | xargs modprobe
# modconf

now don't run `alsaconf`, perhaps you want oss emulation to access '/dev/dsp' some older applications may require it

# echo "snd-mixer-oss snd-pcm-oss" | xargs modprobe

note, I saw that there exists drivers for your notebook toshiba-acpi and toshiba in kernel/drivers/char, to detect if loaded try

# lsmod | grep toshiba

what is your Linux distro? You have mentioned you have tried with several (Ubuntu, Fedora...)
In all cases first I will install the latest version of ALSA.
It really worked for me.

OpenSuSE 10.3 comes with ALSA 1.0.14.
I installed ALSA 1.0.15 and problem disappeared.

Please check my entry done on “Oct 31 2007, 09:53 AM”:

Follow the same steps.

If you install new ASLA , then reboot the system. I think there is no need to use ./alsaconf
In OpenSUSE you can work with YaST and this should be enough.
