Sound problem on Toshiba Satellite A60


Hello,
I've installed Kubuntu last week on my Toshiba Satellite A60 and almost everything is working flawlessly..except the sound card (a Realtek SL250).
After booting, I get a message telling :
--------------------------------------------------------------
Sound server information message
Error while initializing the sound driver
device : default can't be opened for playback (No such file or directory)
The sound server will continue, using the null outpout device.
-------------------------------------------------------------

I've installed all Alsa stuffs, but I have still the same message, and the sound isn't working..

Any body can help me?

During installation, there is usually a sound check - I take it y'ol' Satellite failed that?

lspci and dmesg should let you know if your soundcard is even seen. lspci should tell you the chipset - important.

Now - there are many drivers for Realtek audio cards - the trouble is that the designation "SL 250" dosn't seem to exist. Surely this should be "ALC250"

Anyway - while we're waiting - Toshiba for Linux is worth a look: http://linux.toshiba-dme.co.jp/linux/index.htm

I've just spend about an hour trying all the subtle tricks - nobody in these forums seems to have had trouble with the ALC 250 card, though there are other Toshiba sound issues with other cards (check them out - the solutions may work for you too).

There are no realtek sound cards in the HCL!

Your Toshiba is not listed in the HCL either, but other Satellites are - sound problems are a significant minority: it seems that ALSA does not support the soundcards - only OSS.

The ALC 250 is a AC97 chipset card - perhaps other AC97 chipset drivers will work? (A big deal seems to be made over the ALC 650... but see below.)

But I suspect that the OSS driver is blacklisted which is why you cannot get sound. Have you tried alsaconf?

There's tons to check out there. Get back with what you found.

If you want to have a go getting the card going under OSS instead of ALSA - you can find clues in this thread:
http://www.linuxquestions.org/questi...icle&artid=120

I know it isn't your laptop or your card, but the issue is similar and will have a similar resolution... one hopes.

(post edit)
Have you got oss-emulation going? See the alsa HOWTO:

Hello,
I'm sorry for that error, it was in fact a Realtec ALC 250 sound card..
I've tried lspci and dmesg and here is what it gives :

lspci :

dmesg:
t cp437.
NTFS-fs error (device hda1): ntfs_ucstonls(): Unicode name contains characters that cannot be converted to character set cp437.


I've tried to run alsaconf, but it tells "command not found"!

Can you tell me wich driver to install? And the difference between Alsa ans OSS?

Many thanks!

I've installed Ubuntu today, and now everything is working perfectly!!
I've followed the steps described in the Unofficial Ubuntu Guide to setup the sound, and now it's working without any problem. It seems to me that there are still some problems in the released version of Kubuntu..
Any way many thanks for your help Mr. Bridge!

Well OK and well done - if all else fails, try another distro ...
What I would have done is copied your lspci listing for your soundcard (under "multimedia") to the googlebar and hunted for drivers under that name.

Now I don't have to But it is a good general principle for anyone stuck for what to look for.

I just installed ubuntu 5.04 on my toshiba Satellite A60-120
and I understand that I have to install the Linux driver for this Realtek ALC 250 (which is part of a kernel module)
By sudo gedit /etc/modules
add the 2 following lines :
snd-atiixp
alsactl
and reboot your system...

It seems that many people have the same problem.
Here is the complete solution :

You have to follow the instructions on this page : http://ubuntuguide.org/#configuresoundproperly

And after add these lines to these files :

/etc/hotplug/blacklist :
snd-atiixp-modem
snd-atiixp

/etc/modules :
snd-atiixp

You also have to type "chmod 777 /dev/dsp"

Good luck!
