Toshiba NB100 no sound after upgrade

Asked by ianBentley

Sound was working fine when 8.04 was setup. After install for updated software the sound devices disappeared from list. No more sound. Have tried various fixes involving alsa drivers but to no avail.

When I do aplay -l - i get no soundcards found.
I cannot see in the bios where it can be disabled so i guess not that...

Toshiba web site has a fix for a soundcard fix but the link does not work...

Whilst the upgrade was going on some script files were changed which were claiming to be newer than the upgrade which i thought was unusual so i accepted so the scripts may now be wrong but do not know which ones or how to go backwards.

Help!!!

I found this link on the tosh web site
http://forums.computers.toshiba-europe.com/forums/thread.jspa?threadID=38079&tstart=0

and this fixed the problem, in essence i did the following

 Enter Terminal
type sudo mv /lib/modules/2.6.24-19-lpia/updates/sound ~/sound
press enter
enter password
press enter
type sudo depmod -a
press enter shut down note pad and restart

What did this do????? But it worked...... Please pass on

Unfortunatly this solution doesn't work.
I just updated (me fool!!!) to 2.6.24: result
- no sound
- no wireless

About sound, the subdirectory "sound" /lib/modules/2.6.24-19-lpia/updates/ doesn't exist (the "updates" directory is empty.
I have tried even patch suggested in Bug #298607 (https://edge.launchpad.net/%7Ejouston-huang/+archive/ppa/+files/nb100-sound_1.09_lpia.deb), but it doesn't not work.

Of course toshiba doesn't give any kind of support

It there anybody who solved this thread?

I tried all sorts of things even shouting at the computer.!!!!

Best answer I have is

1) Backup your data
2) Note which apps and add-ins you have loaded
3) Install Ubuntu V10.04 Notepad version (You need a (good) friend to download and put on a memory stick)
4) Forget Toshiba.

It installs OK and sound etc all works.

I tried to install 10.4 from a memory stick...
BUT unfortunatly BIOS (ver 1.10) doesn't work properly, and the machine is unable to load OS from USB (I tried the same stick on another laptop and works perfectly).
Then I tried to update BIOS.. but upgrade file found on toshiba website (after a VERY long search) for version 2.1, is not working (I've checked: I'm not the only one). I've been noticed that is enough first kernel update to make BIOS update impossible from Ubuntu. The only way is... to install from USB stick (it is not a joke!).
I agree to forget Toshiba, since they "certificate" such a bad product (bugged bios in a brand new machine, OS going in jeopardy for a simple automatic update, impossibility to upgrade OS....), but I still have this netbook and would like to make it work!
Finally I just modified Grub and back to former kernel!
Some more suggestions?

Hi
Have you seen this before? Extract from Toshiba plus some files which I have a copy of.....

If you need them then let me have an email address to send them to as this forum doesn't like file postings...

Due to some changes of internal core components in the linux operating system, it´s not possible anymore to update the BIOS within a running linux system after performing a system wide update.

A special update procedure needs to be applied to update the BIOS to the latest version and you will need a USB flash memory also called "USB stick". (attention: size of the stick does not matter!)

The procedure is like following:

Boot the linux system.
Once the linux system has started, copy the downloaded files "usb-imagewriter_0.1.3ubuntu1_all.zip" and "ARXXX.zip" from below to a folder on your harddrive.
Uncompress the "usb-imagewriter_0.1.3ubuntu1_all.dep" file from the "usb-imagewriter_0.1.3ubuntu1_all.zip" to a folder on your harddrive.
Double click on the file "usb-imagewriter_0.1.3ubuntu1_all.deb"
Click on "Install Package" in the upcoming window.
Enter the password of your user account in the next window to confirm the installation.
The installation will now finish. Close the window to proceed with the next step.
Attach the USB flash memory to a free USB port of your NB100.
Uncompress the "ARxxx.img" file from the "ARxxx.zip" to a folder on your harddrive.
Open "Applications" -> "Accessoires" -> "ImageWriter"
Enter the password of your user account in the next window.
Select "ARxxx.img" from the folder where it was uncompressed to.
Select the USB-memory as the target destination for the image.
Click on "Write to device".
Restart the NB100 after the image was sucessfully copied to the USB flash memory.
Press F12 during the "Toshiba" logo to bring up the boot device list.
Select the "USB memory" to boot from.
BIOS will be updated. Do not power off your machine during the BIOS update, otherwise your BIOS will be corrupted!!
The machine will be restarted automatically after the BIOS update.
Please go afterwards to the BIOS setup and set everything to default to ensure a proper function of the machine.

Thank Ian, but I tried already.... tha main issue was exactly that "older" BIOS can't read USB on boot (if I wanted to upgrade to 10.4 or anything else), and in this manner you need to boot from USB... it is ridicolous

Thanks, I think the only manner is to find a way to update BIOS through Linux, if possible. Otherwise I will stalk local toshiba until they find a solution!
