Hi,

Your tablet-PC indeed seems not to work very well with Ubuntu. This is pretty recent hardware, and the developers always need a bit of time to make it run properly. It seems that some problems can be fixed, but you need to understand how Linux system works to make it run (Google may help you, see http://mirosol.kapsi.fi/tx2020/tx2000howto.htm or http://ubuntuforums.org/showthread.php?t=686363 for instance). Otherwise, it is probably worth checking with the next version of Ubuntu (planned for October) if things have improved.

Bug #377435 is about the touchscreen (other similar bugs are known: bug #357709); I cannot find anything about the sound card nor the webcam for this particular model.

Thanks Arnaudus, But really like this Ubuntu so I wish my sound card atleast should work, I donot care for touchscreen, I donot use that feature much, but soundcard/webcam drivers atleast put me on track, please suggest anything that is possible to make that happen.

Hi,

OK, then let's try to get the sound working.

First, can you confirm you are using the very last version of Ubuntu (9.04)?

Then, it would be easier to look for answers if you knew the model of the sound card. Open a terminal (Applications -> Accessories -> Terminal) and type:

lspci

The sound card is there, named like "Audio device" or equivalent.

Finally, I have found a forum thread in which someone pretended to have fixed the sound problem easily : http://ubuntuforums.org/showthread.php?t=686363&page=2 . You can try this procedure:

In a terminal, type

sudo gedit /etc/modprobe.d/alsa-base

This will ask for your admin password and open a file. Go to the end of the file, and add exactly:

options snd-hda-intel index=0 model=3stack position_fix=0 single_cmd=0

Then save and restart the computer. This looks a bit magic (I don't really understand what it is supposed to do).

If it does not work, a useful link can be the official Ubuntu troubleShooting guide : https://help.ubuntu.com/community/SoundTroubleshooting . A bit technical, but it may help to identify exatcly what is the problem.

Hope this helps!

Hi,

Please try the solution procedure from forumuser gali98 at this location:

If you are using Ubuntu 8.04 or Ubuntu 8.10 you need to edit the file

/etc/modprobe.d/alsa-base

If you are using Ubuntu 9.04 you need to edit the file

/etc/modprobe.d/alsa-base.conf

Hi Arnaudas,
The output of lspci is as under : (truncated) - It shows my Audio device, but I have no sound
00:13.2 USB Controller: ATI Technologies Inc SB700/SB800 USB EHCI Controller
00:14.0 SMBus: ATI Technologies Inc SBx00 SMBus Controller (rev 3a)
00:14.1 IDE interface: ATI Technologies Inc SB700/SB800 IDE Controller
00:14.2 Audio device: ATI Technologies Inc SBx00 Azalia (Intel HDA)
00:14.3 ISA bridge: ATI Technologies Inc SB700/SB800 LPC host controller
00:14.4 PCI bridge: ATI Technologies Inc SBx00 PCI to PCI Bridge
00:14.5 USB Controller: ATI Technologies Inc SB700/SB800 USB OHCI2 Controller

I tried the first solution - The magical one but it did not happen in my case, no sound after restart too. i have version 9.04 where the file found was
sudo gedit /etc/modprobe.d/alsa-base.conf

(is this the file to modify - you wrote only alsa-base which was not there)
The following are the last 3 lines in alsa-base.conf, please let me know if these are correct

# Keep snd-pcsp from beeing loaded as first soundcard
options snd-pcsp index=-2
options snd-hda-intel index=0 model=3stack position_fix=0 single_cmd=0

I have tried this too but that too didnot work

# Keep snd-pcsp from beeing loaded as first soundcard
# options snd-pcsp index=-2
options snd-hda-intel index=0 model=3stack position_fix=0 single_cmd=0

Thanks for the help, please keep looking --
