Toshiba Tecra A8 without audio with Ubuntu 12.04

[LubnaH]

Hi all!

My problem is this:
No sound on a Toshiba Tecra A8 with this information about audio:
Intel Corporation N10/ICH 7 Family High Definition Audio Controller (rev 02)
0 [ Intel]: HDA-Intel - HDA Intel
HDA Intel at 0x42080000 irq 44
Advanced Linux Sound Architecture Driver Version 1.0.24.

I tried for weeks all the solutions that provide some forums and any of them have worked (reinstalling alsa, modifying the file alsa-base.conf on many ways, etc).

The only solution that i found in some forums and I haven't tried is to install windows and from there up the volume controls and then reinstall Ubuntu on a partition. This "solution" seems a bad one for me, basically because it's more than 7 years that I only work with ubuntu and I don't know from where can I start with installing windows.

If someone can help me I would be very grateful. I don't think on windows as a solution to solve a problem on linux, it would be almost as an exorcism to this poor Toshiba that on the rest of the things works perfectly.

Thank you in advance,
Salud!

First. Check your levels in alsamixer.

 alsamixer

Press F6 to select the correct soundcard.
Press F3 to show playback levels. F4 selects capture levels [or use <Tab>]
Use the left/right arrow keys to select and up/down arrow keys to change levels.
Go to "System>Preferences>Sound" and make sure the correct soundcard is default.

Next. Can you post the output of these terminal commands for me please:

uname -a
aplay -l
cat /proc/asound/version
head -n 1 /proc/asound/card*/codec#*

Terminal="Applications->Accessories->Terminal"
Please post text output using code tags.

Not that I think I can help you but perhaps some others can if you also post the output of those. Through the help of the function button in Windows does appear to be a good solution if you had it installed, sadly.

Hey! Thank you very much for trying to help me.

Here is the output of the commands you told me

pornoterrorista@pornoterrorista:~$ uname -a
Linux pornoterrorista 3.2.0-26-generic #41-Ubuntu SMP Thu Jun 14 16:26:01 UTC 2012 i686 i686 i386 GNU/Linux

==> /proc/asound/card0/codec#0 <==
Codec: Realtek ALC262

==> /proc/asound/card0/codec#1 <==
Codec: LSI Si3054


When I go to alsamixer all the level are up (but marking 00) except the "speaker", that is on 00 and there's not possibility of moving it up (or I don't know how to do it).
I have the right card selected on alsamixer but on Ubuntu 12 System>Preferences>Sound there's no way to select the card, there's no option for it.

Thanks for your help, I would love to try to arrange this without privative software help!
