Thanks for filing this bug. I'm a little unclear how this relates to the Ubuntu One project. Maybe this should be assigned to Karmic (https://bugs.launchpad.net/ubuntu/karmic/+bugs)?

Hi, maybe you already tried this, but if still not, then check this page, there is a person who made his woofer work by using the following information:

The person who made the woofer work is speaking about it in the following page:

And the computer that he has is not the same model like yours, but maybe it could also help you. The person says that his model is toshiba x205-S9349

Another possible solution could be to compile the last drivers from alsa, downloading them from the svn.

I hope it helps!

Another possible solution:

You can enable 5.1 support in karmic by following the next information. I guess you will have no problem since I saw that you are coming from a spanish speaker country:

For the non-spanish-speakers, I will translate here the contents:

How to enable 5.1 sound in karmic
-------------------------------------------

1. Edit the file /etc/pulse/daemon.conf:

sudo gedit /etc/pulse/daemon.conf

and search the line that contains "; default-sample-channels = 2”. Replace it with “default-sample-channels = 6“. Please note that you MUST remove the semicolon character (;) in front of the line. This is really important, otherwise it will not work! After the change, save the file.

2. Restart pulseaudio server:

pulseaudio -k

3. Run alsamixer and change the number of channels. There is an option where you can see (2CH). Change it to 6 channels (6CH).

4. Test and look for the right positioning of your speakers. Use the following command:

speaker-test -Dplug:surround51 -c6 -l1 -twav

If you can hear every speaker right, then everything is ready.

Please let us know if this worked for you

Jigoita, hola he probado esas soluciones anteriormente y no me funcionaron, yo creo que debe ser problema del driver alsa que no tiene un soporte completo para esta tarjeta, el driver proporcionado por el fabricante realtek tampoco proporciona funcionalidad completa, y según investigue la tarjeta realtek alc268 no tiene soporte 5.1, esto en windows lo logran a traves del programa de manipulación del sonido que al activar la opción altavoz virtual se activa el subwoofer. aunque el equipo tiene 4 parlantes y un subwoofer integrado.
Pero esos problemas lo tenian con los laptop Acer y veo que añadieron la funcionalidad, y cuentan con la misma tarjeta de sonido que mi pc. sera que la gente que tiene el modelo de pc que tengo yo no usa linux, o no escuchan música, ni nada en el.

Maybe we should speak in English, cause everybody can look here at the comments, maybe looking also for a possible solution if having the same problem.

Perhaps you could try again the last drivers from realtek, here is the link:
http://www.realtek.com.tw/downloads/downloadsView.aspx?Langid=1&PNid=24&PFid=24&Level=4&Conn=3&DownTypeID=3&GetDown=false#High%20Definition%20Audio%20Codecs

You have to check a checkbox and wait until the page reloads, then press the button "next", then wait again, and then you get a page with all the drivers from realtek. Scroll down until the bottom of the page, find the linux drivers and download them.

I downloaded such linux drivers (which are from 3 december, hey this is just 5 days ago!) and found out inside a "Readme.txt" file which says that support for ALC268 is included. Maybe this is your release!!

I hope it helps. I can't help you much cause I don't have such sound system.
