try running:

echo "options snd-hda-intel model=dell-m6" | sudo tee -a /etc/modprobe.d/alsa-base.conf

Reboot to test

Thank you for the answer but it did not work.
When I go the sound system I can see that there is no hardware identified.

It is not recognising the sound-cards I think.

Then run:

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

Change the model in the last line from dell-m6 to dell

If that doesn't work, try changing the model from dell to laptop

HTH

Ok. but after changing and saving it do I have to reboot or refresh the alsa-base.conf ?
Thanks.

Yes reboot between to test

I changed&salve&reboot in both cases and it still didn`t work.
Thanks.

yeah. As I said before I tried both but it did not work.
Thank you.

I would try "dell-laptop" for the model= keyword. See the full list (your codec is equivalent to Conexant 5066)here: http://git.alsa-project.org/?p=alsa-kernel.git;a=blob_plain;f=Documentation/sound/alsa/HD-Audio-Models.txt;hb=HEAD

Also, a newer kernel module might help: https://code.launchpad.net/~ubuntu-audio-dev/+archive/alsa-daily/

Thank you I will try that.

I tried this solution but it did not work. I`ve been trying other and did work either.
I don`t know what else I can do.
