Bug Description
Binary package hint: linux-source-2.6.20
Hi,
since i installed ubuntu i hod this bug, and since there was no one who reported it here, i am doing it :)
The problem is that when you plug in a headphones jack, speakers are not unmuted.
The problem is well described here on the wiki for this laptop : https:/
And there is even a beginning of a patch on the alsa bugtracker : https:/
I applied this patch on alsa 0.1.14rc2 and installed only snd-hda-intel and it is working great.

I have the same issue on a Lenovo 3000 V100 running feisty, and google search suggests that other laptops using the chip have the same issue.
Any chance this could be fixed in feisty?
