I installed Ubuntu 12.04 on my Asus k55vd laptop this morning. Laptop is now dual booting, with Windows 7 on the other partition. When running Ubuntu, sound plays out the speakers, but when I plug in my headphones, the speakers turn off (as they should) but nothing is played through the headphones.
This does not happen on the windows side of the partition. I've ran the information test with Alsa. The results can be found here:
Any help at all would be very much appreciated.
