I have a HP Pavilion dv6 1340ss with Linux Mint 13 Mate 64-bits edition. My laptop has a lot of Fn keys (brightness, browser, lockscreen, sleep, mute, wifi...) All the keys works properly except the media keys (play/pause, stop, prev and next) But, if I press this keys the system recognizes them as you can see in this image:

Anyone knows how to solve this? I tried on Banshee's preferences but the extension for these keys was activated
I have a photo of the keyboard too:

I'll be glad if someone can help me. Thanks!
