System becomes unstable and freezes when playing high sound

I have arch linux installed on my laptop and it works fine for all tasks. Except when I play some sound. If I'm listening to music and I increase the volume higher than 60% the applications starts to freeze, the load average rises and everything gets slow. It gets back to 'normal' if I pause the music or decrease the volume. If I use an external speaker that doesn't happen.
My computer is a dell inspiron 14 intel i5 2nd generation 4gb ram. It is a decent computer so I think we can say it is not a horsepower issue. (I'm not sure if I should be posting it under the hardware session but since it works fine with an external speaker I think we can exclude a software problem)

Any clues?

do you get any helpful output from from the dmesg command, while pumping up the volume?

have you tried updating the kernel/alsa drivers (assuming you are using alsa drivers)?

Yes I searched for any changes with the dmesg output but I got nothing different changing the volume. Here are the xorg and dmesg logs if you want to check at.

I'm using the kernel 3.3.4-1. Higher versions for some reason don't work well on my laptop. It becomes really and I had to downgrade. But everything else is on the bleeding edge.
