stuttering/crackling sound

[Gabriel M Dragffy]

I experience crackling and stuttering sound in games. Games that I've
tried are Neverwinter Nights and Soldier of Fortune. Sound is perfect
when playing music, for example in totem, or watching movies and playing
most games i can get by apt. 

I'm a complete n00b and really don't know where to start debugging.
Apparently my sound card is built in to my laptop and is an Intel HDA.
