audio stutter

[Andrew Crome]

Every time I play audio in my web browser I get what can only be described as a stutter or hiccup, its very random, so not really sure if its related to firefox or not. My system is a Acer aspire XC_-603 1tb hard drive 4 g ram

the sound card and video card are integrated on the mother board so i cannot replace them.

its really annoying any assistance is greatly appreciated I'm no expert so my knowledge is pretty raw
