I general dont upgrade your drivers unless something is wrong, you may end up causing more problems then fixing anything. If it works dont fix it.
Well I mainly am looking for new drivers cause my audio sounds choppy since last week.
And with choppy I mean that it sounds like a ''pop'' each time something loud plays, I am not sure if I haven't noticed this before (it's been 3 years now) or that there is something wrong the drivers, worth a try though.
What are you trying to do with your sound are you just using sound to play audio or are you using it to record audio with also? when your speakers make the noise are you playing cd's or are they recorded sounds or do you have musical instruments plugged into an input in one way or another? Are you using external speakers to monitor audio or headphones?
