A8N32-Sli Deluxe onboard sound problem

I googled and searched the (Asus) forums and can't find any solution to the problem. There is one post of someone asking a question on a similar problem but no one answered him with the answer or any advice.

I sometimes use headphones for my computer to listen to music or watch a movie but there is a loud crackling and hiss whenever something is paused. I know that many people have complained the problem is when moving the mouse or something similar. But, mine is slightly different than that as it is a constant hissing/crackling regardless of what I'm doing. I can just be sitting there, doing nothing on the computer and the hissing/crackling continues. When I play music/movie with the headphones on, I don't hear it much until I hit pause on the media player.

I am using noise-isolating earphones. I also use them with my portable mp3 player and have no hissing/crackling then so I am sure it has to do with the motherboard onboard sound. I am hoping there is a solution because it is very annoying and unusable in the current state. I was thinking of getting another set of headphones (that fit outside of the ear) and hoping that the noise-isolating phones is a culprit. However, I am inclined to think it has to do with the Asus onboard sound. I updated the sound drivers and it didn't fix the issue. I really didn't want to be another Asus owner who can't figure out what to do and ends up buying a sound card. I would shell out for a sound card if that would absolutely fix the problem and I could be rest assured it would but if there are some things to try first, I'd rather do that before researching sound cards!

Please, anyone who owns this board or has had a similar problem, give me some ideas or explain what is wrong and how to fix it! The issue is really irritating and I need the option of headphones.

i had the same problem on my s939 a8n-e--nvidia nforce 4 ultra chipset.all i did was flash the bios and everything was back to normal.
so update ur bios!

I thought I had minimzed or solved the problem but it's back. Are you saying a sound card will solve the problem permanently because it's annoying me to the point I will have no choice but to sell the motherboard otherwise. If it took a sound card to solve the problem, then I would find the money and get one. But, I need to know for certain.

The Peter Chng proposed solution worked fine for a M3N-HT MB. Check it at
