Realtek sound issue please help

I have a realtek HD sound card in my Laptop (see sig) and a while ago I noticed that when ever a sound would play there would be a a high pitch sound thats obviously created by the inner working of the laptop and sent through the sound card into the speakers and that would go on for a couple seconds then I would hear a pop and the sound would shut off until something triggered another sound like clicking back a folder or whatever. Then the other day the sound card did not stop putting out that sounds thats not too loud, but very annoying. The sound still sounds great when something is playing, but if there is nothing and my speakers are on I can hear all these annoying sounds like USB power, the hard drive spinning and everything through the speakers and the sound card doesn't cut it off anymore. I hope you guys know what I am talking about and if anyone has a suggestion please let me know. I already tried the generic drivers and the most up to date ones from the realtek site, but it doesn't seem to be a driver issue. For now I am just turning off my speakers when I am not listening to music, watching or playing something, but it is kind of a pain.

 

HI
Tell me what laptop you have? can't read from that sig.
If you have old lappy you will encounter issues with new latest realtek audio drivers
go on realtek web go to downl hd audio section there will be check box and agree before that read and learn what they saing to downloaders !
I had old laptop and only old hd driver worked properly !! till 1.82 this version- 1.83 was already bad.. In right speaker I heard noise and cracking ...
Find 1.82 or 1.81 and you might be all right !

 

I have an Asus G50Vt-A1 its not brand new its 9 months old.

The only driver on the realtek site is R2.30 and thats what I have installed.
