Acer aspire 8930g crackling/high pitch sound windows7

Hi everybody, so... Last couple of days i'm sitting next to my new purchase... I bought: Acer Aspire 8930g it has NVIDIA geforce 9600m graphics card, 4gb ddr3, intel core2 duo processor T5800 2.0GHz, Realtek ACL889 sound card (i think it's integrated ini't?)...

Originally it comes with Win Vista (yeah right like i'm gonna use it...)
So I installed Win7... And the fun begins... I'm getting all kind of weird noises coming out of my left side speakers they are constantly changing. At the fresh start everything seems OK later on sound starts to pop, then crackle, then sounds sounds like a badly tuned FM radio, and then the most nerve-killing high pitch squealing. From the start it happens only when audio is coming out, later you don't need any audio it just kills your eardrums.

I went through loads of forums... loads of people seemed to have this problem, some of them solved it.

It's defo not a hardware problem.

Installing drivers for realtek... old ones, new ones,the ones before win7, original ones from cd didn't want to install... downloaded the same version... pointless!

Updated BIOS, no change.

Updated ACHI drivers made it worse ... slowed down the laptop, SMART error came up, degraded the drivers to previous ones...

I haven't seen any recent posts with this problem... last ones i saw were around 2010... What the shmuck... do they still live with this....

Saw some posts about power management... cant find anything in bios setup its empty on this laptop, so i just opt it out in windows, no difference.

Seen posts about putting other sound cards in... (not really good at these type of things ) buying a sound card would be my last option... it must be software problem...

Ticking "Immediate mode" doesn't help.

Well i might done some mistakes, can't remember any though... If you had this problem and sorted it out please give solutions.

It's a shame to have this problem on this lovely laptop, hope you guys gonna help me out...

 

Did you try going into device manager and uninstalling it also ticking the delete drivers option then reboot and let Windows search for the driver online?

Sometimes this works, sometimes it doesn't. Try to make sure all Realtek drivers are deleted from your system before doing it. I would also run CCleaner in between to delete all registry entries.

Diver Sweeper may also be of some help: http://phyxion.net/item/driver-sweeper.html

 

If you have win7

Go to control panel > hardware and sound > manage audio devices > recording > properties > uncheck "listen to this device"

Also go to playback > properties > enhancements > "disable all enhancements"

 

Niffcreature, if that is the fix, you rule and will definitely get a RP from me. I've admittedly lost knowledge about these legacy hardware problems. Was trying to give him some kind of other options though.
