Windows 7: Realtek, Windows 7 64RTM Crackle/static/popping

It's amazing that Acer would be so clueless about this. It appears there is no solution for now until the company responsible (whoever that might be) decides to fix it. It would sure be nice if they stepped forward and explained the problem so that we could stop pulling our hair out trying to resolve it. For now, the only fix seems to be to reboot. I'm thinking a reboot script in task scheduler to run each morning at the same time. (a command such as "shutdown -r -f -t 10" in a bat file).

There's another good thread on this problem here: Music flickers/crackles in Windows Media Player when browsing the Internet

I have the same issue with the sound. Whenever i type or surf on the internet with my wireless keyboard/mouse it starts to make those sounds. If i dont use it, im perfectly fine. My keyboard set is 6 yrs old without window 7 driver. Would switching the keyboard/mouse with window 7 compatable eliminate the sounds? Thanks!.

FYI everybody, Your BIOS handles IRQ assignments during POST, they get reassigned by the drivers during bootup that are then used by Windows 7, Disabling PNP-OS support will prevent the drivers from reassigning the IRQ.

Well after using my laptop for 8h the spikes on DPC latency checker started going all red about 10000us and sound started to crackling then I turned the Utorrent out and the CPU went to 1000-2000us.
And the sound was normal again, someone has written about it some pages ago.

Wow, I've tried several live cd distributions of linux and none of them work that well. I'm afraid that if I actually install them they will have the same bugs and incompatibilities. I guess I'm stuck with windows 7

I came across two interesting items on the web:

Aspire 5739g speakers crackle

Aspire 5739g speakers crackle

And a possible hardware fix for the other laptops. Even though this fix is specifically for the Dell. The fix is using electrical tape on the metal housing of the audio jacks.

This started happening to me when i installed a program called pc matic, it updated my audio driver and i get the same issues as you do but propberly worser as it makes a loud sdcreaming noise when it gets past half way (half way to maximum sound)

I simply rolled back my driver and it worked fine

For me this doesn't seem to be a windows 7 problem. I installed linux mint and it does the same thing with that after awhile. Also disabling graphics cards and wireless adapters doesn't effect it, it will still do it after awhile. The intel graphics actually works better though for some reason.

I need to get a lawyer or something so Acer will send me a working computer, or I could just throw it out. I'd hate to get rid of something I spent so much on. It probably would be better for my mental health though if I just smashed the dang thing. Acer and their runarounds and their joke of a repair center.

I complained on reseller ratings and the store I bought it from basically told me I'm just SOL again. I'm beginning to think a lot of the positive ratings on that site are fabricated by the stores. There's big discussion about that on the boards there.

I was browsing this topic and many others for a solution to this problem, Nothing aforementioned solutions have fixed this problem. I was looking through my sound properties and came across an "Exclusive mode" option for the sound device, and since disabling it (about 6 hours ago) i have yet to hear cracking, popping or static. To find this option, Right click on your Speaker icon in your taskbar, go to Playback devices, Click on your speakers, and click Properties. Under the advanced tab there should be a check box stating "Allow Applications to take exclusive control of this device" uncheck that and try to re-produce your cracking/cackling/popping sounds.

Hope this helps.
