Realtek, Windows 7 64RTM Crackle/static/popping

Well, W7 x86 installation didn't fix it either.

This really looks like a hardware problem now

Like NM89, I was able to solve this problem using the DPC Latency Checker others have mentioned (downloaded from DPC Latency Checker). In my case it was my PCI wireless adapter causing the latency.

Lots of people here have solved this problem by enabling or disabling different programs since we all have a Windows 7 driver issue causing this, but using that latency tool should track down which device it is (instead of manually trying every individual solution other folks have tried.)

I'm having the same problem, except mine is so bad there is no use in listening to music/Watching Videos I tried using the latency checker the post above me linked to, but I could not solve the problem. On the latency checker the max latency is 74485 microseconds. Adjusting a device (even if you enable it again) helps space out the lag time a bit, but it comes back to steady clipping soon.

I ran DPC as well to figure out the issue and as it turns out, it's the wireless network adaptor on my laptop. It wouldn't be so much of an issue if I didn't need to use it but being a laptop, I kinda do =/

Well at home I don't have internet other than tethering my phone to it until it's back up and running at least but regardless it still is a pain and i can't really snake an ethernet cable across the house either.

If you have IAANTmon.exe running on your computer; try and disable that completely. That worked for me and I never had the issue afterwards.

If your still having problems you could try a usb audio card and plug in heaphones and that might work temporarily...

I have Win7 32bit and Motherboard ep-45-ds3p with Realtek audio card (integrated). It was Gigabyte Energy Saver. Now i remove it and the cracking disappear (my english is bad ). I also have ET6, and when i start it there is NO cracking sound. It was definitely stupid Energy Saver. Works for me.

I hope it was helpful (and understanding)

For ASUS notebook owners with realtek HD who have audio crackling problem, i think the source of problem is not realtek driver. Try to uninstall sonic master and ASUS Asio, i think that software is "the devil" :), mine has solved by unistall it.

I have a brand new Vaio S Series and spent about the last day and a half trying to figure out this problem... The crackling was apparent just about all the time: from startup to minor Windows-related tasks like adjusting the volume or browsing documents. The noises wre most apparent while using headphones. Using iTunes DID NOT result in crackling though, so it is probably a graphics or sound problem related to Windows.

I found that doing a Rollback of Realtek got rid of the crackling. I had updated it, and I assume the update was wonky or I didn't download a version compatible with my specific laptop. For now sound is working fine for me, but if crackling returns, I will do a follow-up post.

Thank you to others on this thread who also gave advice about rolling back devices through Device Manager. That's how I got the idea.

Nevermind. Still doesn't work
