Realtek, Windows 7 64RTM Crackle/static/popping

Also having a similar problem, no luck with my own thread.

I just wanted to let everyone know that after reading multiple forums, etc, this one finally helped my solve the problem of crackling sound. I tried almost everything listed previously in this forum on my brand new Lenovo Ideapad Y450 (nvidia graphics card, realtek high def audio, etc) running windows 7. The last thing I tried was to change the advanced power settings in control panel. Under processor power management, I changed the minimum processor state to 100%, like previously mentioned in this thread and the popping/crackling sounds went away and stayed away. I then tried various settings to see what would happen. At minimum processor state of 30%, the noises came back, but anything above 40 and I had no sound problems. THIS WAS A SOLUTION FINALLY!!! Thanks to those who posted and try this if you have not already!

I had it set at 100% already. That wasn't the issue with mine. Acer has the computer now and I hope they actually fix it or give me a new one.

Similar problems here. The sound always has a bit of background fuzz no matter how many things I disable (or what I change on the hardware side) If I have no audio applications open except for one (or if I simply tick the volume slider with no audio apps open), I get this really annoying popping sound at the beginning and end of each sound, and if the sound clip/effect is too short I simply here a pop and nothing else. The popping issue disappears if I run Microsoft's default drivers. This is really annoying and I've tried everything to fix this problem with the exception of buying a new sound card (Which I really don't want to do; this is a Micro ATX motherboard with only 2 PCI slots and 1 PCI-E slot.)

I've...

-Tried a bunch of drivers, old and new.
-Disabled Cool 'N Quiet in the BIOS
-Disabled various power saving options
-Set my power plan to maximum performance, set cpu active maximum percentage thing to 100%
-Disabled hardware

I'm at my wits end on this and I guess I AM going to have to buy a new sound card. Ugh.

I'm running Windows 7 32-bit.

I've narrowed my problem down to a latency issue but I still can't fix the problem. I can't find that bad driver!

All of you shouldn't have to jump through hoops to eliminate this popping/crackling sound. It should be a simple driver installation. I don't have a solution but maybe we should make sticky thread with known motherboards and laptops that have popping/crackling sound so others will know what not to buy.

What makes it difficult to accept is that WinXP has worked perfectly well on the same hardware, at least for several of the posters here.

Well that was a silly solution I gave.

Has anyone tried disabling the onboard sound and installing a Creative Sound board or an external sound device?

Do you still hear crackiling when disabling the onboard sound?

belikexp,

I noticed one poster got rid of crackling-static by upgrading to the latest BIOS for his/her MB so it could be hardware related.

In your system specs you have Realtek AC97 listed, instead of the problem causing Realtek HD Audio.

AC97 is the older standard and I assume doesn't have all the surround sound options or high sample/bit-rates available?
