I'm pretty much ready to give up and switch to a dedicated sound card... I've upgraded everything and nothing is working.

Does anyone else happen to have a PCI based wireless NIC in their system as well?

Me Actually. Some Edimax or another (not at home right, can't check for the exact model).
But that's an interesting point... Anybody else here has a Wireless NIC?

hi, i am following this thread almost from the beginning because i had the same problem of all of you, and obviously noone of these "temporary solutions" worked on me...

but now that i fixed the problem i registered to the forum cause maybe it can be useful for other ppl too: it's not a realtek fault, but a svga driver one, nvidia in my case.
I saw that the audio problem comes when the svga clock changes due to the nvidia Power Mizer function.
You can disable this function with some utilities like
Powermizer Switch.rar - File Shared from Box.net - Free Online File Storage
and reboot...all worked here, hope you can fix too

Win 7 (Build 7600) EVGA 750i FTW

Wow, I can't believe that i'm not alone on this issue. It is the one and only thing that is "at this moment" bugging me. I never had an issue with Win 7 RC, but now when i use iTunes or Media player i get a random loud buzz, and sometimes the volume lowers or audio stops coming out of the left speakers. iTunes is much worse than Win Media player. Hope we can get a fix for this soon.

@Palaz

@Palaz, I do not have an Nvidia card, I have an ATI Radeon. my built-in nvidia card is disabled automatically when a card is inserted into the PCI-E slot.

the equivalent ati feature of nvidia PowerMizer is called PowerPlay, but it's harder to disable

a user will try to disable ati PowerPlay function, if it will work for him probably will work even for you

Hello everyone. This is my post in sevenforums.com.

This issue has been driving me mad ever since I tried the beta (build 7100) in my asus laptop. Now I have installed Windows 7 pro x64 (build 7600 RTM) and I still experience this annoying crackling with my realtek hd audio ALC663 codec.

I have tried several versions of the realtek drivers with no sucess. So far, I only know three ways to get rid of crackling and popping all together:

1- use realtek vista drivers <1.81.
2- use WASAPI output in foobar2000.
3- set the bit/sample rate to 16/24 bit 44100 hz and disable all audio effects.

Unfortunately,enabling any dsp (equalizer, echo,dolby expander/natural bass) brings back the popping/crackling. Also, I don't think this is a graphic card issue, since disabling Nvidia Powermizer issue does not get rid of the problem.

I have tried everything (using HDMI output, bios updates, newer drivers) but the crackling is still there.

Can you change your power settings to "Performance" and report back?

son gohan · Nov 6, 2009

I changed my power plan to "High perfomance" , but crackling still persists with the latest drivers (2.36)

This must be a driver issue, since the 1.81 releases works just fine, even with DSP effects enabled. Still, I miss dolby headphone & bass enhancement support from the newer ones :-(

SOLUTION

I GOT IT

Let Windows 7 install its recommended driver

OR

Download the new driver from realtek

Now go to te sounds option under control panel

Select the speakers and click on properties

then go to levels
and reduce all levels to 50 %

install your latest k-lite codecs etc and your problem is sorted

recommended to recude mic volume and mute it and lin in volume and mute it/

cheers all

son gohan · Nov 8, 2009

that didn't work for me. I still experience crackling at sampling rates other than 44100 hz or when I enable audio enhacements. Perhaps it's the shared mode resampling engine the one that causes so much trouble.

DigitalDeviant · Nov 8, 2009

I had to sign up and share my frustration. None of the fixes I've tried here have worked. One odd thing I've noticed though is that AC3 over s/pdif works fine. LPCM over the same s/pdif does not. I used ffdshow to the same source file and re-encoded the audio on the fly with ffdshow to 640kbps AC3 and it played fine but pops quite noticeably when decoded and sent to my receiver as LPCM.

Hopefully this will get fixed soon enough. I can plug my old Siig audio card in but was hoping to use the 192KHz on-board audio until I can afford a HT|Omega.

Heya i don't know if anyone has suggested this..
but i played around with sound manager and found a fix.. (not all static is gone but most is)

1. Go to sound in control panel
2. click properties on the speakers your using
3. click the dolby tab, untick "natrual bass" - less static
4. now click the advanced tab, click the drop down arrow and reduce bit rate to lowest (16 bit, 44100hz CD Quality)

NOTE this doesn't completely eliminate the static, but it gets rid of most of it.

Hope this helped..

Sickpuppy22 · Nov 13, 2009

Alright so after a days or so Googling a fix trying almost everything, i came upon a fix so Stupid yet ever more practical.

There's currently a problem with SB cards/nforce chipset/ and 4 gb of ram causing the snap/crackle/pop some people have it some people don't, for those who do try this as it worked for me!

Click start> Accessories>Run.... type msconfig

Select Boot tab>click advanced and set maximum memory to 3990mb.

Reboot and have fun.

I have this problem too, tried all the methods and they didn't work

I'm on high performance, disabled all sound effects, running on 16-bit 44100 hz, disabled powerplay, etc.

What I can verify is that the problem completely goes away in older versions of the driver, but I have reason to believe that I NEED a newer driver because it fixes a bsod that I'm having.

What is also strange is that I have the same sound card and OS on my desktop computer and the sound is perfectly fine without having to tweak any settings. This means no disabled all sound effects, and when I tried to look for powerplay in CCC, it wasn't there (the card is HD3850, so it does support powerplay).

Finally, my laptop originally came with Vista and the sound was perfectly fine there too. Only until upgrading to 7 do the problems start with the latest drivers

i still have the sound problem..
actually mine is not so serious, just some short (0.5 seconds) Crackle/popping happen randomly..not only while playing music in WMP..but also watching youtube video, system sound .etc..

after install and uninstall the Realtek driver (Audio and also NIC just in case it got conflict).. also reinstalled Windows 7 few times (tried x86 and x64..both got same problem).. still no perfect fixes for me..

the best driver for me now is R2.22 (which is the latest realtek HD Audio driver for Vista).. i found out 1 thg.. the driver is dx10.. now i'm thinking that dx11 is the cause of my problem.. realtek driver not really support dx11 completely i guess..

looking forward for future release.. hopefully can fix it..

Used this solution as a temporary fix. I do believe the DX10 theory sounds like the most probable reason. Maybe there is some way to force the newest drivers (2.36, etc.) to render in DX10, just like you can with games?

I already tried that. In fact, you supress all the crackling by disabling all sound effects + dolby.

AS this issue is still not fixed, I have contacted realtek Taiwan PC support . They have asked me to dump my audio device data using their internal realtek dump utility. If you can, email [email protected] and tell them about this issue. The more device dumps they get, the more information they'll have for fixing the problem.

collegebored · Nov 14, 2009

this may be obvious, but it seems the problem really shows up when mixing sounds. with newest drivers i have minor crackling when playing music in itunes. as i add sound sources (eg, games, youtube, IM/windows sounds) the problem becomes exponentially worse.
with the older drivers (2.22), i have no problem with a single audio source at all, itunes plays clearly, but again, as i start a game or recieve an IM the sound crackles.
just my 2c.

ps: im on windows 7 ultimate, 32bit.

cecirdr · Nov 15, 2009

I think this worked

I think this worked! It may be too soon to tell, but I'm playing my music just fine right now and for the first time....no popping. Here's hoping that it stays gone.

tbuck said:
Before anyone tries to blame hardware, my same hardware config worked fine under Vista Home Premium x86.

I notice the popping and clicking THE MOST when I turn on iTunes visualization but it happens when iTunes is not even open, like playing through Napster (flash player). The default MS drivers were crackling like hell, I put up for it for weeks and finally did something about it today.

I just downloaded the 2.33 driver from Realtek today, it helped but did not improve.

Someone mentioned an obscure setting further up in this thread so I went poking around in the Control Panel > Sound area.

Under Control Panel > Sound > Playback Devices > Properties on Speakers > Enhancements:

I tried checking "Disable all sound effects", this seemed to help but not fully resolve the pops and clicks.

Next, in the same place I checked "Immediate mode" and it seems to have cleared up all the popping... does this help anyone else? So far so good, I just hope it doesn't come back again, like has happened to everyone else... :sarc:

I am still using the 2.33 driver.

son gohan · Nov 16, 2009

Realtek PC support has confirmed that the crackling issue is caused by the SiS 671DX+968. chipset present in my laptop. According to them, their drivers are generic, but they cannot guarantee that they work on all systems. Still, they have suggested that I should download a newer beta release (5898), which unfortunately will take a lot of time at 4 KB/s :cry:

.

I'll report my results as soon as I have them installed in my system.

JoHn87 · Nov 16, 2009

guys, i haven't read all post.

but what came to mind when i saw words: crackle and realtek.

I had this problem before, that annoying crackling noise.

Fix by low the PC beep volume to 0. (see screenshot below) or just mute it.

for some reason it doesn't crackling anymore.

I know the pc needs the beeping noise when booting up, but it could be the bug realtek is working on.

I hope this fix your crackling problems.
