Windows 7: does anyone actually have the Sound Stuttering fix?

21 Jun 2010   #31

Windows 7 Ultimate x64

I just want to say big ups to Jag for his post. The program DPC Latency Checker allowed me to determine that my wireless card (TRENDnet TEW-623PI) was causing audio and video stuttering for me. I simply downloaded the latest drivers from TRENDnet's website, and voila, problem solved (I would have otherwise just disabled it).

Thanks again Jag, that program helped me in fixing this annoying issue.

Windows 7 Enterprise
I went to sleep after installing vpn softwareS - day after, BAD sound

Just posting for my own future reference...

Stuttering sounds, sound that sounds metallic / crippled / digital error-like; combined with high cpu usages to 100%.

Running Windows 7 Enterprise x86.

Not only I installed some VPN tools; also my NVIDIA display driver was updated by Microsoft Update (which failed) and then by me (which succeeded). This could also have something to do with MY specific problem...

One interesting thing to try is removing all network adapters. This might reduce cpu usage.

This improved my situation, but it was not the root cause. After calming my pc down there were still stutters and crackles in the sound.

The latest version Vista_Win7_R251_x86.exe made the problems even worse.

So I tried this driver (after removing the device in device manager, and not re-installing it, I ran setup). After reboot all still seemed bad (tested with youtube in Firefox). So I started Chrome and made some food; while I was preparing my food, I suddenly was greeted by a clear sound from youtube (autoplay).

What happened? I dunno, but this version brings my sounds back to the old state... (from: Realtek HD Audio Driver - download tag - Softpedia).

The driver is made for Vista, not Windows 7, and that is why it installs & works perfectly ; P

More information - problem not solved - I'll check PCI-E laters...

Sigh. Me bad. Problem not solved : (

I can add this...

Changing the quality settings for sound to the highest dvd Hz level, reduces the echo-like loud digital noise interruptions, crackling, artefacting and whatever : ) But does not solve it. Neither do the other options seem to matter much.

Also I noticed that going full-screen makes the sound quality poorer with more and louder artifacts. Also, the sound artifacts almost completely disappear when my web-video is hidden behind another screen or playing in a not-selected tab.

This is also the moment that my CPU becomes quiet again. So... I'll repost with more info, but for now my guess goes to the newly installed NVIDIA driver... The bad sound quality then would be caused by high cpu interrupts which prevent smooth video playback. BUT, DPC Latency check (I did not know this program), shows nothing particular. Maybe a yellow spike as an exception, but that's it. Normally all is in the green - also when playing full-screen.

8400 GS not to blaim

removed the video-driver, restarted with VGA mode (for there is no more video-driver: ) and still the sound was bad. Feeling stupid, but almost feels like I have to install a fresh Windows all together : (

Audio stuttering problem solved for me

Hi Everybody,

I only registered here to offer a possible fix.

1. Download the DPC latency checker: DPC Latency Checker

This program tests your system and can tell you if you have drivers that aren't performing properly. The only problem is it doesn't tell you which one so you have to disable various drivers one at a time in Device Manager; and observe the effects. After pressing the "reset" button (after disabling a particular driver) it will take the program about 10 seconds to see if there is an issue; which is seen by red bars that indicate latency issues, in real time.

2. Run latency checker

3. Open up Device manager

4. One at a time, disable things like sound cards, network cards, modems; hit reset on the latency checker program, and watch for the dreaded red bars to appear. When they do, the software will give you a message that there is a driver on your system that isn't working right. Keep trying to disable drivers, one at a time. Eventually, you should get to the point where all you see are green bars.

For me, it turned out to be the wireless PCI card. In my device manager, it is listed as: DW15125 (802.11n) WLAN PCIe card. As soon as I killed this, no more red bars, and no more audio stuttering. Unfortunately, no updated drivers are available for this device.

I have a Dell XPS-Studio 9100, 9 GB ram, Win 7 64-bit, Intel i7 930 @ 2.8 Ghz; so everything should be super smooth with this machine. Running Apple iTunes, Windows MP through two seperate sound cards etc. All scenarios had this stuttering issue.

As a precaution, I had also unplugged my bluetooth adapter, a USB Cruiser 8gb thumbdrive, and killed my virus protection. Once I found the culprit (above) I re-enabled all of those things and still didn't have any issues.

This is a desktop and I am "hard wired" into a router with an ethernet cable. No need for wireless here - but the stuttering audio was driving me nuts. I think I tried about 25 things until I used the DPC latency checker to observe the effects on the system when I disabled each driver one at a time.

I hope this works out for others.

Win 8 Release candidate 8400

Hi and welcome

We have been recommending Latency checker for months. It does the job is free and actually works.

Indeed - I got the idea to use Latency Checker from this forum, but I didn't really find a nice explanation. My post was just to a) confirm that this is a good method to find the culprit driver b) provide a different style / description on how to use it and to provide which device on my particular system caused the problem.

I have problems too with an audio drop-out every few minutes. It sucks. When I use the latency checker, I'm green bars all the way. Ugh.

Sounds like a background process interferring. Do you have Windows Defender active, what Virus program are you using?

If you're running any kind of file sharing program with a virus scanner that's doing real-time checking you might get some dropouts.

Also, some of nVidia's background services are real hogs, might open taskmanager
(right click on task bar) and quit some of the nVidia background processes and/or check to see what nVidia services are running. You don't need most of them.

Windows Seven - Ultimate (x64)

Has anyone posted a remedy yet? Are Microsoft aware of this glitch? Also random mouse cursor - what's that all about? Just goes anywhere it wants!
Well, this is the closest I've found; a "Microsoft Moderator" commenting:
Sound skips/cracks under windows 7 32bits.

But to be honest, I don't think she's has the ability to actually deal with the issue. She left the thread as I turned out it's not a local problem

And they're curious why people don't change to Windows 7...
