Hello,
Lately I'm experiencing problems when playing music both on my office PC and on my home. My office PC is x64 bit while my home PC is x86. What they have in common is an NVidia card (7300 on my home PC while 9600 on my Office PC) and MoBo integrated Realtek Sound Chip. The systems are up-to-date, drivers are updates via Automatic Updates. When I experience choppy sound, I reboot the comptuer(s) and sound will be okay for a few hours. I have no idea what can trigger to be the sound slightly choppy again. Sound is both when playing movies using Windows Media Center (on my home PC cause I don't watch movies at work lol :D), when listening to music using media player or Winamp. Even when I don't touch the PC so there is not much animation on the screen. If I disable enhancements in the Sound Control Panel Applet, the sound is not so choppy but won't fix this problem completely.
Software what both computers have in common:
Any suggestions to further diagnose the problem? It's kindda annoying.
Thanks,
Levi
For those who have this problem and want to see if this solves it for you too:Click your start orb, type "services", press enter, find and restart the "Microsoft Antimalware Service". Turn real-time protection back on if it's still off and was on before. Check your sound, and it should be fixed!
Vincent,
Thank you very much for the suggestions! Finally some helpful guidance!
I used DCP Latency Checker and was receiving peaks of 27,000 when it started to get choppy, 50,000 when it was pretty choppy, and really bad it was peaking at about 75,000-80,000.
When not skipping and everything sounds great, like after a reboot, the peak doesn't even go above 500 (if so, rarely, and hardly any higher).
I know hardware resources wasn't my limitation, as I'm running 8 logical 3ghz cores and have 6GB of high speed triple channel memory with at least 50% available most of the time. When bad audio drop outs were occurring, I confirmed this (0-3% cpu usage and 3+ GB of physical memory available, even with my page file disabled to increase performance).
While the DCP Latency Checker was all in the red (high values), I started going through my running services and restarting, one by one. Then I got to "Base Filtering Engine", which has a description of: "The Base Filtering Engine (BFE) is a service that manages firewall and Internet Protocol security (IPsec) policies and implements user mode filtering. Stopping or disabling the BFE service will significantly reduce the security of the system. It will also result in unpredictable behavior in IPsec management and firewall applications." I proceeded to try to restart it, which popped up a message saying 3 other services would also need to restart in order to restart it: IPsec Policy Agent, Windows Firewall, and Microsoft Malware Protection Network Driver. I clicked "yes" to restart all of them, and after a few seconds windows tells me "Windows could not stop the Base Filtering Engine service on Local Computer. Error 1051: A stop control has been sent to a service that other running services are dependent on." So I click Ok, and I look in the DCP checker program, and my latencies are all still red and reading way too high. At this point, windows firewall is disabled, all other 3 services are running though. So I try to restart it again, and it succeeds. Instantly, my DCP checker levels are back in the green and low numbers (<500) and all audio skipping has stopped. I'm still not sure which service it is, since it could be any of these 3:
1. Base Filtering Engine
2. IPsec Policy Agent
3. Microsoft Malware Protection Network Driver
Update: Now that my sound was off again I got to do more debugging, but I don't even see the third one listed anywhere in services, neither on nor off, but restarting IPsec Policy Agent did nothing. I restarted Microsoft Antimalware Service since it was the only one that sounded related to #3 above, and that did the trick, DCP levels dropped instantly and no more dropouts. I'm still doing the same thing every other day or so, or sometimes once a day (depending on how much I use my audio...? possibly?)
So, does it make sense that this service would be causing problems? This means it isn't a driver issue--correct? If it's not a Realtek driver issue then it's microsoft's issue and needs to be fixed--it's their service and software that seem to be causing the issue/conflicting with the driver. I guess it could be either one's problem, but both realtek and microsoft can fix it if they want to! It would be nice to not have to do this almost every day just to use the sound
Thanks again Vincent!
Dear Azeez,
Yes, It seems that on my hone PC sound is going to be choppy after my computer resumes from sleep. (Although, I am not able to reproduce this issue when I want to - even if I give out the sleep command 5 times, the sound won't be choppy, only sometimes when Mr. Computer wants to, but usually each night I sleep the computer, not shutdown)
Regards,
Levi
levidos,
Did you ever resolve this issue? It's driving me insane!
I too have an nVidia card (EVGA 9800gtx) and suspected the graphics drivers. This issue only started after installing windows 7 ultimate (built 7600)--the issue did NOT occur when using the same exact hardware and driver versions (for both realtek's HD audio and the graphics card) on windows 7 RC1. Right after upgrading the operating system, this issue started--so I do not believe it's anything to do with third party applications (in fact, the only common applications we have installed are WMP, VLC, uTorrent, and Office2007).
Graphics driver wise, neither eVGA's newest (v197.13) nor the older one I used with Win 7 RC1 (v186.18) resolve this extremely irritating issue.
Currently I have to log off (not reboot) and log back on every couple of hours to "reset" the sound and remove all the choppyness, which absolutely increases in frequency and intensity the longer the system goes without a log off/on or restart. I've tried manually restarting the realtek and audio related services manually, but that doesn't work either.
Anyone else have any suggestions?
Hi,
Disable all enhancements and check if the issue persists.
1. Click Start, type Sound.
2. Click Sound . The Sound Window appears.
3. Click Speakers/Headphones and then Properties.
The properties window appears.
4. Click the Enhancements Tab.
5. Click to check the Disable all enhancements checkbox.
6. Click Apply and then OK.
The properties window closes.
7) Click Apply and then OK. The sound window closes.

Unfortunately, none of the above fixes this problem. I've heard from more friends who still have the issue as well.
I'm using drivers released after the previous post (7/9) that are actually dated 7/6/2010, "Realtek High Definition Audio" driver version 6.0.1.6151
After uninstalling the old and installing the new drivers (downloaded from the Realtek website as Vista_Win7_R250_x64.zip), the same problem exists: after a handful of hours of use, choppyness and static blips start getting more frequent until you log off or reboot.
This problem has existed far too long to still be a major issue and limitation of Windows 7 with the most common audio hardware on the market.
Please, DO something about it.
Most of the time this problems are related to driver issues.
However, a crappy driver most of the time causes problems from the start.
In this case the problems arise after a couple of hours.
A couple of things you can try
1 – remove third party drivers
· System: Make a restore point so you can rollback
· Device manager: deinstall the driver (write down type, etc just in case you need to download them from the manufacturers website)
· Programs - remove the audio driver otherwise it will be installed again at the next step
· Reboot and Vista/Win installs the MS High Def Audio Device.
If this cures the problem it is more likely related to a third party driver.
2 Monitoring
Use the task manager of better the Resource monitor
Watch for any program hogging memory, high CPU, excessive disk or network I/O
Sometimes anti virus can cause this type of problems.
Another usefull tool is DCP Latency checker, run it at start-up and at the moment the problems occur.
Succes

Microsoft,
Please respond to the latest post in this thread. Every one I know who uses Windows 7 with Realtek hardware has this exact same problem. Realtek is one of the biggest onboard sound card companies out there--seriously, this needs some attention. Why is your antimalware service interfering?
