This is an ongoing problem with AVAST- doesn't matter which version I've updated to but has only happened since 2014. Haven't changed anything else on the system (WIN764) so I can pinpoint it to the antivirus.
Has anyone else come up with a solution? I know it happens when Avast is just running as normal- no directed scan is taking place.
It's driving me nuts, can't play any video/audio without stammering and blurring. Even happens with online streaming!!!
Is there any way something can be disabled within the program to stop this?
Can I contact AVAST via an email to report the problem/seek a solution? :-\

In the Performance settings on your sound card, check if Hardware Acceleration and Sample Rate Conversion Quality (or something similar) is enabled.
-
And you are using Internet Security or Free or... ? My experience is that the firewall in AIS can cause this (due to high DPC latencies).

I'm using the normal paid for Avast...is that the internet security version? I do believe there's a lot of truth in what you've said as the problem only really started with the use of AVAST. Other previous AV software have never caused this problem...and there's me thinking I was on to a good deal by buying the 2 year renewal package!
Any other hints/tips to try and I'll gladly give people's recommendations a go...

I'm having this issue too, since I upgraded from free to Premier.
Audio streams from the internet frequently stutter and contain other artifacts. Local files and ones from my NAS less so, but still drastically downgraded.
I'm an audio geek, so it's extremely irritating.
All the above is the same via onboard soundcard and USB Dragonfly. Sound used to be exceptional. Now it's unlistenable.
I'm not sure if this is applicable to video files since I hardly ever view them this way.
Things are worse when I open/refresh a web page or even hover over a button. Playing files direct is also disrupted when using file explorer.
So Win7/PC - Chrome/Firefox - Avast! Premier.
Please advise.

hi,
I also frequently have this issue with audio on my pc
I believe it is caused by the cpu or ram bugs reported in avast
-
Okay, so does that mean they're going to fix it?
Is there a setting I can adjust or turn off?

See my post http://forum.avast.com/index.php?topic=141407.0 (http://forum.avast.com/index.php?topic=141407.0) on how to remove the firewall. In my case this was the only sollution, disabling alone was not enough.

I'll certainly give this a try if the problem persists any further. Is there any disadvantage to using Windows firewall over AVAST? Wouldn't the AVAST one be more up-to-date- would presume as it's a paid for service... ???
-
To be honest, there probably is little difference between the two in terms of effectiveness. The adding of (outbound) rules might be easier in 3rd party firewalls that have a more user friendly interface.

I had a similar with assemblies in AIS 9.0.2008 and AIS 9.0.2011.263. After that I deleted 9.0 and returned to 8.0. Everything works fine again, including Music, Web Surfing, Firewall and so on. The truth had not put 8.0 from the official site, and search on the Internet, as updated from 8.0 to 9.0 and did backup. Now unsuccessfully asking employees to put avast officially distribution AIS 8.0.
-
There seemed to be an update a day or so ago which seems - so far - to have addressed the issues I raised.
Let's hope!
:)

Yes, I'll agree too! I've actually manage to get through a Stone Roses live boot from 1985 and the Man City match without a single stutter...makes me sound like an obsessive Manc, honest I'm not ;D
-
Unfortunately, it's back :(
<later addition> I rebooted my computer and all seem good again. Is there some sort of buffer/register which fills up/gets too large and affects Avast!'s performance. When I used Avast! Free the computer was left on for months with no problems. Currently, I have audio issues after a couple of days without a reboot.

If you are referring to audio/video being streamed, have you tried the latest Webshield beta patch - see link in Lukor's post at http://forum.avast.com/index.php?topic=143211.msg1046988#msg1046988

It's the firewall, somehow it causes high DPC latency. This effect indeed worsens over time, after multiple hours (Days) of system uptime without a reboot something seems to accumulate/clog up.
-
Okay ... so is there going to be a fix for this?
Frankly, Avast! has ruined my audiophile playback.
Do I need to get rid of it and go for another anti-virus?

Try the new beta http://forum.avast.com/index.php?topic=144768.0
-
So far, so good, but it usually only becomes apparent after a few days ...
-
This is bull, I paid for firewall, if it gives me a problem then it needs to be fixed or a refund is in order. I have same issues if I play any game and listen to soundcloud/youtube. If this isnt fixed, then I want my money back.

So have you installed the new beta ???
-
Is this in the change log of the newest beta? If so then I'll give it a shot.
What was fixed:
Uninstalling avast might hang at "stopping service: avast! antivirus"
Performance and stabilization fixes in Stream Filter - e.g blocking of ajax calls
Several firewall fixes - e.g. blocking of google earth
Stability improvements - several crashes fixed
Let's see if it fixes the issue...

I've been having problems playing YouTube, or just about any other, videos. They will start (usually), play for a while, then stop and often the video window turns green. Turning off Avast! (I'm using the free version) seems to make the problem go away.
This is with up-to-date 64-bit Windows 7 Professional.
-
Okay ... updated ... still there.
I will be removing Avast! Premier.
This is very disappointing.

Same issue with Beta, still issues. Going to request refund if the next beta doesn't fix the issue.

No more betas, the stable has been released http://forum.avast.com/index.php?topic=145192.0
-
No issues with video/ music/ YouTube here.
and there is a new program release > http://forum.avast.com/index.php?topic=145192.0

Installed 2014.9.0.2013.
It takes three or four days for the symptoms to show ... let's see what happens.
-
Unfortunately, it's back :( Particularly noticeable when loading a new web page.
Clean install, latest version.

This is a long-going problem, there other threads about this as well. With all due respect, despite the announced changes in the firewall, I think it's ultimately flawed and probably there should be changes in the team developing it rather than to patch something obviously originally flawed. Avast bought Outpost firewall technology and then it doesn't use it. Anyway I think the firewall is the Achilles' heel of the product

Hello everyone,
I have the same issue with dpc latency lags and sound drops..
Main problem with high dpc latency of "ndis.sys".
My AIS: 2014.9.0.2013
Windows 7 x64.
_
So, anybody know any solution for this?
Here is answer from Avast support:
Hello,
Thank you for your report and information. We are not able to simulate this issue so we will monitor the situation if there will be another the same or similar report from our customer base.
Best regards,

Is it appear after ~1 day of work pc...
After uninstalling ais all going well even after 1 week of work pc...
I have no idea, how to fix it... :-\
-
Yes, it starts a day or so after a reboot.
So I'm currently running another free product while my unsatisfactory premium Avast! product awaits a cure.
Unfortunately, this has been a costly mistake for me.
-
Eh... Same to me.
I was bought this Avast Internet Security for 3 PC for 3 years.
I hope, they will solve this problem, cause I can't use my sound card. :'(
But on my other PC all is fine :-\
Btw, may be for someone will be useful this instruction (useless for me):
Note: please be sure you run all uninstall and cleanup utility as administrator and - which is very important! - you rune it AS ADMINISTRATOR. Be an administrator and run something "as administrator" is not the same so you should do right click on a exe file and choose "Run as Administrator"option.
1. uninstall avast8 (and 2014 if you have it) - you should use our removal utility
( http://files.avast.com/iavs9x/avastclear.exe )
2. restart and delete manually both avast folders. One in Program Files and one in Program Data.
Then check if in the adapter properties in control panels -> network adapter settings is not present "avast firewall NDIS filter miniport". If yes, remove it manually please.
Then go to Windows\System32\DriverStore folder and search for aswndis*.* . If there will be anything with this delete it manually.
3. Turn off Windows firewall and use Microsoft clean up network driver utility:
http://vpn.hpintelco.net/ifcleanup.x86.exe
http://vpn.hpintelco.net/ifcleanup.x64.exe
4. then clear all off-line content and cookies from your web browser and download our latest release
http://www.avast.com/download-software
and install it. Before operating system restart go to avast GUI -> additional protection -> and experts setting of avast safezone and reset Safe Zone and you may reset Sand box too.
After successful installation could you double click on you license file to register your copy of avast.
5. Turn on Windows firewall

Yeah ... did all that ... nbg

Here some pictures from me.
Red spikes (DPC lags) appear periodically or when I'm updating a page in Chrome.
-
This has been an issue on and off as far back as Avast 5. They seem to eventually fix it for about 90% of people but still it lingers. Even with latest AIS version I have issues from time to time with it spiking.
Even worse... when it causes ping to spike in online games after 20 minutes of play time. But I've noticed it even in games audio will stutter at times with shields enabled.
-
Anyone had any luck solving this?
Avast team notice this problem already! It's real.
-
Well all I can say is that I'm glad it wasn't just exclusive to me!...It did seem to rectify for a wee while, but sadly after the latest update (9.0.2013) the problem still exists.
It's so frustrating and yes, as my renewal is only about 20 days away I'll be looking elsewhere. It's a shame, I've tried nearly every premium anti-virus/internet security on the market over the last 10 or so years. Each time my efforts to find the least CPU hungry answer is dogged by other issues.
If anyone can recommend an alternative I'd be much appreciative...there are loads of free ones on download.com...
-
I'd advice using the free Avast and searching for an alternative firewall. Windows 7 or 8's built-in firewall is pretty decent, otherwise you might try Comodo personal firewall.
