Default PotPlayer audio crackling

When i watch movies in potplayer on some scenes I hear crackling in the audio. How can i get rid of this crackling? Same thing happens in media player classic which comes with k lite codec pack when i turn on the volume normalizer but in potplayer i haven't changed any setting everything is on default. And i have one more question about codec packs like klite,cccp... Are codec packs bad? because I read on videohelp and here on this website(http://www.techsupportalert.com/best...eplacement.htm) that using codec pack isnt recommended but ond codecguide forums they said following "People who say that know very little about codecs. Codec packs and the codecs themselves have evolved a lot in the past ten years. The K-Lite codec pack is very advanced and has several features for detecting, fixing, and avoiding problems. It is much easier and cleaner than installing codecs manually. Plus you can always get help here in case of any problems." so what is the truth? I use klite for example for software like subtitle workshop or subtitle edit

Welcome to the forum .

Does audio crackle when you play music on a music player too? Or, does it happen only with videos?

You can try uninstalling Media Player Classic, and the codec pack to see if it makes any difference.

You can also try changing the audio renderer in PotPlayer to see if that helps.

Codec packs were needed earlier, when media players did not come with the required codecs to play certain file types. But, nowadays with media players like VLC, PotPlayer, you won't need codecs. Therefore, if you install codecs, it's likely that they might interfere with the normal working of these players. So, it's better to go without codecs, unless you feel any specific need.

About your problem, I have provided solution based on my guesses. If George.J, editor of the Best Free Media Player looks at this thread, he might have more comprehensive, and accurate reply to make. So, please wait for his reply. You can also contact him via PM or email if you want... although he should reply in few time.

I will uninstall k lite and reinstall potplayer and see if there is a difference. You mentioned VLC but on VLC 1080 and 720p mkv are stuttering on my pc on all other players(POT, MPC-HC BS, GOM) the videos play fine. And the stuttering in vlc only happens on windows 8.1 on windows 7 everything is fine.
My pc: CPU: FX 8320
CPU Cooler: ZALMAN CNPS10X OPTIMA
MBO: ASUS M5A97 R2.0
RAM: TRANSCEND 2X4 GB 1600 MHZ (8GB)

Please do report back after you uninstall K-Lite.

About problems on VLC, I can't say much because I am not much knowledgeable about these things... but, you can try changing the video renderer in VLC, to see if that solves anything. You can do this from Preferences --> Video --> Output.

You should be able to set your media player to only use its own internal codecs and thus operate without accessing K-Lite at all. I use K-Lite (basic) to support media previews in QTTabBar and FreeCommander, while for watching videos/playing music I mostly use Pot Player/VLC/MPC-HC/Aimp3 (all non-install versions).

I've not had any problems myself with this practise although I do find that audio sometimes crackles if my CPU is topping out for any reason.

I'll be interested too to hear how it goes for you as I've heard this argument that third-party codecs are a bad idea, though I've never had issues with running them alongside other software myself. I have had issues playing high quality videos like mkv and wmv in Pot and VLC but this persists whether or not I have other codecs installed ... enabling hardware acceleration helps a lot.

Looking at your specs you appear to have a pretty powerful rig so I expect it's just a question of correct configuration which as Anupam says, George is probably best able to help you with : )

I uninstalled k lite and reinstalled Potplayer and nothing has changed. I captured the audio with pot so you can hear the crackling. Listen to the part where he says "Your boss is dead"

Here's a good article at LifeHacker that describes whether you should use code packs and the answer to all those who say that code packs haven't ruined their life.

Apart from the problems, the reason why codec packs aren't necessary is that media players have become really advanced. Take the case of PotPlayer, it's updated constantly to give you access to the latest versions of codecs and filters, while VLC & KMPlayer have proven themselves over the years. Technically PotPlayer, VLC and KMPlayer is just a media player fitted with an internal codec pack. All the points highlighted at K-Lite home and about page are already supported by PotPlayer, and even additional hardware acceleration options (Intel QuickSync and NVDIA CUDA) that K-Lite boasts about, is available in PotPlayer if you choose to install OpenCodec during installation, so I'd recommend to check to install OpenCodec during PotPlayer installation if you want more features, and also it installs/uninstalls cleanly.

As I read through various forums, many posts that I read about is users who are desperate to get their video playing properly after installing/uninstalling code packs, how they've screwed up the internal codecs, ability to generate video thumbnails etc etc. If you're not one of them you're just lucky or your time's not up yet. Microsoft themselves says that you shouldn't install 3rd party codec packs on Windows 7 and higher, because of the way they mess up with the registry.


[sorry read your specs now]


There are certain things you can do:

There's a host of audio preferences available in PotPlayer.

1. Like you reported, in MPC_HC, the problem comes when you turn on volume normalizer, you could try to disable it in PotPlayer, by right clicking on interface->Audio->Audio Processing->Uncheck Normalize

2. Try resampling the audio to a different refresh rate. Right click->Audio->Output format/Resample->Try various values that suits the video.

3. Change your audio renderer. Right click->Audio->Audio renderer.


About the stuttering problem for HD mkv videos in VLC, it's probably because of file caching parameters, and I've solved the issue in the past by going to

Tools->Preferences->In the bottom of settings window, change Show Settings to "All"->Input/Codecs from the left pane->Scroll down to Advanced->File Caching (try a higher value like 1500, 2000 or 2500)

In potplayer i unchecked normalize and it helped and in Vlc by increasing the file cache to 1000 also helped. Could you only explain why increasing the fille cache stopped the stuttering? That means that my computer is powerful enough to play hd mkv without problems right? And a few more question what player would you choose for video playback VLC or Potplayer and why? And now when i uninstalled klite which codecs should i install to have video playback in subtitle workshop or subtitle edit because with them i can synchronize subtitle with video permanently?
