The VideoLAN Forums

Hi I have had the latest version of VLC for a couple months now, and it seemed to be running just fine until a week or two ago. Whenever I try to play movies (mostly .ogm and .avi types, I havent tested others) the sound is extremely staticy and ruffled. I know its not a problem with the movie file, because i tried playing back some older ones that used to work fine and now they sound horrible. If anyone knows how I can fix this, it would be greatly appreciated. Ive tried reinstalling the program but that doesnt seem to have had any sucess.

Even I have been experiencing the same problem. The files are playing in other players but not in VLC. I am using Windows XP with service pack 2. I uninstalled and tried using the previous version, but the problem persisted. Actually I am missing Vlc . Hope this gets rectified early.

I was also experiencing this problem, but remembered it was shortly after windows update had update my nvidia onboard sound card audio codecs.

Don't upgrade this in Windows Update.

Nvidia Corporation - Sound - NVIDIA(R) nForce(TM) Audio Codec Interface
Download size: 0 KB, 0 minutes
NVIDIA Corporation multimedia software update released on October 22 2004.

It is listed as a high priority update, but totally mucks up sound playback on vlc.

Find your NVIDIA(R) nForce(TM) Audio Codec Interface in your Device Manager, and go to it's properties, the driver tab, and roll back the driver.

This should solve your problems.

Hope the VLC developers can have a look at this problem.

I developed the problem yesterday and I'm so glad the fix was simple.

Thanks for the solution!

I had the same problem. Thanks for the simple fix.

I somehow KNEW it had something to do with bleeding Microsoft!

I distinctly remembered there was an update, those sneaky *%#&@^%!

thanks i saw that audio codec download and should have known better

Thanks for the tip! Worked like a charm!

No problem guys, glad this helped so many people - any vlc developers looked into this issue yet?

Steve

GREAT!
Thanx stevepd!!!

Hey, i just started getting this problem and when i went to fix it. it said "No driver files have been backed up for this device" what can i do?

Hi guys,

Imho this topic should be a sticky because lots of people are going to run into this one. I am so happy that my VLC player is working once again as it appeared to stop completely at random!

What a fantastic support forum, for such a fantastic player. Death to micro$haft. Hehe.

Cheers again,

Porky

um sorry
but how do u role back drivers
i tried right cliking but it didnt say anything about that
sorry for the inconvience

Microsoft SUCKS!!!!!!!!

I downloaded Videolan today and also experience sound problems. Better said: the sound is horrible/terrible! I have no problem with the sound using other players.
I'm using Windows 98SE, the soundcard is a C-Media CMI8738/C3DX PCI Audio Device. As all other software functions alright, it must be a Videolan problem... What to do?

Thanks for the easy fix. Now the sound is working finein VLC. For the person who asked how to roll back drivers, I'll tell you what I did in windows xp:
Start
Control Panel
Sounds, Speech & Audio Devices
Sounds & Audio Devices
Hardware
Highlighted NVidia
Properties
Driver
Roll Back Driver

I am also having sound problems with vlc ... I've been using vlc for a few months, and everyting worked fine until about a week ago, when the sound suddenly turned into a horrible screeching noise. I tried reinstalling the drivers, to no effect, setting audio output to win32 waveout, which caused my system to crash, and finally reinstalling DirectX 9.0c, which solved the problem ... apparently. Then yesterday the sound became horrible again, and this time reinstalling DirectX didn't change anything. Any ideas ?
For information, I'm using Win98 SE and an onboard C-media AC97 sound device ... And I don't have any sound problems with other software.

Looks like I had a stroke of genius right after my post . I opened dxdiag and disabled the hardware acceleration in the sound properties window. That solved the problem again ... For now, at least. The sound is a bit tinny though, but still audible.

thanks a lot!

...works like a charm!

TY stevepd. No thanks to Microsoft.

John van Hulst and grumbling guest seem to have the same problems... Here, even CD-Audio (via IDE) is corrupted.

Fresh insatll of Win98 SE, drivers from mobo-CD, latest IE and DirectX 9.0c (both from CD, made from 'genuine Microsoft' downloads). Windows Update (only the important ones). VLC 0.8.1

Asrock K7S41GX (SiS onboard VGA w/shared memory, C-Media sound on board).

I will try disabling hw-acceleration, but this may not be the ultima ratio... The machine is to be used for amateur radio (SSTV, PSK31...).

Oh... It works fine with Linux (Knoppix, kernel 2.6.11; xine 0.99.3).

hi,

i have gone thru all above solutions but unfortunately all in vain...

i have windows 2000 and i recently installed Direct X from microsoft as my video display was giving problem... now my display is coming fine but audio is awful, even for files which were playing fine earlier. audio is like jamming or strucking.

i tried making acceleration zero in direct X sound properties and reinstalling vlc....but nothing is working out...

can somebody really help with that...i wanna give up my windows media player and codec packs which i m forced to use in absence of vlc......

thank you sooo much, couldnt figure out the problem myself untill i read this thread. gonna go back and watch some naruto now. thanks again!

ok the driver is digitally signed by microsoft and provided by nvidia. do i still need to roll it back?
