solving the Audio distortion problem in VLC 0.8.2 on Windows

[Iluvatar]

Hey folks!

I run an AMD64, and for a long time, I had a hard time getting any useable sound from my VLC.
But these steps worked for me..

Preferences > Advanced [x] > Audio > Output Modules > "select Direct X from the drop-menu" > Direct X > Uncheck (Use float32 output) > Save&restart...

Hope this works for the rest of you.. took me about 5 months to get this --please stay polite-- working.

Problem Solved!

Well, I'm having the problem in Firefox.

So am I. Any update on how to solve the screeching if you installed the Firefox Plugins?

-reset all
-equalizer 10 bands @ filteropitions
-win32 waveout on "output modules" (advanced [x])
-"Output modules" ---> "DirectX"---> disable "use float32 output" (advanced[x]).

I think this mixture of settings should make some of us happy

I also disabled "use float32 output" on WeaveOut... worked great for me... thank you all... this player is quite something. Best image ever in my monitor.

If you use DirectX Output set the "Sound->Hardware Acceleration" in the dxdiag program to "minimal" or "off" - worked for me

[locotus]

Thanks, but it didn't work. I'm using MPClassic for this streams, with no problems. I'll wait for the nest release.

this worked for me

uncheck "high quality audio resampling" in the advanced audio preferences

[locotus]

Thanks, but upgrading realtek ac97 codes help with some of the wm audio problems, still some distorsions. The audio for the RTVE is still missing, and in the stream view the codecs are undef.

solution on first page worked well for me on amd 64

[brucel]

Turn up the sound settings after you change the settings... that fixes the no sound

shame on me, that was 'only' a driver problem

[jock]

Im pretty new at the whole computer thing,
im wondering how do i get sound, video is great, any ideas??
cheers

First, I lost sound as others complained, then I reset "Output Module" as default and changed "Audio Output Frequency (Hz)" as 48000 in the Advanced Options of Audio. It worked for me.

Thanks.

This solution worked like a charm for me. Thanks!

The problem exist on my motherboard with NVIDIA nForce4 chipset.
I solved the problem with new driver for the AC´97 chipset.

Originaly i had the offical nForce4 driver for the build in audio on my system, after replacing them with the new AC´97 driver from Realtek the sound bug is solved.

Driver page from realtek

*S*Y*S*T*E*M*******************

- vlc-0.8.4-win32-beta
- WinXP Prof. SP2
- AMD Athlon 64
- MSI K8N Neo4:

• NVIDIA nForce4 Ultra
  8 Channel ALC850 Onboard Audio
  (AC'97 Codec)

*******************************
Should work with vlc 0.8.2 also.

--------------------------------------------

Das Soundproblem tritt in Verbindung mit den Orginaltreibern von NVIDIA beim nForce4 Chipsatz auf. Ich habe den Bug gelöst indem ich die neuen AC´97 Treiber direkt von Realtek installiert habe.

Die Treiber gibt es hier

@timeloop

mit welchen treibern hat es dann genau geklappt ?
mit A3.76a klappte es bei mir nicht.
und die beta version lässt sich nicht downloaden! ?

habe selbst einen xp 2700 + asrock k7nf2 board + win98se.

das tonproblem in vlc lässt sich bei mir nur über das abschalten der beschleunigung durch dxdiag beheben. jedoch darf man dann nebenbei
den rechner nicht anderweitig belasten. -> das ist doch blöd.

die anderen einstellmöglichkeiten die hier im thread beschrieben wurden, die finde ich unter win98 leider nicht --> vielleicht kann mir da ja noch jemand einen tipp geben?

komisch finde nur, das alle anderen player fehlerfrei laufen... nur vlc
will eben nicht.

Most players don't use DirectX + float audio.

Most use waveout (but that doesn't support digital audio output)
And most applications output int audio.

Nvidia drivers say they support float audio, but in reality they don't
And the DirectX Hardware acceleration turns this into an incredible noise.

It IS a driver issue, and "other players just work" is not proof that the drivers are 100% ok.

[Dandruff]

maybe it would be wise to output/convert to 32bit fixed instead of float!? then you can maybe close all the audio problem threads ...

[sven31]

schön und gut. aber kann mir mal jetzt einer auf deutsch erklären,
wo und wie was einstellen muss, um vlc fehlerfrei zum laufen zu bekommen, ohne den directx beschleuniger abzuschalten!?

Audio Output Module (Choose Win32 waveOut extension output)

finde ich nirgends (in vlc)!!!


grüsse sven

[Dandruff]

steht doch alles im ersten post des threads -> erst die erweiteren einstellungen aktivieren (unten rechts) -> dann waveout als output einstellen und evtl. noch float32 deaktivieren. danach sichern und vlc schließen und neustarten.

[sven31]

@Dandruff

vielen dank. jetzt klappte es auch bei mir.
ich blödi habe die ganze zeit in 0.7 und 0.81 rumgesucht und
dabei nicht auf neu öffnende funktionen in den oberen breichen geachtet.
--> das ist für mich alles irgendwie unnötig kompliziert.

naja ich hoffe es klappt jetzt alles.
nochmals danke!!!!!!!!!!!!!!!
grüsse sven

[Dandruff]

alles klar

[obarthelemy]

i solved the problem be deactivating: "use float32-output" at directx and waveout, so i didn't have to change the output-module to win32-waveout...

but not 100% perfectly, the sound still crackles a wee bit (not a lot at all, VLC IS usable).

I read somewhere (sorry, can't remember where) that there is an issue with the PCI bus getting saturated because nvidia does not report the state of the sound queue correctly. That's greek to me (or rather, that's geek to me), but maybe you can lake something of it

[The DJ]

I make the following of it: "Nvidia makes really sucky audio drivers, and should pull out of the audio market and keep to video"
