VLC Player Audio not working

[princeandme2]

The sound on my VLC Player Audio won't work. The audio preferences are normal, so I don't know what is wrong. Any help?

[Jean-Baptiste Kempf]

Change audio output module.

[mannieg]

I am using Windows7 32bit. I have tried every output module available. It makes no difference. I get no sound out of VLC. When I use some other program (e.g. Irfanview) I get audio. If anyone else has experienced this problem and can suggest a fix, it would be greatly appreciated.

[VLC_help]

Open Tools -> Messages... (set Verbosity to 2) and then start playback and report messages here or use pastebin.

Strange, there should more supported channel modes.

[princeandme2]

I've changed the audio output already, but it still doesn't work. I've also tried other players but the sound still won't work, and I even downloaded their sound upgrades and everything.

[VLC_help]

Sound doesn't work in other players?

[princeandme2]

I've downloaded a few other players, but only some videos work for some players and others don't. Only a few have sound, but the non-english ones have no subtitles.

[VLC_help]

Did the sound work earlier with VLC?

[princeandme2]

The sound used to work perfectly fine but then one day it just stopped working. I didn't do anything to it and I'm using the same videos that worked on it before. I tried redownloading it and updating it but still no sound.

[Datakinder]

I had the same problem with Windows 7 Ultimate 64bit. Suddenly one day the sound in some applications stopped working, probably due to an update in Windows.
I poked around in the system settings and eventually found out that the primary sound output had changed from my soundcard's speaker output (ESI Juli@) to the headphone jack. Right click the Windows speaker icon in the notification area, choose "Playback Devices". You'll be given a list from where you can choose the default output device for your sound an set as default. Choosing the speaker output for my soundcard worked for me. Make sure that you've set the output device in VLC to default.

[VLC_help]

If the problem is VLC only in Vista or 7, you can try registry tweak

[princeandme2]

Thanks for your help. I finally got it to work again.

[letsgethigh007]

How did you fix the problem? I am having the same issue...

[bob_420]

letsgethigh007...if you still haven't fixed your vlc issue, what I did to fix mine was do a search on your computer for vlc when all the files come up, there should be a shortcut found called reset vlc media player settings and cache files. double click it. if your computer is good, and fast you may not be able to see anything happen...but, when you open a movie it should now play the sound. I swear I never changed anything in my vlc settings, but after trying this, mine works fine, and plays my audio again. Hope this helps you... Bob

Deactivate GPU decoding.

[ginger_nge]

My audio has just stopped working for vlc, even though it's previously worked with the same files. I've re-downloaded vlc, changed the audio devices. I'm not following the responses above on how to fix it. I'm totally unsure about what to do. Also, I'm using windows 7.

[rocky]

For WinXP: Change to waveout and close VLC, then restart.

[Heletia]

I HAVE THE SAME PROBLEM!!

I have Windows 7. This just happenend all of a sudden a couple of weeks ago. The sound started cutting in and out on 'ALL' video playback devices on my PC. Looked up google and reinstalled the Realtech Audio driver but still did it. Was told I might have to reinstall windows all over again. Did some more tweaking and the audio seems to be playing steadily now except....

*** Now I have NO AUDIO on playbacks I've recorded from ***.AVI*** files.
recorded from an mp4 and wmv and they playback fine.

This is URGENT for me as I use recordings for my Official Celebtrity Sites.

I have it set to FIX avi's which it does.

I've done everything everyone has suggested already and nothing has helped.

- I have no microphone.
- All settings look fine in PC Audio.
- Reinstalled HDTV Dvico Tuner Card.
- Pulled out all the cables and put them back in again.
- Have reset VLC player again.

*Could not find where to 'Deactivate GPU'. Looked in: Tools -> Preferences and Input & Codecs but wasn't there so changed it to " Auto" instead.

Please help, i don't know what to do and am getting stressed and behind on all my work.

Many thanks
Helen

[Heletia]

Been reading more... was suggested that as avi files can all be coded differently, I download:
K-Lite Codec Pack 11.05 (Full)

If that doesnt work all I can think of is to convert the file to mpeg or mk4 (dont want quality reduced) . but i cant do this for every file from now on!
