VLC video player suddenly has no sound Solved/Closed

Question

Hello, 

I have been using my VLC media player to play video recordings for a project I am working on. Everything has worked great, but suddenly, while listening and watching a video file, the sound stopped playing. I thought it was a problem with the recording at first, but I went back to the part i'd just been listening to and now it has no sound either.
So it seems to be a problem with the media player. 
I did already check audio preferences and my S/PDIF box is already unchecked.
My sound on my keyboard is turned all the way up, and the audio isn't muted (at least no check by the "muted" on the audio menu.
I hope someone knows what to do. I'm bewildered!!! Hope someone can help. Thanks in advance!
The files are MTS files but I doubt that that matters. I've always been able to hear the sound on these files before.

Configuration: Mac OS X Snow Leopard (10.6) / Firefox 18.0

Also, I did try closing the program and opening it again.

Thank Paulger, for your suggestion. I'll do that!
I also just found that doing the opposite of what was recommended on another site actually fixed the problem for me. I CHECKED the box (in VLC Preferences . Audio) that says "Use S/PDIF when available"
Several people advised to UNCHECK that box. But mine was already unchecked so I just experimented to see if checking it would help and it did. That turned the sound back on for me.
Thanks again!

See also the article : "Video Overlay settings at zero after changing scheme" from intel

     This solved my problem. It was odd because I had audio but no video in ALL video players. It took me quite some time to figure mine out. And IT wasn't even a codec problem or anything wrong with the various players I tried to use.

Obviously my computer has a intel graphics driver, but you may have a similar problem. Worth a shot. I was switching schemes as I was using a HD TV as a second screen on extended settings and then switching back all the time of late.

I had the same problem. I tried everything, changing audio-codecs, reinstalling drivers, reinstalling VLC player, rebooting system to earlier specs. NOTHING worked... then I tried simply deaktivating the soundtrack inside vlc player and then activating it again, and boom, problem solved... just wish I have'nt used 2 hours when the solution was so simple.

I hope this helps some of you.

experienced this as well and spent around two hours tinkering with all the options, it was finally solved after I muted then un-muted the audio. What a waste of two hours that was =))

Just go into settings and click on 'reset preferences' down the bottom, that should work.

I activated, deactivated and activated the S/PDIF box and still can't get any sound. The mixer is fine. Files work with divx, but divx is crap since it doesn't launch movies by dbl clicking movie icons but instead opens up a divx browser from which you then need to find appropriate movie files. Vlc sound stopped woyking when some windows updates automatically uploaded. Worse than a virus!

Start playing a file on VLC.
Open Windows Mixer.
Scroll 'til you see the VLC icon.
Turn the volume up.
It's what I just did and it worked for me.

I tried all the suggestions in here, other than the Intel, which doesn't apply, and it seems my solution was just as simple.

I opened the control panel, clicked on the Sound option, and Windows said "Enhancements for this audio device are causing problems - Disable" - clicked yes for both devices and everything now works fine.

I ran into this problem while teaching my students.  In between classes I worked on editing a movie and plugged my headphones in.  When class started back up, I unplugged the headphones and went back to my speakers.  No sound.  I tried all of these options above one at a time, painstakingly making sure I followed every step correctly.  Nothing.  I restarted the computer.  No sound.  

After much aggravation, I decided to open up the movie I created to watch it.  I had sound again.  I closed the movie down, opened up my music files, and resumed business as usual.

click on Speaker icon, then click on Mixer, you will see volume mixer options, that is where you can check if the sound is muted.
