Update 30-12-2014: added some alternative solutions in case the primary one does not work
In case your VLC Media player suddenly has no more sound, and you are running Vista or Windows 7, why don’t you check your audio mixer? You may have set it to mute at some point, and forgotten all about it. Windows will remember these settings and mute the program the next time around as well. Here’s how to get there:
- At the bottom right in the startbar near your clock, there’s a small speaker icon:
- Double-click it
- Click on ‘Mixer’
- If you have VLC media player running, it should show up in the mixer:
5. Unmute VLC Media player here and close.
6. Your sound works again! Enjoy the movie!
Go into Settings (Tools > Preferences or CTRL+P) and then select “Reset preferences” all the way at the bottom of the screen.
You can also go into your control panel (Windows key + X > Control Panel or Start menu > Control panel) and select the sound option. It may say “Enhancements for this audio device are causing problems -> Disable”.
If you disable the enhancements your problem may be fixed.
Within VLC player, with the movie playing, go to Audio > Audio Track. Deselect the currently active audio track. Enable it right after and your sound may play again.
Open VLC > Tools > Preferences > Audio > Output module and select WaveOut. As the Device shows up, select “Speakers”. Save.
Note 1: “Enable sound” must be turned on.
Note 2: “Use S/PDIF when available” sometimes needs to be unchecked and sometimes to be checked. Experiment with turning it off and on to see if it helps.
