NO SOUND IN VLC PLAYER
Problem-While playing .3gp,mp4 videos, no sound is heard even when the speakers are on.
1. Check for the system volume and confirm that it is not muted.
2. If the video you are playing is of very low quality or if it is a mobile video, then VLC player plays the video with no sound.
3. You must download high resolution videos for your PC/Laptop and the sound will be played automatically.
