Reason behind this :
The VLC player has a capacity to boost the volume upto 200-400%. The speakers installed on notebooks are of 4 Ohms speakers & can take volume only upto 100%. In case there is any rise in volume above 100%, the brass caps on the speakers are burnt which in turn damages the speakers. Hence, it is not covered under warranty.
- You can use any other player like K Lite, Try to avoid VLC on your Laptop.
