This article has information on some of the steps to resolve audio issues while using VLC Media Player (India, Vietnam) and BaoFeng, Xunlei, SheShou and Baidu media players (China).
Issue with increased volume while using VLC Media Player
When using VLC Media Player, volume can be increased to maximum output. This eventually distorts the speaker output.
If audio/video playback is continuously done using VLC Media Player with volume higher than 100% over a period of time, even if the volume is kept at a lower level later, sound would be distorted. This distortion is permanent.
Why does this happen?
Some audio applications like VLC Media Player will allow large power output through speaker, approximately 200% to 400% of original sound output. In this situation, excessive usage may damage the speaker.
