Hello Kahani Punjab,
My name is Dhiren and I work for the Social Media and Community Team at Dell.
The sound output produced by speakers differ from model to model.
Hence the audio output would be limited depending on its specification.
However , if you are unable to get the desired output from the computers soundcard and default player.
You may try using third party softwares to enhance the output.
There are various third party players available that can boost the audio output.
For example , You can download VLC player . VLC player has an option to boost the volume up to 200% .
You may download VLC player from the below mentioned link
Download VLC Media Player 2.0.2 - FileHippo.com
Note : please check the speakers output specifications before using it on full power since it may damage the speaker if the sound goes beyond the maximum output limit.
