Hello kanchan16 :smileyhappy:
Welcome to the HP Forums!
I understand there is little sound coming from the speakers of your computer. I will do my best to assist you!
As a quick test, try plugging in earbuds or external speakers. If those work perfectly, then the speakers are probably experiencing a hardware issue. If not, please try the steps in this HP document: No Sound from Speakers (Windows 8)
Although there is some sound from the speakers, the troubleshooting is the same. Please try the steps and let me know the results. Thanks and have a great day! :smileyhappy:
