Hello Everyone, My PC has no sound through speakers but headphones are working fine. I checked all wire connection but not sound in speaker but when I increase the volume too high i could here the sound lightly. What could be the problem. I am using mercury speaker with woofers 980w. It has inbuilt FM radio and amplifier and FM radio is also working fine but when I play movie songs stored in my computer or watch online the speacker does not function so I have to use headphones. Please help me inthis regard, Thank you Lekha.
