When you "disconnect the jack" does that mean you are disconnecting the speaker or headphones from the PC?
If so then it tells you that the speakers/heaphones are not the problem. You can double check that by using it with your phone.
If you are using a powered speaker make sure that the speaker volume isn't turned way down so you have to turn the PC volume way up and vice versa.
You may have a hardware problem. If you are using motherboard audio then a soundcard or USB DAC or DAC/Headphone amp would bypass that.

yep my headphone my speakers all have hissing if i use the mobo's audio port even in the front audio but you can hear small amount of clear low sound if i play music in max volume. yep thats what i think the onboard sound card is the problem. thank you.
