Hi I have just got a new 2.1 philips speakers. When i fix this speaker to my desktop pc and listen to song I can hear some hissing sound. Then i tried fixing the speaker to my laptob, using same song, but the hissing sound was now there. Please help me to troubleshoot the hissing dound on my desktop pc.

is the hissing there when you arent playing any sound? how about if you don not connect the speakers to a computer? if so, its the speakers generating the hiss. some PC speakers do that, it sux.
if not, then the hissing is in the song file. try another song, see if its there.

Well the noice is more of cracking.Tried out the same sony both on laptop and desktop. Speaker connected to desktop has got cracking sound, but when tried with laptop the sound is fine without cracking.

cracking, as you describe, sounds like its distortion to me. try turning down the volume on the desktop in software (the main out volume). if that clears up the sound, then just turn up the speakers. it would be unusual, but the signal coming out of the PC could be overdriving the speakers.
does this happen from all kinds of music, just stuff with lots of bass, etc?
