Re: weird constant hissing sound coming from one speaker

>> there is a constant hissing noise coming from the left speaker
The first thing you have to do is to get the chassis of the machine
earthed properly, either via your power plug or 'crocodile-clipping' a
good earth-wire to the chassis. Later you can screw on a pucca
earth-wire.
Isolate the speaker-out wire from the sound-card alone, see if the
/hiss/ exists. If not go on connecting your peripheral cables and listen
till it appears again.
There are big ferrite beads available. Get a couple of beads through
which you can pass the speaker cable. You need not cut the formed
speaker wire/cable, just loop-string it at the sound-card pin end. If
the hiss has stopped, good.

Isolating the problem is a PITA but fixing it once isolated, is easy. ;)
