i just started to do this and am having an absolute blast working on this. first off, im on a college students budget, i'm a server at a bar, so i cant spend to much on this $) right now i have an old computer that used to be my granddad's before he died, a old reciever that i bought for 50$ (but i can take it back and bring more money to upgrade the reciever whenever and as many times as i need), a on-board soundcard, and two big speakers that my parents gave to me (there pretty old). right now, i have everything hooked up and really cant complain. i got rid of all that nasty interference noise from the computer using a ground loop isolator: http://www.epanorama.net/documents/groundloop/home_solving.html now heres my problem. forsome reason only one side of the set-up is working. right now outta 4 speaker outputs on my reciever (2 for left and 2 for right) i have both my speaker's plugged into the rightside. its like my computer is only putting out a mono output, instead of a stereo output. is it my soundcard? the reciever?
