I've been mixing for under a week now (only with headphones), and I want to share my mixing with my roommates. I've got some speakers and a boombox (logitech) which usually connect to my laptop which I am now trying to connect to the SR. Whenever I unplug the speakers from my PC and plug in the male 1/8" to the speaker's headphone input I get the LED's on the SR indicating that there is a song playing, and that I can't hear it. Also, whenever I do this and have my headphones connected, I can hear perfectly (through the headphones). If anyone has had trouble with this, and has now resolved it, I would greatly appreciate any help from you, the forum. Thank you.

P.S. Should I use instead a female to 2 RCA males, so that I connect the speakers with the Aux cable that usually goes into my PC?
