I just finished setting up this record player. The RP3 is hooked up to a Rega Fono MM mk2 preamp, and then into Audioengine A5s. Initially, there was no sound coming from the speakers at all. Thinking the issue was the RCA cables, I went to best buy and bought a new set. Upon connecting the new cables, there was still no sound coming through. Eventually, I spotted an aux cord on the floor. I plugged it into the Audio In jack in the speakers, which somehow triggered sound to start coming from ONE speaker. The volume control has no effect on the sound, and when you touch the other end of the aux cord, it causes hum in the system.
The speakers work normally when using only the aux cord to connect them to my PC and my phone, but seem to not work when using the RCA cables with the RP3 or my Samsung television. Ive been scouring forums trying to find advice, and while I'm not counting on hearing anything different here, I'm desperate!!!
