Quoted from finman2000:
Yes, I had an issue that only affected the right channel. So, I'm sure left channel only is a possibility.
Well I tried a different 3.5mm cable from the pink jack to the green jack on the back of the box = no difference. Static still there
Unplugged sub cable = no difference
Tried running the RCA cables directly from speakers to the sound board = no difference
replaced the RCA cables with other cables = no difference
Wiggled around the USB cable thing a bit, but didn't remove itas I was afraid something might blow up = no difference
Well one difference. I now have static coming about evenly out of both speakers where before it was just the left speaker. It isn't super loud, but from 30 feet away across a silent room you can hear it.
Are pinball machines supposed to have that static/crackle hum all the time? Or are they supposed to be dead silent like when I hit the mute button on the front?
Still haven't heard back from my JJP ticket.
EDIT: JJP support actually did get right back to me 2 weeks ago. I just didn't know the response would be to the ticket itself so I never checked it, I was expecting an email. The delay is all my fault.
