I'm getting a constant high pitched squeal through my HK Soundsticks
Texto:
As the title says, I'm getting a high pitched squeal that remains consistent regardless of volume settings. I've tried different USB ports between my display monitor and my iMac to determine it wasn't an audio output on the device, and I plugged in different speakers that also use RCA jacks to make sure it wasn't just the speakers, which it wasn't. With the replacement speakers, I still got the same high pitched interference.
I do hear it coming from the sub as well, so I'm not sure if there's some sort of output amp in there that may be going bad, but I've tried everything I could by process of elimination to determine where the issue may lie. Anyone had experience with these?
