About 1 month ago my receiver started doing something odd. When I press the 'Mute' button on either my Onkyo remote or on my Harmony One the volume jumps all the way to Max. Watching the display on the receiver, I do not see the audio level change. To me it sounds like it is getting a crossed audio signal.

I have 3 HDMI sources and one that is RCA. I have not tested this with my device on the RCA connection, but it is present on all of my HDMI devices.

I have unplugged the receiver for a few minutes and then powered it back on. Other than that I really have no idea what to do.

Could anyone provide assistance?
