After many troubling hours trying to track down a very similar issue when I upgraded my speakers, much to my chagrin, I discovered I'd plugged the lead on the back of the speaker into input 2 rather than input 1. Lesson learned for the umpteenth time to look at the simplest and most logical solution first. In my case it was user error.

Hope that helps.

Cheers,
John
