The sound stopped working on my unit. PANIC!! But I learned to reset the receiver and it brought it back from the dead! It had been slow to start sound, like after a pause or when a disc menu begins. Up to 10 seconds or so. Hope that fixes it all. This horror got me thinking... Can I upgrade this Onkyo 5.1.2 receiver to a Onkyo 7.1.2 receiver and still use all the stuff from this one? I'd get 2 side speakers for the new one.
