I'm using a Sony BRAVIA TV equipped with Google TV. A Pioneer Elite home theater system is plugged in to the ARC-enabled HDMI port. When I try to adjust the volume with the TV remote, the receiver only changes the volume within a range that isn't perfectly consistent; usually displaying around -45 dB at minimum to -30 dB at maximum, while the TV is displaying a range from 0 at minimum to 100 at maximum (generic volume units, not dB, I assume). This is not the result I expect or want. Sound-wise, the difference between the ends of that range is not dramatic at all. In fact I'd say it's barely noticeable. I would expect the minimum volume to be silent, and the maximum to be damaging to my hearing (because it's the maximum volume the home theater can produce, which is very loud). Any tips or advice?
