Maybe some day they will figure out sound leveling. I've seen this issue across all makers.
Comcast is doing the same thing.
I am having problems with the volume dropping on my digital tv system. I have digital tv from time warner, sony home theatre & samsung lcd tv. I have all the components hooked up with hdmi 1.3a cables. On time warner you have a choice of watching non-digital channel or digital channel. When I am watching "non" digital channel the volume is at around 17 and when I switch to same channel but digital signal the picture improves a 1000 percent while the sound diminishes by 50%, I have to turn volume up to 34 or 35 in order to hear the sound on the digital channel.
Any ideas of why this is happening?
