I have an observation about the audio in HD setups, specifically that which comes through the HDMI
cable. In my setup, and others I have seen, there are peripherals connected to the TV through other
inputs, ie., AV, antenna (coax), DVI/VGA audio, component video/audio, etc., and in all cases that I
have personally observed, the HDMI audio is greatly reduced as compared to the other others. It is
so reduced that when the TV's speakers are used, it can be hard to hear when doing other tasks that
involve making everyday "sounds " - cooking, cleaning, etc. Even cranked through external sound
processing it can be extremely reduced, so much so that you have to tell the perennial "gabber" to
shut their yap so you can hear what was just said. Most times the TV is cranked to 100% to hear
things clearly. By contrast, the other inputs work well at between 33% to 50%. It is so bad that I
want to add a preamp before the outboard 5.1 amp so that I don't have to crank it up all the time.
Of course it would need an auto-sense level bypass to keep it from "preamping" the other sources...
That being said, is the HDMI audio so greatly reduced because of the greater dynamic range or is it
just because the levels are kept low? This inquiring mind wants to know.
