Why can't you use the TV's speakers? Or the audio output from the TV?
Mainly the audio often has too much dynamic range so I like to compress it quite a bit. Otherwise the louder sounds are crazy and then the dialog is sometimes illegible against the background noise, HVAC, computers etc. without making the audio annoyingly loud overall. It is especially bad at night and if I fall asleep on the sofa there will be an awakening blast for sure.
The second reason is that the built-in audio is kind of crappy on the LCDs. I want to take the audio output of the TV, run it through the compressor, and then to amplified speakers. A problem is that the audio outputs are full volume. On the old analog LCD TV I could use both internal and external speakers in a kind of balance, but there is an echo with the HDMI LCD. I never thought the SD to HD replacements would all be so damned complicated, but I cannot stop now. ale:
