Vizio TruVolume working backwards!!??
Found this thread from a search due to similar issues I'm having with Vizio SRS Tru Volume... Using Amazon FireTV box and the volume of different episodes of same shows on Hulu, Amazon video, Netflix, Crackle vary many times... And the dialog is very muted or subdued while the sound effects and background music is pronounced.
Turned SRS Tru Volume off and these problems cease.
