Perhaps the screw up is on networks side. To ingest, one of the basic checks is audio and video levels, hence tone and bars. If the audio check comes at 100%, then it's possible the intro music would be ok, but rest of the program audio would be at around 115% making the music track sound soft? Just a shot in the dark, I don't watch ABC programming, except for Kimmel and here were/are times when a repeat had/has so much audio compression, one could taste the tin from the tin can he was performing in, courtesy of ABC or KNXV.
