WMUR TV Chan 9 Manchester - National Ads loosing verbal audio

[Sid Schweiger]

>>I noticed at least four times this month that during evening prime time, a few ads on WMUR-DT is lacking the verbal audio, you can only hear the background music, and the music is louder than just background level. 

A quick flip to WCVB-DT playing the same ad at the same time, presents the entire audio package a proper audio levels. I've noticed this on more than one television, and through different digital to analog TV converters.<<

If this is a mono feed of stereo audio, it almost looks like someone at Ch. 9 flipped the phase of one channel, so when the channels are combined anything common to both gets cancelled out.  Even transmitting/listening in stereo, if one channel is 180 degrees out of phase from the other, it won't sound right.
