Yep, in fact you can experience this wonderful audio level crap-out on many Corus (owned by Shaw) channels, like SHOWCASE, ACTION, and MOVIETIME. It will be there even on brand new episodes of TV shows like MR ROBOT. The value added feature is much different than an audio drop out, in fact it appears to be being done intentionally. You will NOT experience the effect during a commercial EVER. You probably wont even notice if using the speakers built in to the screen, but on a proper HiFi setup, it ranges from mildly distracting to downright catastrophic. These channels are ghetto class anyways so I'm not sure it even matters honestly. If you detected some frustration in my post, you win the interwebs!
