Google Home - TV False Alerts

Again....last night while watching TV my Google Home started bleeping as if I used the wake words.

I didn't hear anything said in my TV audio that would cause it to respond with the wake word acknowledgment beep. I was watching a show with my full home theater going: A/V receiver powering 2 front satellite speakers and TWO subwoofers. Nothing like "OK Google" or "Hey Google" was said in the program. Yet it went through those responses 3 times.

The G-Home (for short) is located on a chest 4 feet high,  next to my Echo but separated by 6".
The chest's inside my bedroom, next to the doorway which opens out onto the living room. The TV and sound system are in the LR, of course. The door is located in the center of my 1 BR apartment. This centralized location lets me get my voice commands heard by both devices easily.

Amazon's Echo has never behaved like the G-Home. Could the G-Home's mic sensitivity/two mic architecture be the cause of this aberration? The Echo has 7 mics, positioned around the top, while the G-Home's is on that wedge, slanting downward. Maybe that's part of the problem?

I'm going to try a little experiment: swap places with each other. The G-Home's closer to the door.
