Can I get my TV audio wirelessly through Sonos and headphones simultaneously?

Episode 1358 (57:02)

Chuck from Lake Havasu, AZ
Sonos Play:1

Chuck wants to know if he can listen to Leo's show on the Amazon Echo. Leo says yes, but he'll have ask it to listen via TuneIn. Chuck also wants to know if his Mitsubishi rear projection TV can hook up to his Sonos and also play through wireless headphones? Leo says that because of the age, it probably can't play both streams at the same time. If it could, it would have competing volumes.
