I often use the headphone listening feature in the Remote part of the iPhone App to listen to Roku on my bluetooth headphones at night, as not to disturb anybody else in my house.
Sometimes the headphone listening mode reverts back to the TV speakers randomly for one reason or another. (I get a phone call, I pull-up a random Instagram Reel that takes over sound, etc, etc).
It would be great if when that type of disconnect happens and the sound goes back to the TV speakers if they were by default in Mute mode. Because it goes from being super quiet in the house and me watching TV with my headphones, to super loud quickly.
