Soundbar 500, using Alexa as assistant. I add the TV as a device, and for the most part things work well. TV audio plays, Alexa will "Shut off TV (or television)", but she will not "Start up TV (or television)". She says "OK" when asked to start the TV, but nothing happens. Like I said, she will shut it off, but won't start up.
On a related note, why is Alexa so loud, while the TV is normal listening volume? The device is set to volume 25 or so, which is comfortable for watching. However, if you ask Alexa a question, she blasts the answer at what seems like volume 35 or 40.
