I recently upgraded my existing Playbar sound system with the Boost, and then did the S2 update. However, I do not get sound when trying to play certain streaming channels--such as Hulu, Showtime, Amazon Prime, and others. Other channels like Netflix and HBO Now are fine and I can get sound through my Playbar. I’ve made sure the TV audio settings are correctly set, and I’ve followed all the instructions on this page: https://support.sonos.com/s/article/3339
But, still no audio on most of our streaming channels (which we get through a Roku device). Any advice?
