Hi I added new speaker soundtouch 300 . I connected thru HDMI on my sony tv. I can see HDMI3/ARC but when get in to HDMI 3 no on screen display from ST 300 to see the menu , settings , source, bass adjustments , volume etc. But i can play music via sound touch app and receive audio signal when i Connect from tv thru optical cable - aux mode .
Then in order to test next level i connected fire stick on st300 hdmi source and hdmi out to tv , of course i do get fire stick prime video without audio signal.

The SoundTouch 300 does not have an on screen display (None of the Bose Soundbars do). Settings are changed by the SoundTouch app, or via the remote (with lights responding on the soundbar for things like Bass adjustment)
