I just bought Roku Streambar. I tested to use USB (with audio file) and it worked well while TV is connected with Streambar through HDMI cable.
But when I disconnected TV (unplug HDMI cable), Streambar also turned off. It take USB out and plug it in again but nothing happened.
It seems to me that Streambar can not play music with USB alone ? OR any set up needed ?
Thanks for advise.
