When I power down my TV and Roku Soundbar Pro with the Roku remote power button, after a few seconds I hear the Roku "blip" sound and then TV powers back on. I was forced to change the settings in the Roku settings menu so that it will not power the tv, but every few seconds the Soundbar Pro makes the "blip" sound which I assume is the problem.
I have an older Sharp Aquos Quantron. And I just received my SoundBar Pro. I did try restarting the Roku and also checked for the latest updates. I used the included HDMI cable.
