I'm getting an HDCP error when turning on Roku with my Soundbar 700 connected to ARC to the TV. Was wondering if this issue is caused by the soundbar b/c it never showed up before. Is the Soundbar 700 HDCP 2.2 compliant? Can't find anything on the Bose website
I would reconnect both ends of the HDMI cable that run between the Roku and the TV. That error is looking for something in the chain of connection that is passing the video. Since the soundbar is connected via arch, the TV should be passing on the audio signal from there which takes the soundbar out of the chain that HDCP is looking for. I hope this helps!
