Since my Roku 2 (2720) will no longer be supported by Amazon Video come Nov 1, I need to purchase a new Roku. I want to be able to connect by Bose sound system to the Roku so that when I am streaming, the sound comes through the Bose. I do this on my current Roku 2 via the audio ports. It appears that the latest Roku devices don't have audio ports, or am I wrong? The 4K Plus certainly doesn't. Would the Roku Ultra be able to do this?
