Samsung Q950A (1 Viewer)

[knorr1027]

I am planning to purchase the Samsung Q950A soundbar. All the reviews convinced me that this soundbar is the one for me after 27 years as a home theater buff. My concern is the inputs. Maybe I'm missing something but I have multiple streaming devices (Roku, Sony UHD player, and Amazon 4k FireStick.). Where do I plug these in if the soundbar has only 1 or 2 HDMI inputs? Also, I have a 4K tv and a 4K projector. How can I be able to switch them back and forth? Any thoughts? Thanks.
