The answer is HDMI Output. The highest quality connection between a soundbar and projector is done through HDMI, which is utilized for all other connections.

Here is a general overview of the many soundbar connection types. You will generally find these ports on all types of soundbars.

Where HDMI or SPDIF is not available, an optical link is employed. The most often used connections list places it third. You can seek this connection if your projector or sound bar supports none of the above features.
