A:AnswerYes. Besides optical, this soundbar also has HDMI, a 3.5mm headphone style connection, and blutooth, all of which your AiO is likely to support
A:AnswerTry using your Signa S2 remote once right when you turn your TV on. After that, use your TV or streaming remote to change volume and see if the volume number is displayed. This process works for my set up. Good luck.
