Do I need HDMI ARC or can I use optical?

HDMI ARC is preferred — it carries audio from your TV and allows CEC control (TV remote controls soundbar volume). Optical works fine for audio but doesn't support CEC or eARC's higher bandwidth. Most budget soundbars include both.

Will a soundbar work with any TV?

Yes — every modern TV has either HDMI ARC, optical, or 3.5mm audio output. Bluetooth is a backup option for older TVs. Check that your soundbar includes the cable for your TV's output.
