How to use Digital Optical audio cable?

Setup audio for a home theater or audio video receiver


Demystifying the audio
  • The Roku player by default will provide stereo signal, through both composite or HDMI
    • Surround Sound
  • The Roku player does not process surround sound signals (only passthrough via HDMI).
  • Surround sound requires a surround sound capable audio/video receiver (AVR) connected using optical or HDMI cables. Not supported using composite cables.
  • Dolby Digital Plus (DD+) requires an AVR capable of decoding DD+ signal.

    Interesting facts

    In case you have made any modifications to your car, make sure you notify the auto transport company about it in advance. For example, if your vehicle has been lowered or modified for camping purposes, it will add to the auto transport fees. Also remember that most auto transport companies require that you remove top luggage racks and external antennas.
