Yes. However, only Roku 2 series players support 5.1 audio streaming. Not all Netflix titles are available in 5.1 audio. If a movie or TV show title is available in 5.1 audio, a 5.1 icon will be displayed on that title’s details screen.
To turn on 5.1 audio, first select a title you wish to watch instantly. Next, select audio & subtitles to select the 5.1 audio option, if one is available. Once selected, press BACK on your Roku remote to exit the audio & subtitles selection screen.
Please note that you must have your Roku player connected directly to a receiver capable of decoding Dolby Digital Plus. Also, you must ensure your audio mode is set to 5.1 surround. From the Roku home screen, select Settings > Audio mode > 5.1 surround.
