Receiving 5.1 channel audio when the Netflix program you're watching has 2 channel audio.

    IMPORTANT: This article applies only to specific products and/or operating systems. Check Applicable Products and Categories for details.

    If the Digital audio out setting in the Sound menu of your TV is set to Auto1 or Auto, the digital out (optical) and HDMI® ARC ports output as 5.1 channel audio regardless of whether the audio of the Netflix® video is 2 channel or 5.1 channel. This is a specification and normal operation for these TV models.

    • For 2021 models (except W8 and X7 series)
      Depending on the Digital audio out settings, audio from digital out (optical) and HDMI ARC is output as follows:
      • Auto1: Dolby Digital®/Dolby Digital Plus™ 5.1 or Dolby Atmos®
      • Auto2: Dolby Atmos
    • For other models:
      When the Digital audio out is set to Auto or Auto1, audio from digital out (optical) and HDMI ARC is output as Dolby Digital/Dolby Digital Plus 5.1.

    Note: The specification is locked to Dolby Digital/Dolby Digital Plus 5.1 or Dolby Atmos and prevents the audio system from muting or producing noise when switching the number of audio channels.
