Suppose 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.
- If your TV doesn't have Auto2 in the Digital audio out settings, audio from optical digital out/ARC is output as Dolby Digital/Dolby Digital Plus 5.1ch.
- 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.
