Are you streaming Netflix on another streaming device or are you using the TV’s native Netflix app?

I am using TV’s native app.

You shouldn’t be getting multichannel PCM 5.1 from the TV’s native Netflix app. You should be getting Dolby Digital Plus or Dolby Atmos. Make sure your TV settings are set to this:

HDMI Input Audio Format: Bitstream

Digital Sound Output: Pass Through

HDMI input audio format is Bitstream and sound output is Pass Through ...

Strange. What model LG TV do you have?

If you switch back to a Dolby Atmos source, do you hear audio from the surround speakers? Is the Sub audio working?

Its a LG OLED65A13LA model.

If I switch back to Atmos, everything just works - surrounds and sub...

I think the series I am watching just does not support surround sound (Trailer Park Boys).

Can anyone check if they get PCM 5.1 when watching this ?

I just tested Trailer Park Boys. Seasons 1-7 are in Stereo PCM and seasons 8-12 are in Dolby Digital Plus 5.1. So you probably won’t hear any surround audio from the first seven seasons.

If you are getting Dolby Multichannel PCM 5.1, your TV is doing some sort of audio conversion of the original audio.

Thanks for all the help!
