Hi everyone,
I’ve been doing some sound tests with my Sonos Arc Ultra + Sub Mini + two Ones setup and noticed something interesting.
When I use the Netflix app directly on my Samsung Q95T TV, the Sonos app reports Dolby Multichannel PCM 5.1.
When I use Netflix on my Apple TV 4K (3rd gen), Sonos reports Dolby Digital 5.1 instead.
On the TV, HDMI audio is set to Auto (no passthrough option available), and HDMI eARC is enabled.
To my ears, the audio from the TV’s built-in Netflix app sounds more “powerful” compared to the Apple TV.
So I’m wondering:
Which format is technically better: Dolby Multichannel PCM 5.1 or Dolby Digital 5.1?
Is one higher quality than the other?
Are there any settings I should tweak on the TV or Apple TV to get the best possible audio?
