Hi there,
I have just got the Sonos ARC and the audio format I get is Dolby Multichannel PCM 5.1 but no Dolby atmos. My tv Philip 58PUS8556/12 support Dolby Atmos, the hdmi is connected in the e-arc and enable it. I have tried several times with different films without success, Can anyone assist me?
thanks
Make sure the Digital Out Format setting on the TV is set to Multichannel (bypass). And set eARC mode to Automatic.
Yes, both are Ok 
What are some of the specific Dolby Atmos sources you are testing? From what app? From what device?
I have tried for example watching the Irishman through Netflix with my Philip 58PUS8556/12. I just receive Dolby Multichannel pcm 5.1
Do you have a Netflix premium subscription? This is required for Dolby Atmos audio.
The fact that you are getting Dolby Multichannel PCM audio tells me that your TV settings still aren’t correct. Make sure the Digital Out Format setting on the TV is set to Multichannel (BYPASS) not just Multichannel.
Netflix is premium.
see below the multichannel options
Select Multicanal (derivacion). Also be sure to play the ORIGINAL language audio track.
It was the audio, I was not playing the original one. You rock mate
thanks very much
