Hello guys. Good morning/evening wherever you maybe 
just want to ask about my sonos app,there’s this written under the TV says stereo pcm? Then checked it on my tv settings all I’ve got is pcm or dolby 2.0. Just want to ask which is better to use? Tried choosing the dolby but it felt like it make my beam louder than pcm but lacking of surrounds. Hope you can help me. Thanks and stay safe

PCM is uncompressed audio while Dolby 2.0 has been compressed. Stick with the PCM setting unless you think the Dolby 2.0 setting sounds better to your ears.
Thanks for your time to reply I might stick with the pcm 
thanks again and stay safe 
The audio arrives in whatever format the broadcaster chooses. In the UK HD channels frequently use DD2.0.
The TV setting won't make any difference overall. Either the TV decodes DD to PCM or the Beam does.
The setting is there to force the TV to output PCM for those devices which don’t support Dolby.
Nice! Thanks for the info and stay safe
