Good evening
I have a beam sound bar connected to the HDMI arc port on the TV 
The sonos application says DTS 5.1 but if I choose Pcm 2.0 on the TV I get this format
Which is better?

If you want the surrounds to play surround, yes. The 2.0 in PCM 2.0 are just front left and front right. The 5.1 is FR-center-FL and surrounds (plus a Sub).

Depends what you call “better”. PCM 2.0 is an uncompressed stereo 2-channel audio signal. DTS 5.1 has 3 front channels of audio plus 2 rear surround channels and a sub channel.

When you use a beam and two sonos one as surround speakers you need to be in 5.1 for better sound quality?
