Hi @Saqlain burki, 

For the first question, you’ll just need to have ARC and CEC enabled on the LG TV as that will allow you to receive Dolby Atmos. This setting is called Simplink, sometimes it’s in different areas but these are the general steps to enable this:

ENABLE ARC

Sound menu→ Select Audio Out (Optical/HDMI ARC). → Turn on Simplink

On some older LG TVs: Sound menu→ Turn on ARC Mode. → Turn off TV Speakers.

On some TVs you may need to select External Audio (Optical/HDMI).

ENABLE CEC

Home Button on remote → Settings → Simplink → Enable

OR

Home Button on remote → Input Methods → Green Button for Simplink → Enable

Your other two questions are more Playstation related than Sonos related. Our community members may have some information on how to set these up, but you may have more luck with Playstation support.

I hope this helps!
