So I am confused and there has to be someone with a similar set up that could walk me through this I am looking at adding a sub, but can’t decide on which of the 2 to get at this point. I know this is a stupid question but could it be that because I do not have a surround sound set up that is why it only shows 2.0? This is our first sound bar that we have had and it was originally to deal with getting a better center channel voice level…. Under the next page Advanced Sound Settings the only option that is checked is Play comfort noise on HDMI, Display Volume controller warning Surround Sound There is no options selected.Īs far as I can see is the content when playing gives me the content specifications like 4k, (what ever audio stream on the file) but when I look at the Sonos app when playing a stream I only see PCM 2.0 as the audio. IN looking at the Shield Audio options I have HDMI CEC enabled. The content is a mixture of 4k, 1080p and other formats in a. My content is a mixtures of content sent from the Shield that can be a number of services like Amazon Prime Video, Kodi 20 and our library of content from our NAS devices hooked up through Plex media server. The format that shows on the Beam is PCM 2.0 …. I was having a problem getting any sound at all so I contacted Sonos (great support) and we got the Beam working but I am not sure what audio I am actually getting The LG is set to Sound HDMI to Wired external device. I do not have any Surround sound set up as yet, I will probably get a sub but for now I guess you can say all we have is the Sonos sound bar connected. I have the beam connected through the HDMI 2 Port ARC to the Sonos gen 2 HDMI port. Nvidia Shield is connected to HDMI 3 to my LG Oled C2 TV. Here is how I have it set up as of yesterday:

I guess I'm a bit lost or confused somewhat on the set up so, perhaps you folks could chime in on our set up. There are so many threads and great info here on the forum and I have spent hours reading through them and thanks for all that post.
