Confused myself with surround sound.

[Tafster]

Could someone give me the correct settings in sound for my setup please as i have googled it and confused myself, which is annoying as I'm usually ok with this kind if thing (I'm putting it down to lack of sleep)

In one room I have sky stream (Ethernet via power line) with a Samsung S95B, i have it connected to a Sonos Arc with a Sonos mini sub and two Sonos One SL surround speakers.

In the other room I have sky stream (Ethernet via power line) connected to a Samsung QN90B with a Sonos Beam 2

On stream I have UHD & Atmos add on's.

So my question is, for the very best sound results should I choose in stream sound settings, Auto, Dolby Digital Plus or pass through for each set up ?

TIA

I no longer have Stream, but I did have it for about 3-4 months. However, I did have most of the Sonos gear you've listed connected to Stream at the time. I found the best sound setting on the Stream was Auto. In fact, if I selected pass through on the Stream settings I got no sound at all. My TV is an LG and the sound settings are set to pass-through there. With those settings everything seemed to sound great, along with the excellent Stream picture quality.

As long as the HDMI handshakes between your devices are solid, Auto on the puck sound settings should send the best possible sound quality to your Sonos devices.
