I’m having trouble getting 5.1 out of my Xbox one X.



My set up is Xbox one X connect via hdmi to my LG OLED 55b7 then optical to my Sonos sound bar which is linked to a sub and 2 x Sonos ones.



I have selected bitstream and Dolby output on the Xbox but I just get silence. The only way to get any sound out of the Xbox is to select stereo.



I get 5.1 through the TV on other sources like my Sky Q box so I’m sure the TV settings are correct.



Any ideas would be extremely welcome.
