Hello ,
I recently added the sonos arc to my TV setup. Below is how I have it hooked up
Xbox Series X to LG C1 HDMI 3
Sonos Arc to LG C1 HDMI 2 (e-arc)
The Sonos Arc seems to detect the right Audio Codecs for Apps that Run Native on WebOS. For e.g. If I play something that is Dolby Atmos on Netflix & I check the Audio-In information on the Sonos S2 App, It tells me it is Dolby Atmos (DD+). Similarly if I Play 5.1 it tell me that it is Dolby Digital 5.1, Or if I play the local news channel, it tells me that the Audio In is Stereo PCM 2.0
I then tried to switch to Xbox and configure it to work correctly. This is what I did
Settings > General > Volume & Audio Output > Speaker Audio > Dolby Atmos for Home Theater (HDMI)
Then go to Advance > Audio options > Allow pass-through.
I then tried to launch games that were Atmos supported (Halo Infinite / Gears 5) I can see the app display the correct codec for Audio In
But when I launched a game that was not supported by Atmos, Sonos still tells me that Audio-In is Dolby Digital
Another test was on the Xbox Plex app, I tried to stream non atmos content, but Sonos still told me that audio in was Atmos.
Why does Sonos not detect the correct Audio Codecs coming from my Xbox?
Thanks
