Sonos just introduced DTS support with its latest update.
My current setup: LG C9 connected to Sonos Playbar (optical) and ATV 4K connected to LG C9 via HDMI.
Playing back movies with DTS (not HD formats) I expected to see DTS output in my Sonos app.
I double-checked with the Infuse website and it says that it is recommended to set audio output for the Apple TV to AUTO.
Now here are my results:
Apple TV set to AUTO: Sonos app says PCM Stereo
Apple TV set to DD 5.1: Sonos app displays Dolby Digital 5.1 (expected, since it forces audio to play in DD 5.1)
The latter has been my standard setting for a while, since my Sonos Playbar hasn’t been able (up
to now) to do anything with DTS audio. So basically I always get DD 5.1 output, no matter if source audio has Dolby, DTS or HD audio.
I really kind of expected to see DTS being played back after the Update.
Any fellow Sonos owners here who can give me a hint where I am wrong?
Somehow I figure that the Sonos DTS-Update will do nothing at all for me with my current setup
Is there a root cause? Is it simply that the Apple TV converts everything to LPCM? But if so, it is supposed to be multi-chan LPMC. Why on earth does my Sonos app shows Stereo PCM then? Shouldn’t it at least say sth. like Multi PCM?
I am confused; appreciate your help!
