I have a Harman Kardon AVR 1610S hooked up to an LG E7 OLED via Optical. My issue is with DTS playback specifically. I have a number of files on my PLEX server that are encoded with DTS sound. When I play them via my TV's internal PLEX app they all play back as DTS and my AVR display shows this. Whenever I play them via Infuse, my AVR displays DOLBY DIGITAL.
I previously thought this was normal as I had read numerous times that the ATV does not support DTS. But a couple days ago I saw a post at a different board from someone claiming that Infuse supports DTS now, even through the ATV, and can passthrough DTS. I've tried setting my ATV audio to Auto but when I play DTS files my AVR continues to display DOLBY DIGITAL. Is this normal? Is my AVR just displaying Dolby even though it's playing DTS because Infuse is sending it LPCM? Apologies if none of this makes sense, I am very much an amateur when it comes to the technical elements of sound output.
Basically, I just want to know if it's possible for my AVR to ever display DTS if I'm watching a DTS encoded file via Infuse on my ATV4K. And if it is, how do I fix my setup to get it?
Thanks to anyone who can offer any help!
