- DTS (HD*) 5.1 & 7.1
— My Soundbar only shows “DTS Audio” for HD and compressed but by playing back the 5.1/7.1 HD Test files the channels are mapped correctly and it is highly likely passing through the right format using OMX.amlogic.audio.decoder.dtshd
You really just want the DTS-HD bitstream passed through, not decoded, right?
Seems likely that the Amlogic DTS-HD decoder takes DTS-HD input but only decodes the lossy DTS core.
That's how, e.g., Plex's DCA decoder works.
Otherwise they would need to be paying for a hardware decoder license.
But ultimately, you don't want it decoded by the stick, you want it passed through for the soundbar to decode.
Since your soundbar is reporting DTS, seems like the Amlogic is decoding and re-encoding to DTS at worst, or only the DTS core is getting pass through at best.
I assume you have this plugged into your LG B1 and it's passing audio to the soundbar via eARC? Does the B1 pass lossless audio from an HDMI input out via eARC?
On the Sony A80J/A90J, it supports lossless audio over eARC, but only when played back via internal apps. The Sony OLEDs won't take lossless audio from one HDMI port and pass it out through to the eARC HDMI input. TrueHD audio doesn't play at all and DTS-HD only passes through the DTS core or doesn't play, either. So that may be what's happening here if the B1 behaves the same way.
