Need similar TrueHD, DTSHD changes since it’s not supported as other manufacturers.
Only DTS, AC3 audio can currently passthrough not 8 channel like TrueHD, DTSHD-MA

Audio decoders improvements
Some improvements to high-resolution audio playback
Fixed some IEC audio passthrough streams
TrueHD audio passthrough improvements
Added support for some TrueHD streams in native video players
Added transcoding of TrueHD pass-through audio streams to AC3 for S/PDIF
Fixed support of some DTS-HD audio tracks
Added support for DTS-HD audio passthrough in native video players
Now S/PDIF plays DTS core from DTS-HD audio passthrough stream
Allowed playback of DTS-HD HRA audio passthrough streams via S/PDIF
