[quote] Combining passthrough and PCM would require a major effort for a clean solution.
Who says you have to combine anything? Better solution is to Split the stream, Sync them, Downmix 1 to 2Ch, and Leave the Other alone. Very little over head if you ask me. DTS is around what 1500kbps? Add that to a Downmixed 2 Channel, and you dont have more than 1800kbps in Audio all together.
[quote]- dvdplayer would be required to handle two codecs simultaneously
They already do that! Always have been doing that. You are confusing codecs with containers.
[quote]- audio engine needs a second instance because a raw stream can't be mixed
No it does not need a "second instance". A raw stream can be multiplied into two sources and ouput simultaneously. BluRay players do that.
[quote]- new methods for synchronizing two audio streams
What new method? It's been done.
[quote]Having HDMI one does not benefit from pass through so this effort would be only for SPDIF, an outdated interface. If you want dual audio with SPDIF, use PCM.
See my post above.
