I am with @fritsch on this one. It looks like the AVR decodes this by "accident". I checked the channel status bit on the analyzer and it is set to "linear PCM samples" when you play the wavpack file. It is set to "other than linear PCM" for the WAV file. When I tested this with my Denon X6200W AVR, it did play the wavpack file correctly in DTS, but that was the first time. Now, it is not playing it at all and I didn't change a thing. (Tested with LibreELEC Milhouse build #1230 on Intel Haswell).

Here are two samples for anyone who wants to try this out (must like Mannheim Steamroller )

DTS WAV
DTS Wavpack (MediaInfo detects this as 2 channel PCM)

I also have to say that both the formats do not play in Android (nVIDIA Shield).
