I have imported that file and successfully played it. However, I do not currently use an AVR or other device that decodes DTS. MC decodes everything for me. It apparently can read this as DTS, as it plays to my sound card and then to powered speakers without issue.
I tried turning on bitstreaming (Custom > DTS) but MC seemed to ignore it. I think it's because, on playback, MC considers this to be a WAV file. Which is odd because when I look at the file Tags, it says it is a WAV type file with Compression type of DTS.
I'm doing this testing on MC for MC 22.0.30 .
I'm guessing things would be different over a SPDIF connection? (which I'm not using)
Maybe try turning off bitstreaming as a test. Though I'm not sure what will happen since this file presumably will decode to 6 channel PCM, which is too much bandwidth to be sent via SPDIF. Hmm. I'm not sure what the right configuration for this is.
