Actually... I found that AC3File handles the WAV sources just fine. So, I'm going to modify my instructions above to:
1. Make sure you have FFDSHOW installed and working.
2. Install AC3File from here:
http://ac3filter.net/projects/ac3file/releases3. In MC, go to Tools > Options > File Types
4. Select DTS Audio from the Audio list, and choose JRiver audio engine (DirectShow) as the playback method.
5. Set Source Filter set to AC3File.
6. Set Other Filters to ffdshow Audio Decoder.
7. Hit the Configure button and open the FFDSHOW Configuration Utility.
8. In the FFDSHOW dialog, select the Codecs "tab" from the left-hand nav.
9. Make sure the DTS decoder is set to libdts and the "check for DTS in WAV" option is ENABLED (should be by default with CCCP).
10. Scroll all the way down in the codecs list and set Uncompressed to "All Supported".
11. ??
12. Profit!!
The beauty is that this will work
BOTH for DTS encoded WAV files (DTS-WAV, like the sample I linked to above) and for raw DTS files like Alex posted. I just tested here on my system with both types of files and it works fine.
You could, of course, use AC3Filter instead of FFDSHOW for the decode filter, if you so desire. I don't really see much benefit to AC3Filter over FFDSHOW though, and it is just one less thing to install and maintain to use FFDSHOW instead.
