 Hey guys, I'm having the exact same problem as ryu87 did.

My HTPC is connected to my LG TV and then that's connected via HDMI ARC to my Pioneer receiver.
Previously, when playing TrueHD files, the receiver just played the audio track in 5.1 Dolby Digital (as it does not support TrueHD). Kodi is set to use 'best match' and 'allow bitstreaming' under audio settings, however I'm sure that doesn't matter now since I'm using DSplayer. In DSplayer settings, I've got everything set to bitstream, except for TrueHD and DTS-HD, as my receiver doesn't support either. When selecting both of those, files with either of those formats are only played in stereo.

I've tried downloading AC3filter and setting it as an external filter in DSplayer. In the AC3filter config, I've ticked 'use SPDIF' in both the 'main' and 'SPDIF' tabs and made sure that 'TrueHD' is selected in the 'Use AC3 filter for:' section in the 'system' tab, however I cannot get this to work. In fact, it's worse when I choose AC3filter because now ALL audio tracks are just output as stereo.

Can somebody tell me how I can get TrueHD audio tracks to output via bitstream to my receiver so they can be played in Dolby Digital? 

You need a filter to convert TrueHD to Dolby Digital. There is no DD core in TrueHD. If you uncheck the bitstream option, it is sent a multichannel PCM. I would think that AC3Filter might do the job, but it might not. Did you add it as an extra filter in DSPlayer and assign it as an audio filter? LAV Filters has mixing options for PCM sources that could be worth trying. It would make more sense to preserve the Dolby Digital track with the rip and select it.
