Author Topic: DSD Wavpack muxed inside MKV - playback forces PCM conversion  (Read 71 times)

I have a .WV file with a DSD256 compressed. The audio is from a video. It plays perfectly as a .WV file to a DSD DAC using DoP. Audio Settings are correct: DSP & output format is unchecked.  Bitstreaming: DSD (Yes). Audio Path is correct.
I mux the .WV and original video into an MKV. I verify the muxed audio track is still a DSD Wavpack.

When I try to play the MKV, nothing I can do prevents MC from forcing the audio to be converted to PCM (176.4kHz) ...i notice the Output Format sample rate table has been automatically changed and audio path indicates the DSD256 stream is being converted to PCM.

How can I force the MKV's WavPack audio track (DSD256) to remain unaffected and just passed to the DSD DAC?
Thanks

Don't think DSD audio muxed with a video is supported, simply because DSD with video isn't a thing.

Awesome Donkey is correct, this is not a supported scenario for bitstreaming, and unlikely to change due to the way the video engine works, and that it is essentially double-packed (DSD in Wavpack in MKV).
