Make sure your wavpack-decoder is version 5.0 minimum.

[harbinbeer]

libwavpack.so.1.2.0 is the new lib of Wavpack v5.1.0

[mistepien]

Are you sure that mpd was compiled with proper headers of wavpack? This is not enough to symlink libwavpack to new version of library.

[MaxKellermann]

Closing, because this looks like a libwavpack configuration problem, and not related to MPD.

Anyone ever played DSD@Wavpack? http://www.wavpack.com/WavPack5PortingGuide.pdf

From an application point of view under WavPack, DSD audio “samples” are actually a byte of 8 consecutive 1-bit samples. That means, for example, that seeking can only be performed to an 8-sample boundary, and that functions to obtain the sample count in a file will actually be querying the number of sample “bytes” in the file. This was chosen to eliminate the strange situation where a seek would be performed to a “mid-byte” position and all samples retrieved after that would be shuffled around, and also because WavPack is actually storing DSD samples as bytes. This also means that the sample rate returned by WavpackGetSampleRate() is the number of bytes per second, not bits per second (however there is a new function WavpackGetNativeSampleRate() that avoids this but should only be used for reporting the sample rate to the user). An application has three options for dealing with WavPack files containing DSD audio. The first is to do nothing, in which case WavPack will report an error when attempting to open such a file (the error is “not configured to handle DSD WavPack files!”). This is what unmodified applications will see. The second option is to include the flag OPEN_AS_PCM when opening the WavPack file. In this case, the DSD file will be appear as 24-bit PCM, and will automatically be decimated 8X during decoding. This allows applications that cannot natively handle DSD audio to do so. Note that this will still result in a very high sampling rate (352.8 kHz for DSD64) with lots of remaining quantization noise and should therefore be further down-sampled before use. This is how the WavPack Cool Edit and Audition filters and the winamp plugin handle DSD audio (the winamp plugin downsamples another 4x for playback while the Audition filters assume that the user will do this as they see fit). In this mode WavpackGetBitsPerSample() returns 24 and WavpackGetBytesPerSample() returns 3 when a DSD file is opened. The third option is to include the flag OPEN_DSD_NATIVE when opening the WavPack file. In this case, the DSD file will be appear as 8-bit PCM, but each 8-bit PCM sample returned will actually be 8 consecutive 1-bit DSD samples, with the MSB being first temporally (same as DSDIFF). The channels are interleaved at the sample level (just like PCM) and these 8-bit DSD bytes are returned in the lower 8 bits of 32-bit integers (just like 8-bit PCM is returned). In this mode WavpackGetBitsPerSample() returns 8 and WavpackGetBytesPerSample() returns 1 when a DSD file is opened.

Yes, I play DSD wavpack files all the time. It is supported since 0.20 and works very fine. Support of DSD wavpack was my feature ticket

I can confirm that DSD wavpack play back perfectly. Maybe you have a problem when creating the wavpacks?
