Advice needed for correct parameters for Wavpack DSD encoding in Media Center

<< < (3/4) > >>

Matt:
If you're having a problem playing WavPack DSD files on a DSD capable DAC, please ensure you have build 23.0.20 (or newer) installed.  We just tested here and it seemed to work well.

Just let us know if your experience varies.

I have 23.0.22 on Windows and 23.0.20 on Mac and I have the same results on each. My DSD DAC is a Schiit Loki and it only does DSD decoding DSD64 to be specific and in DOP format only if the device your using uses DOP for DSD then I don't know why mine wouldn't work. Here is a log if it helps.

Hi Matt. I just tried both the Windows version 23.0.22 and Mac 23.0.20 using identical files (audio-wise) in WavPack, DFF, and DSF formats. This was done in both PCM and bitstreaming modes using my Teac UD-301 connected USB. On Windows I use the Teac ASIO USB driver and on Mac there's no special driver and I select it as TEAC USB AUDIO DEVICE and I select the Mac specific things required to get bitstreaming to work (integer, 176 kHz, etc.)

On Windows everything works in both PCM and bitstreaming mode. The only difference I noticed was that in PCM mode the WavPack files are shown as 352.8 kHz 24bit files while the DFF and DSF files are shown as 64bit files (which I imagine is just what the plugin is providing for PCM playback).

On Mac, PCM mode works fine for all 3 files, and I get the same 24bit / 64bit discrepancy (and it still doesn't make any difference) but everything else is the same

However, trying bitstreaming on Mac I get different results for the WavPack files only. The DFF and DSF files work fine whereas the WavPack file seems to play (it progresses at the right rate) but the DAC does not lock and there is no sound. Further, when I look at the audio format I get completely different stuff shown for both input and output (compared to the formats that work):

DFF, DSF:
input: DoP 2.8 MHz 1bit 2ch from source format DFF (or DSF)
output: DoP 2.8 MHz 1bit (padded) 2ch using Core Audio (bitstreaming)

WavPack:
input: DSD 2.8 MHz 1bit 2ch from source format WV
output: 352.8 kHz 24-bit (padded) 2ch using Core Audio (bitstreaming)

Please let me know if I can provide any other information or help in any other way.

Thanks!

Hi, I have the same problem, in my case with mac version 23.0.20 when playing via DNLA (using DSD bitstreaming) to a renderer on another computer: DSF files play OK as DSD; however the 24/352 WavPack files containing the same DSD play as PCM.

Only difference with what bryant reported is that I am able to listen to the WavPack files if I switch my Lampizator DAC to PCM. However, I would like it to play them as DSD.

Any advise will be very welcome!

bob:
The wavpack input plugin doesn't currently do DoP encapsulation.
Since the Mac can't play native DSD we are left with a catch-22.
We are looking into making the wavepack plugin do DoP encapsulation.
