Conq. Unfortunately, it is not supported in newer versions of KODI.

It works great!

Here's a diff.

Also:

$ mkdir -p ${SYSROOT_PREFIX}/usr/include/wavpack
$ cp ${SYSROOT_PREFIX}/usr/include/wavpack.h ${SYSROOT_PREFIX}/usr/include/wavpack/

— otherwise compilation aborts due to missing of wavpack.h (sorry for such a "dirty" hack — again, I'm not a programmer or software developer). Actions with the header file must be performed after the compilation is interrupted due to an error.

I can't believe I did it! Installed, checked — everything works fine.

Higher sampling rate means higher bus traffic on the internal RPi bus. My theory is that it's too high for HDMI output, but maybe OK for the interface. What's your audio output device at the moment?

I use this device connected to the receiver with a TOSLink cable.

I set up an experiment:

I compiled the native mpd (using Ubuntu Server RPI4, the fresh mpd source from the git and instructions for compiling), it took a lot of time, but in the end everything was decoded properly and played without interruptions both via SPDIF and HDMI.

1. Main wiki page is https://wiki.libreelec.tv/development-1/…ds/build-addons. Please read the other "Development" wiki pages too.

2. Create a pull Request on GitHub with your changes.

Unfortunately i'm not a developer. I'll try to compile the «fresh» version of the add-on from the git — but i'm afraid it won't bring any changes. Thanks for answer.

Quote from Da Flex

You're a musician, right? Then chances are, you have an USB audio interface laying around. If the interface works with an ASIO driver, it should work with RPi, too (use a blue USB port to connect). If it's an internal bus issue, then the interface could fix it.

I didn’t understand anything at all. What does the audio interface have to do with it?

Hello!

I installed LibreElec 9.95.1 and mpd (as service addon) and found that when playing WavPack DSD files with a samplerate of more than 384 kHz, the sound is very interrupted. A search on the Internet did not give anything, the mpd settings also did not bring any result. And then I accidentally looked into:

mpd -V

­— and found that it was built without native support for the WavPack format, that is, it decodes it using ffmpeg. And ffmpeg DOES NOT RECOGNIZE DSD compressed with WavPack.

In this regard, two questions:

1. Can I crosscompile «fresh» mpd myself using a PC with Ubuntu 20.04?

2. Are there any plans to officially update the mpd for LibreElec?

Thanks a lot in advance. And sorry about my english.

Here's a test WavPack DSD file.
