v17 dsf files: Loud transient noise between 5.1 tracks

I am a Kodi newbie and have a problem playing dsf multichannel files.

A single file is played back without any problems.
(Kodi 17 / Libreelec / RPi)
When playing several files in a row, however, there is a loud, unpleasant noise between the titles.
Could be harmful to the speakers in a long run.
2 channel titles are not affected.
A friend's Oppo (BD103?) plays everything without any problems.

The following variants were tested:

dsf 5.1 (dst) >> Transient
dsf 5.1 (dsd) >> Transient
dsf 2.0 (dst) >> OK
dsf 2.0 (dsd) >> OK

To avoid an error in the files, each title was generated in two different ways without changing behavior.

At first, i wanted to create an issue on Github.
That doesn't seem possible for Kodi.

However, I found an interesting post in another project:

"It appears some players cannot handle zero padding at the tail of a DSF correctly. 
I have implemented an option to avoid zero padding while maintaining gap-less data and created a pull request.  "

So i searched for some infos regarding dsf zero padding:

it says:
Block size per channel is fixed, so please fill ZERO(0x00) for unused sample data area in the block

So zero padding is standard for dsf files and avoid it would'nt be the right way.
If this is the root cause for the transient noise between the tracks, i would be very happy if the bug could be fixed (-;

found no threads by searching with keywords like "dsf transient noise" / "dsf noise"
So  i don't know if this is the right place to open an issue.
If not, please point me into the right direction.
