PCP 6.0 - Can't play DSD

My apologies if this has been asked, but I tried to follow every guideline I found and I may be missing something.

My setup:

Raspberry 3 + justboom digi hat -> TOSLINK -> RME ADI-2 DAC

Settings:

Picoreplayer 6.0 with pcp-dsdplay extension.
Squeezeboxlite without any -D settings so it should DoP
LMS with DSDPlayer plugin.
-
Now the part that confuses me a little:
In squeezelite settings -D option it says: "Note: LMS requires the DoP patch applied." Is this the DSDPlayer plugin or where is this DoP patch I need to apply exactly? Is not not part of picoreplayer? If not, where I can get it? how to install it?


forgot to mention in LMS, the filetypes dsd and dsf are set to "native" and with their "flac" option they are set to dsdplay.

EDIT:
NEVERMIND, as I typed the latest , I realized I haven't tried to disable "Native" option for DSD formats in LMS File Types, I set it to disable and now it plays.

As I recall reading somewhere squeezelite does not support Native DSD so.. DoP seems to fit.
