is the first version allo isolator compatible with the raspberry pi 4.

is the first version allo isolator compatible with the raspberry pi 4 in combination with the allo piano 2.1.

the problem i get is that the raspberry pi 4 won't start.
have tried volumio and picoreplayer but both without success.
with the raspberry pi 3b + it starts up and no problem.

the raspberry pi 4 works well without the allo isolator and starts up with the allo piano 2.1.

I use a 5 volt 5 ampere linear power supply for the raspberry pi 4 and 10 volt 2 ampere for the allo isolator.
 
 
who has the solution?
 

thank you in advance.

update!

 

i have already got the allo isolator running.

what I have done is put 6 volt on the external battery connector (j29) and now the raspberry pi 4 starts up and the allo isolator works in combination with the allo piano 2.1 raspberry pi 4.

so somehow it doesn't work via the external dc jack (jp2) or something is broken on that part of de isolator.
