LMS internet radio issue

My setup includes LMS + piCorePlayer with HiFiBerry + squeezelite on windows.
I am experiencing a strange issue: I am unable to stream internet radio stations to piCorePlayer solely.
but if I run squeezelite on windows and synchronize the 2 players - pi plays perfectly.
squeezelite on windows always works.
I have already tried various versions of LMS, the same result.

Thanks for any help.
