Multichannel audio playback

Anyone tried to playback a multichannel audio file (5.1) through AudioFinder?
Audio channel legs (L,R,C,Lfe,Ls,Rs) are not routed to the appropriate outputs (Catalina).
Setup is as follows:
· Multi channel CoreAudio sound card (RME HDSP MADI Interface)
· AudioMidiSetup -> Speaker Setup -> 5.1 as the output format
· channels are correctly routed to reach of the respective speaker feeds
Playback resulting in sounds coming only out of left and right outputs (stereo)

Thanks for input … Cheers

Hey - I’m seeing the same with 6.06.
