IR Remote Controller Plugin: How to get it work (with Apple A1156)?

Hi!
Im having very similar issues with the Apple Remote A1294.
I have the receiver on 3,3v - ground - GPIO25
Reinstalled the Plugin and restarted the pi several times.
Like user oha I get feedback in sudo mode2 -d /dev/lirc0 when i press buttons on the remote but there is no reaction in volumio whatsoever.
Do you have any hints? Did I miss something?

Thanks in advance!
