[PROBLEM] Squeezelite + Airplay : Can't work simultaniously?

[S_i_O]

Hi all.

I just switched from piCorePlayer to MoOde and running into an issue and hope you can help me figure it out cause I love MoOde so far!

I have enabled both of the following:
- Squeezlite Renderer (used with LMS)
- Airplay Renderer (for MacBook)

It seems that I can't get both to work at the same time... If both are enabled.

Squeezelite rendering works fine but Airplay won't make a sound even if connected.

If I disable Squeezelite rendering, Airplay starts working... I did not have this issue with piCorePlayer with same hardware (see below)... 
Any ideas what I'm doing wrong?

Hardware:
RPi Zero W with Hifi-Berry DAC+

Thx alot!
