No Pre-Cue when Casting

Hi,

I have to do an event where I can only cast to their Sonos via a wifi cast. I’m using Airfoil to cast the DJPAI App (i know about the latency) via “external headphones,” which is one of two options in the settings dropdown for main audio. But when choosing to split the pre-cueing, there is no cueing happening. I’ve tried a few other settings, but nothing seems to get a pre-cue to work. Does anyone else have this issue?

Yes, the volume on the cue is up and using an approved splitter.

I’m on a 2022 MacBook Air M2, Ventura.

Thanks.
