I'm trying to set up a presentation as follows:
- On startup, the brightsign will output black with an ambient audio track
- On a GPIO event, the ambient audio track will crossfade into an active audio track, and a video corresponding to the active audio track will be cued in sync.
I have no issue integrating the video features, but I can't seem to get any audio tracks to crossfade using an Enhanced Audio zone.
Is there a proper protocol for crossfading audio within Enhanced Audio zones? I've tried making an Audio List object and iterating through that (which I don't think makes as much sense for my purposes) and also changing between audio file objects on a GPIO button event.
The audio sample rates are both 44.1k and I've tried both mp3 and wav formats.
Let me know if there is anything else I can try to get this working properly. Thanks!
