How to do a multi-speaker hallway

I am trying to emulate a real-world situation where the player walks down a hallway with a right-turn mid way. The hallway has speakers every 30 feet or so playing music at a modest level.
I can’t accomplish this using a single sound with Attenuation because there isn’t an attenuation shape that matches.
If I use multiple sounds playing the same sound source, the speakers are out of sync. I know I need to use ‘play when silent’, but even then when speakers overlap I get an annoying double-sound.
I’ve been able to accomplish this in a testbed situation, but not in-game.
(And it seems to work when stepping through in debug, but not when running in real-time)

Any hints?

Try using a Sequence node to play them all at once.

Thank You. Seems to work great.
