C4 system that has been installed for some time. Running latest OS 3.4.x / controller is a EA5. Nearly everything is wired except we have several Triad One's *wireless* in rooms without ethernet connections. Those are the rooms that we tend to do a lot of Airplay to. Each room has its own ShairBridge driver setup, unique broadcast name, etc. Network is unifi APs with Pakedge switches, pfsense router.
Here's the issue. Starting playback from say an iphone using Airplay to the room takes a good 5-7 seconds before sound is heard. Sometimes that could be 10 seconds. Shuttling tracks forward/reverse, starting a different track, etc. also takes 5-10 seconds.
It "feels like" given the network and hardware in play that is an absurdly long buffer time.
Q - normal? if not, where can we start poking around to shorten the time between start and hearing playback?
Thanks!
