I’m working with a network configuration for an organization that has a decent sized Dante network. The original configuration had everything in a large conference arena, and the dante equipment was connected with a $40 1Gb monoprice switch. They want to move some of their audio equipment to another conference room and bridge the audio. I analyzed the traffic and it’s about 80Mbps, so I’m thinking it’s gonna be an easy thing to just put this on their 1Gb unifi switches. I did a test connection on a single switch before I moved the equipment and all worked on one unifi switch.
Then my problems began. The final path between conference rooms is a three switch hop. Not a problem, right? The Dante spec gives specs for up to 10 switch hops. However, I’ve had problems getting an audio sync due to timing issues. It turns out that Dante uses PTP (Precision Time Protocol) to sync the audio devices. I’ve got the setup working with a few dumb switches, but I can’t get the unifi switches to work.
From what I can tell on my reading so far, a switch that truly supports PTP will adjust the timing as it passes the traffic. Well, I can assure you that the $40 monoprice switches are not doing this. PTP can be somewhat forgiving as long as devices aren’t royally screwing with the signals, evidently. What I can’t figure out is what settings I might could utilize on the unifi switches to enable the Dante to work. I’ve got a rather stupid looking workaround for now, but it’s killing me not to have a working solution with better hardware.
