Ethernet disconnects when changing Airplay in iTunes

I have an issue changing my Airplay Speaker in Itunes, I had to do it multiple times before it works.

What is extremely wierd is that Ethernet briefly disconnects every time iTunes changes the speaker.

This is what I'm talking about : Airplay - YouTube

I couldn't reproduce the issue on another mac on the same network, just mine.

iTunes 12.8.0.150

(Sorry for the re-post, I posted from the wrong Apple Account first)

iMac, macOS High Sierra (10.13.6), null

You're right, it is happening also if you choose to send system sound to Airplay.

I've made an interesting discovery today, my Mac supports what they call "AVB/EAV Mode" in Network Preferences / Advanced… / Hardware. If I turn it off, then the Ethernet doesnt disconnect anymore when changing Airplay, but I get no sound either. You might want to give it a shot.

I also opened a bug with Apple under the reference 43242577

Same here.

Are you using a mesh wifi system by chance? I'm using Plume SuperPods and my mac is connected to one of the "satellite" pods via ethernet. This might be moot since I'm pretty sure this worked at some point in the past.

Interestingly enough, this happens only with Airplay 2 compatible devices. It happens with a Sonos One and two Apple TVs, but not with an older Airplay speaker I have or my receiver.

Another discovery : if using just Wifi, or if Wifi is positioned before Ethernet in network preferences, it doesn't happen either. But anytime Ethernet is first, I see the disconnect/reconnect

I get the same disconnect when I change the system audio to an AirPlay 2 device. I think this is an OS level issue, not just iTunes.
