How do I fix Apple Music playlist skipping tracks on wired Ethernet connection?

I recently thought I'd compare Apple Music with Amazon and, as I want a high quality source I bought an Apple TV and connected it to an AVR. The TV box has a wired ethernet connection. I then transferred playlists from Amazon with a very high success rate. I tested out the quality which was good and the Atmos material worked as expected. So far, so good.

However, when playing a playlist (unshuffled) I noticed that occasionally one or two tracks would be missed out. I could manually get the tracks to play by going back in the playlist so clearly there is nothing wrong them. This is classical music and is designed to display a progression - it's not acceptable for tracks to be omitted. Clearly it is not a wi-fi issue. How can I resolve this please?

Thanks
