Sonos Voice Control + Apple Music: error "file not encoded properly"

Hello

I’m a bit puzzled by an issue which started just few days ago (can’t pinpoint exactly when).

I’ve been using Sonos Voice Control since it’s been released on a Sonos Roam and Sonos One to stream from my Apple Music, and it’s been working perfectly fine.

Then suddenly, when requesting a specific song, I started to see error in the app “Unable to play song xxx, file not encoded correctly”, and nothing plays.

The song is recognised and added properly to the queue, but can’t play. Pressing play button in the app at that stage gives the same error.

If I then try to search the same song through the app and play it, it works perfectly fine. So it’s really just when finding the song through voice assistant that it doesn’t work.

If there’s nothing in the queue to start with and I just say “Hey Sonos, play music” (so nothing specific), it starts playing from my “station” and it works well…

I tried to remove Sonos Voice Assistant and re-add it, I tried to remove Apple Music and re-add it, I tried to restart the devices obviously, I tried to factory reset the Sonos One and re-add it to the system, nothing works.

I contacted Sonos support, but the agent just went through some very basic things like restarting and it’s basically it. I submitted them a diagnostic report, but not sure they did anything with this.

I’m out of idea now. I don’t understand what could have changed if it’s on my side.
