I have been having issues with playing Audible on my Sonos Roam via Alexa. I use the command “Alexa, play Audible” but after 3-4 minutes the audiobook will stop. On the Sonos app I get the following message: “Unable to play <Audiobook Chapter> - the song is not encoded properly.” Sometimes Audible will skip ahead 2 chapters after the message, but mostly the audiobook stops completely.
This issue only happens if I play Audible via an Alexa command. There are no issues as far as I can tell with other services (eg Spotify, iHeartRadio, etc) or playing Audible through my phone.
Below are the following solutions I’ve tried and their respective diagnostic confirmation numbers after the issue reoccurred:
Completely reset the speaker - 1687113073 and 1909624914
Switched speaker to a 2.4 Wi-Fi network - 1319891684
Reset my Wi-Fi router - 267135584
