Delay in media player join operation

Hi all,

Since a couple of weeks, I am experiencing a weird issue with one of my Sonos speakers.
For an automation i join them(5) into a group and play a TTS message. Whenever the speaker in my living room is included in the join action, there is a delay of 5 seconds before the join completes and the script proceeds. When that particular speaker is excluded from the join, everything is working fine. (no delay in de the script)

Furthermore, there is no error or waring message of any kind. Using the development tools to trace the timeline does not produce any more insight. Is there another place where i can find more info on the cause of the delay?

From the Sonos app there does not seem to be an issue with this particular speaker. (un) joining is fast as always.

Any ideas anyone?
Thank you!

Erik

Answering my own question: enabled debug logging on the sonos integration which produces a lot more output in the logfiles. For the particular speaker there was a timeout on calling the (un) join operation. Not clear why this happened.

After restarting home assistant every was back to normal again
