Squeezebox integration stopped playing synced multiroom Squeezelite ESP32

I use HA addon Lyrion Media Server (formerly Logitech Music Server) and squeezebox integration with speakers/players based on Squeezelite ESP32. If they play synced (in multiroom) everytime playing stops within 60 minutes. With no related logs at all. I've tried bunch of sync settings with no difference in result, modified wifi settings and configuration - nothing changed. Than I found that LMS itself with Squeezebox integration uninstalled/disabled handle multiroom smoothly for hours. And when the squeezebox integration is installed back, the problem appears again. It means from my point of view that integration mostlikely overload players with excessive calls and it breaks stream consequently.
Did anybody face the same issue? Does exist any way around?

Edit:
After further experimenting it seems that I found particular devices caused it >> Louder ESP . Once removed from the group, everything is up and running, mostlikely some design problem.
Nonetheless still is not clear, why it happens with Squeezebox integration installed only but without it not.

I can confirm that I'm also having problems with my Squeezebox ESP32 for some time now: the sound cuts out, lags, and stops playing. I have just 1 player, no multiroom. My diagnostics have been limited to verifying that the same internet radio plays normally on my phone or via the website. Then I simply disabled the Lyrion add-on app and the integration, because it didn't feel like I can do anything about it.

Now, after reading your post, I've enabled only the add-on app itself (I didn't know it was possible to not use the integration), and the ESP32 seems to be working fine. So I can confirm the same issue. I have the latest version of the add-on and integration (9.1.1.0).
