Oh ... how embarrassing 
When I read the multi-room setup instructions, I read the router requirement for multicast but because I didn't find anything in my router, and multiroom was working initially, I ignored and forgot out it.
After I read your checklist, I looked in more detail into the router setup and found the setting Disable IGMP Proxying which was enabled. According to some websites this relates to multicast.
When I disabled the "disable" setting aka enabled IGMP proxying, multiroom playback works reliably.
Many thanks for your patience!
btw - Any thoughts on running a Pi as UPnP client and MR receiver at the same time?
The idea is to have the option to use either multiroom audio or to send different audio directly to the different receivers (aka rooms). A quick test seemed to work but I was wondering if the two services may create conflicts over time.
