For example, if this is a wired connection, can you try wireless instead (or vice versa)? I think the issue is probably with your network connection rather than something on the QNAP.

Thanks again, simoncn.
My house has an ethernet backbone, but it can't cover the whole house.
The router, PC, laptop, QNAP NAS are directly connected, as is one Sonos unit that I don't often use directly for output (near the TV via a port switch).
My recollection when setting up the (now old) Sonos system was that it was temperamental about multiple connection to the ethernet backbone. I seem to remember it failed if more than one unit was directly connected, as it wanted to assign one unit as the main internet connection.

In my instance, I could theoretically connect up to three directly, but the other four are located too far from the backbone - but all 6 without direct connection have always worked OK when grouping using the internal Sonos grouping-mesh facility, with no sign of this stutter-stream fail before.

I can try connecting two more, but have a horrible feeling the Sonos may go off and sulk in a corner ;-)
