Linn Devices only showing up as AirPlay with QNAP Core after updating to build 1148 [Update Roon to Build 1154 (Linux Release Only)]

This has happened to a few folk here, all (so far as I can see) with QNAP cores. Hopefully the good folk at Roon will get on top of it soon.
I run ROCK on a NUC and have no issues at all with our Linn KDS.
