Squeezebox Radio stops playing alarm track after ~10 seconds

My LMS system has developed a problem recently where my Squeezebox Radios (i.e. more than one of them are doing this) will wake-up on an alarm to play random songs but will then stop playing after about 10 seconds and either switch to the default alarm track or fall silent. Sometimes they will recover at the start of the next song but then they will fall into the same state again. This problem sometimes goes away of it's own accord and everything works fine, then it comes back some days later.

This morning when this occurred I switched my Squeezebox Radio alarm off with the off button and went to look at LMS: LMS thinks the Squeezebox Radio is still on and it is still actively playing music at it. I switched the logging for player.source, player.streaming and player.streaming.direct to debug at that point (log attached) but I don't believe it shows anything unusual.

Nothing has changed in my Squeezebox Radios, all that's happened in the last month or two is that I have updated to LMS 7.9.0 (1488878280 @ Wed Mar 8 14:37:44 CUT 2017) after starting to experience the problem discussed in this thread, which may or may not be related (note that LMS is not unresponsive in this case). LMS is running on a Win10 machine.

Any suggestions as to what I should do to either (a) debug or (b) fix the problem?
