Last thing last night I rebooted (switched off and on via the front panel switch) the MD600 and set an album playing via a Control:PC end-point.
This morning it had played to the end.

This morning I started playing an album over 30 minutes ago. There have been no interrupts. Yesterday I would have expected at least one, probably two and maybe three.
So the problem is APPARENTLY resolved, presumably by rebooting the MD600 again.
Thinking in retrospect, yesterday the MD600 restarted after the new software was applied but did not actually switch off and on - doh!
So may I suggest that ThePioneer, Rodders and any others with the same symptom restart your MD600s and report back.
I have reviewed the debug information and can see nothing relevant.
Thanks as always for the patient help and support received from this forum.
TL;DR - if it doesn't work, switch it off and on again!
