Update: first time tried power off, had been on for a few days, going into standby as needed. was playing internet radio. Used VNC to access Slice and powered off. Gave stop (red leds) for stopping the play. Then nothing, and the ethernet port led stayed on. Had to power cycle to restore operating.
Tried power off after boot, after play track and stop, after play track and stop during play, internet radio and stop during play… all resulted in the correct power down sequence, including the red / yellow leds.
It seems like there may be an issue but not easy to recreate. I will wait until it has gone into standby and then retest.
Update 10/10/2017 09:24 Tried power off and it “hung” and did not power down. Last used yesterday to play music files, and used “stop” to stop playing. Change of day? I will try to remember to try it again later after it has been in standby for an hour or so.
Seems like there is something funny here.
