timesup:



for the player rpi we do need a boot up delay 
version 9 = system config, webinterface.

https://raspberrypi.stackexchange.com/questions/33037/how-to-add-delay-at-boot

the remotes are boot up and waiting for control. >> sync runs smooth from the beginning.


There are two entries you can add to /boot/config.txt to delay boot.

boot_delay=x
Wait for x seconds in start.elf before loading kernel.
Default 1.

boot_delay_ms=x
Wait for x milliseconds in start.elf before loading kernel.
Default 0.
