Hi Frank,
Sorry for provide insufficient information.
Here is the findings and debug info.
1. When I use iPad to control, once select I2S to ODROID HifiShield(I2S),
Funding one: system hanged
I cannot take control with iPad or even I start browser with PC. so I cannot collect debug info.
Funding two: counter showing first song play non-stop, second song on play list will not play
when I use PC to control , it is not the case.
After I setup I2S output option. I can collect debug data

Here is UI debug info when I plug Amanero before ODROID power up

http://pastebin.com/JhR9Ajg3Furthermore, from debug info, select ODROID Hifishield (I2S) seems weak up 7 pins I2S connector output,
If I can connect it to all I2S supported device, the option name ODROID DAC (I2S) may be better.
Best Regards
Michael
