I think it is a little bit strange that you don´t mention that Max2Play HiFiBerry Image don´t work with Raspberry Pi 3.
The download page say that it works with Raspberry Pi all. I have spent hours to get it work, without succeeding.
I have the same problem.
m2p_hifiberry_226_wps.img don´t start up on Raspberry Pi3.
m2p_Jessie_wps_229.img works better but I am not able to activate the recently bought license.
I will try it again today to see if I have a better luck.
