So I have a Mk.1 player (serial 00366), and I downloaded the correct image for the player. I have exactly the same symptoms as described above, and my config.ini (/empeg/var/config.ini) does not contain an output section, let alone those two keys. :-(

I was previously running 1.02, and am now running 1.03. Attached are a partial log of the boot messages as well as my config.ini.
