I have to test for myself to see what's going on. What tool did you use to

Sorry, yes I noticed later on. Will email you a new one...

I think I found it. I should not do the mp3_play_init(). The box is normally
initialized for playback already, only after recording we have to do this
call. It resets the MAS. If you can compile rockbox, can you remove this one
and test it?

I'll pass on this, leave it to somebody else.
