According to the Widelands thread, he custom compiled a libSDL_mixer1.2.8 and you had to install that to make it work.

I installed it on my n810 and it didnt help, though I didnt expect it to because I compiled with 1.2.6.

Problem is I can not find 1.2.8-1 to install in scratchbox I can only find 1.2.8-5 and it has SOOOOO many dependency issues with things I am concerned about upgrading because then nothing I compile may work on the tablets anymore.

Oh well, I will keep looking and plugging away at it.
