Thanks a lot!

Copied the .so files from my kindle to the arm gcc library path and recompiled. It didn't work again, same error all along.

If I tweak the sliders on alsamixer I hear white noise when mpg123 starts and I don't when I stop it, so it is somehow communicating with the sound hw.

And lastly, if I run mpg123 and try to use the builtin player, it does not work, so probably the hardware is in use.
