Wii, SDL_mixer, ogg = not working

Post by richi902 » Mon Oct 31, 2011 3:24 pm

hi,

i have a problem with sdl_mixer and ogg playback on the wii with devkitpro.
all i get is just garbage out of the speakers, i already tried rencodeing the ogg's to 48Hz(from 44) but nothing changed. i also recompiled sdl_mixer myself from sources.

on windows and on the xbox i have no problem at all, play's fine at any Hz.

contents of the make file from SDL_mixer(wii)

Code: Select all

Change line 106 in SDL_mixer/src/load_ogg.c from:

Code: Select all

spec->format = AUDIO_S16;
to:

Code: Select all

spec->format = AUDIO_S16MSB;
or technically, for cross platform compatibility it should be this:

Code: Select all

spec->format = AUDIO_S16SYS;
