To test it (r823) I got some .wav sound files of a .mix file that I made time ago and I converted them into IMA ADPCM format as suggested (with XCC mixer) and dropped directly in the game folder (it should be the same as dropped in a mix file), now those sounds are only noise ingame but those converted sounds can be reproduced in any audio player.
