When I try to use Mix_VolumeMusic on mp3 files everithing goes ok.
When I replace mp3 with a “midi+sample” music file (ex. .it or .xm)
I obtain no effect.
You can try by yourself with this small program and the "music.it"
file included in SDL “aliens” demo.
and you’ll see that modifing the Mix_VolumeMusic value doesn’t
change the result.
I don’t think it’s my fault 'cause it works with mp3 music.
Thanks,
Enzo.

Mix_Volume’s prototype is:
int Mix_Volume(int channel, int volume)
Even if you do Mix_Volume(-1, MIX_MAX_VOLUME/4);
the music will still be full volume.
Mix_VolumeChunk’s prototype is:
int Mix_VolumeChunk(Mix_Chunk *chunk, int volume)
and Mix_LoadMUS(“filename.wav”) returns a Mix_music *, not a Mix_Chunk.
but Mix_music is a structure with pointers to (like Mix_music->wave or Mix_music->mp3, depending on what Mix_music->type is…), that we may be able to use…
But that isn’t the point, if it is just a matter of manually going to the root of the data source and setting the volume, why not just set it via the Mix_VolumeMusic command with the code there?
Should it have worked before, and this is just a bug that cropped in?

Have u tried using Mix_Chunk instead of Mix_Music. The following taken from
SDL_mixer.h indicates the use of Mix_LoadWAV() or Mix_LoadWAV_RW() for the
type of data your describing. Line 115 indicates that Mix_LoadWAV() is
essentially the same as Mix_LoadWAV_RW only with a couple extra parameters
ie “rb” and 1 thus Mix_LoadWAV() should be enough. Change the volume via
Mix_VolumeChunk() or directly from the Mix_Chunk struct eg
Mix_Chunk *chunk;
chunk->volume = 100;

Hi Enzo,
I ran into the same problem, and since at the time my internet service
was down, I dug into it and fixed it my self. Although you got many
responses about Mix_Volume and Mix_VolumeChunk, these don’t seem to
have anything to do with the tracker style music playback (as you
noted, mp3 volume control works perfectly).
The problem seems to be in MikMod. As far as I could tell, MikMod
is overriding the volume you request with the volume encoded into the
song for each note of the track. Here is my patch, which scales
sample to the volume you request after all the volume effects from the
track have been applied:
tmpvol/=128;
/* fade out */
if (pf->sngpos>=pf->numpos) tmpvol=0;
Hope that helps,

I’m working on it now. I’ll test it and add it to the next SDL_mixer release.

No, I was just lazy and didn’t implement it. It’s just a matter of changing
the memcpy to SDL_MixAudio().
