Hi, play next sound into an array when the random sample returns the same of the previous play.
SOUND *sndArray[SOUND_COUNT];
...
int _i = random(SOUND_COUNT);
if(_i == my->skSound)
my->skSound = (_i + 1) % SOUND_COUNT;
else
my->skSound = _i;
ent_playsound(me, sndArray[my->skSound], 100);
Salud!

You are welcome  skSound is a local variable correct? Yes, a variable to save the index of the played sound at the end, local or not. Is each sound in that array a string? Nops. They are pointers to SOUND structs. How do you fill that sndArray with sounds? I use to build some helper functions by the array: create, destroy and functionality.
#define SND_METAL_COUNT 5
SOUND *sndMetal[SND_METAL_COUNT];
void sndMetalCreate () {
sndMetal[0] = snd_create("metald01.wav");
sndMetal[1] = snd_create("metald02.wav");
sndMetal[2] = snd_create("metald03.wav");
sndMetal[3] = snd_create("metald04.wav");
sndMetal[4] = snd_create("metald05.wav");
}
void sndMetalRemove () {
int _i = 0;
for (; _i<SND_METAL_COUNT; _i+=1)
snd_remove(sndMetal[_i]);
}
SOUND *sndMetalRandom () {
static int _indexOld = 0;
int _i = random(SND_METAL_COUNT - 1);
if (_i >= _indexOld)
_i += 1;
_indexOld = _i;
return sndMetalArray[_i];
}
...
sndMetalCreate ();
...
ent_playsound(me, sndMetalRandom(), 100);
...
sndMetalRemove ();
Salud!

yes but keep in mind that this might cause stuttering while the file is being loaded.
usually you create a sound once and keep it (a more sophisticated approach would be only loading sounds in areas of the game where they are needed)
I'm also sure that txesmi's example was meant that way.
when setting up your application you call sndMetalCreate() to create all the sounds needed and you then can play them as much as you want.
once you don't need the sounds anymore (like closing your application) you call sndMetalRemove() to remove those sounds again.
