How to read OGG's from datafiles with AllegroOgg

Hi!

I'm a begginer who's trying to read OGG's from my datafile using AllegroOgg, but I can't do it

I'm using AllegroOgg because I can't compile AllOgg, and I only want to use OGG sound .

When reading from disk, I have no problem and it works 100% ok playing the sound:

install_sound (DIGI_AUTODETECT,MIDI_NONE,NULL);
char *data;  // OGG file in memory
int len;     // Length of file
FILE *f = NULL;  // file.ogg
5 
len  = (int)file_size("conv.ogg");
data = new char[len];
f = fopen("conv.ogg", "r");
fread(data, 1, len, f); 
ActFx = alogg_create_ogg_from_buffer(data, len);
11 
alogg_play_ex_ogg(ActFx, 65536, 255, 127, 1000, 0);
alogg_start_autopoll_ogg(ActFx, 25);
14 
15 
while( !keypressed() &&    alogg_is_playing_ogg(ActFx) )
{ rest(10); }
18 
alogg_destroy_ogg(ActFx)

But, when I try to read it from a datafile, I obtain no result:

  install_sound (DIGI_AUTODETECT,MIDI_NONE,NULL);
  DATAFILE *MyDataFile = load_datafile ("mydat.dat");
  ActFx = alogg_create_ogg_from_buffer (MyDataFile[conv].dat), 20786);
  alogg_play_ex_ogg(ActFx, 65536, 255, 127, 1000, 0);
  while( !keypressed() &&    alogg_is_playing_ogg(ActFx) )
  { rest(100); }
     
     alogg_destroy_ogg (ActFx);

20786 is the file lenght. If I check ActFx pointer after alogg_create_ogg_from_buffer is not NULL, and allog_play_ex_ogg returns ALLOG_OK, but nothing is played.

Can you help me? Thank you very much

EDITED:

I've still trying, and, finally, I've obtained the result wanted

I've forgot the alogg_start_autopoll_ogg(ActFx, 25); call.

I think I don't need to improve my PC's memory, but mine
::)
