[AD] Sound problem!

[Martin Dušek <dusekm@xxxxxxxxxx>]

I have some problems with playing *.mod (and *.s3m) files with allegro 3.9.39 and jgmod 0.99 (the latest). I´m using the debug version of jgmod library (Bob told me that there is a msvc release linker bug).
If I used DIGI_AUTODETECT the music is not play correctly (I don´t hear the bass channell).
I use this:

 

bool sound_init()
{
 reserve_voices (16, -1);
 if (install_sound(DIGI_AUTODETECT, MIDI_NONE, NULL)) {
  allegro_message("Error initialising sound system\n%s\n", allegro_error);
  return 1;
 }
 if (install_mod (8) < 0) {
  allegro_message("Error setting digi voices\n");
  return 1;
 }
 set_mod_volume (128);
 song = load_mod("snd/song.s3m");
 if (!song) {
  allegro_message("Error loading snd/song.s3m\n");
  return 1;
 }
 is_sound = true;
 return 0;
}

If I use DIGI_AUTODETECT (it used primary sound device with direct mixing) - debug messages:
- some dlls loaded -
DirectSound interface successfully created.
DirectSound cooperation level set to PRIORITY.
DirectSound caps: 16 bits, stereo, 44100Hz
primary format:

44100 Hz

If I use DIGI_DIRECTAMX(0) it is played correctly:
DirectSound interface successfully created
DirectSound cooperation level set to DSSCL_WRITEPRIMARY
DirectSound caps: 16 bits, stereo, 44100Hz
primary format:

It looks like Allegro bug probably!
