I think it might be linked to sfml library.
paul@rafulos:~$ apt list --installed |grep sfml

WARNING: apt does not have a stable CLI interface. Use with caution in scripts.

Did:
paul@rafulos:~$ sudo apt install libsfml-audio

But it did not fixed the problem.

The file is part of FreeDink...
https://github.com/gitGNU/gnu_freedink/blob/master/src/sfx.cpp
Sound effects (not music) management

More precisely:
/**
 * Free chunk once it's played (through Mix_ChannelFinished()
 * callback)
 */
static void CleanupChannel(int channel)
{
  /* SDL_mixer won't try to free the actual audio buffer (fake_buf) if
     the Chunk was loaded via Mix_QuickLoad_RAW() - which is a good
     thing since fake_buf is shared by all Chunks. We still need to
     free the Chunk when it's done playing. */
  Mix_Chunk *chunk = Mix_GetChunk(channel);
  if (chunk == NULL)
    {
      log_fatal("Internal error: cannot free channel %d's chunk (where did it disappear?)", channel);
      exit(1);
    }
  Mix_FreeChunk(chunk);
  channelinfo[channel].finished = 0;
  channelinfo[channel].looping = 0;
  channelinfo[channel].cur_sound = -1;

  /* Revert SetVolume and SetPan effects */
  Mix_UnregisterAllEffects(channel);
  Mix_Volume(channel, MIX_MAX_VOLUME);
}

Latest seems: http://ftp.gnu.org/gnu/freedink/freedink-109.6.tar.gz in 2019.
So it seems to be latest version.
