No sound (but with music)

[Luis]

Game runs without sound in Lubuntu (Ubuntu 15.04). In fact, running the game from console reports error in loading audio files.

I downloaded source and attempted to debug. After carefull analysis I surprised to find that the error comes from a 'for' loop located in file "src/audio.cc", function

void audio :: cargar_sonidos(void)

(which means "loading sounds")

... at line 144, where it reads

 for (i=0; i<12; i++)

For some reason the loop runs over i=11 when it shouldn't up to 12, leading to error later and so program does not use the sounds. Nowhere in the rest of the code the value of i is changed. The problem seems to be with the for loop itself and the way it is compiled. This suggests an error (potentially serious) with the g++ compiler.

I quick way to resolve this problem is to change line 144 to

for (i=0; i<12.0; i++)

... and after compilation, the sound now works.

I used Codeblocks to help compiling and testing.

EDIT:
I found the error in the source code.
In file src/audio.h in line 52,

Mix_Chunk *sonidos[11];

should be changed to

Mix_Chunk *sonidos[12];

Previously, in the for loop I described above the index of sonidos array goes out-of-bounds, though there is no report that this happens when running the program but instead it gives the unexpected behavior.
