Important information
Windows 7 x64
DevilutionX 1.2.0 x64 downloaded from releases

Describe
As soon as the opening Blizzard video starts, there's a lot of crackling static.
In a game, if I just stay in town doing nothing, eventually the music will have some crackling too.
My CPU/HDD are almost idle during the issue.
If I run 1.1.0, the sound is perfect.

Expected behavior
Not have crackling sounds.

Additional context
I'm guessing it has to do with streaming the files instead of loading all of them into memory, which we already discussed. I did expect something like this with a very intense use of the disk or CPU, but not when they were almost idle.
