SMBX Problem with Musics/Sounds

[Jarckius]

I have a problem with SMBX since I bought my new PC. SMBX doesn't seem to work normally, now because of some strange reason all the musics and sounds just stop playing. For example, I open SMBX, everything well, I play a level, and the music plays nothing out of the ordinary, but after I enter another section the music just stops playing. Other sounds still play, but not every sound. In the next section with the same music, the music plays, but with less sounds. No matter how many times I close and run SMBX again and open the same level the problem is still there. And when I click "Start Game" musics and sounds doesn't play at all, only the intro music.

I've tried million of things to solve this problem, I've actualized my sound drivers, I formatted my PC 3 times with different Windows; 7Ultimate/8/8.1. Some people told me the problem was SMBX, the one I've downloaded, but all versions, 1.2/1.3/1.3.0.1 do the same on my PC. The only program that has this strange problem is SMBX, any other program works just fine. I've tried SMBX on another PC that I have and it works fine. Please help.

This just happens sometimes, it's probably some kind of bug caused by one's system (I've experienced this as well). I doubt there's anything you can do about it, sorry.

This often happens when the level/episode uses custom player graphics, I've noticed.

To fix that, make your custom playables replace the defaults in the game's "graphics" folder.
