I'm using SFML 2.3 to play an ogg file. I'm a novice to C++. Not sure what's causing it. This is the code I'm using to play the ogg sound.Thanks in advanced. sf::Music music; music.openFromFile("Forest_v3.ogg"); return -1; music.play();

Edit : I've attempted pasting all the DLLs from SFML/bin into my source files folder but no changes. I've also referenced the sfml-audio-d.lib file but no changes. The errors remain.

I do not think you setup your IDE properly. If using visual studio, you need to do the following:

Go to your SFML folder >> bin. Then, copy & paste all those DLL's into the same folder as your source files.
Then go to Project>>Properties>>Linker>>Input>>Additional Dependencies: and make sure that you have "sfml-audio-d.lib" in there. (While using debug)

Edit: Actually, the missing DLL's in the same directory would cause an error dialog box to appear, but not the exception you are having. Are you running in release? Go to Build>>Configuration Manager, and it should say "Debug" under "Active Solution Configuration", as well as under "Configuration".

Update me on your status and I will do the same for my answer.

Yeah - I was running it in release. Setting it to debug hasn't changed.
