The "play sounds" option is always disabled on Windows 7 and 8.1. The reason for the app crash that is now solved (file does not start with RIFF, and issue #1521) was caused due that the OGG-format sound files are very problematic on Windows 7 and 8.1 systems.

The solution for this is replacing the OGG sound files with WAVE-format sound files which still have the .ogg extension while the internal format is WAVE, this brings way better OS support for 7/8.1 and then the app not only will not gonna crash, but sounds will work fine

"As a workaround until this issue is fixed, replace the "sounds" folder inside the main BEE folder with the one from this archive:
