So im trying to make a boss, but for some strange reason after trying everything, the music and sounds i want to play will not play. Here is the code i have for it:

"sound_begin"
{
"1" "freak_fortress_2\asriel\asrielpre.mp3"
}
"sound_kspree"
{
"1" "freak_fortress_2\asriel\asrielkspe.wav"
}
"sound_win"
{
"1" "freak_fortress_2\asriel\asrielwin.mp3"
}
"sound_death"
{
"1" "freak_fortress_2\asriel\asrielloss.mp3"
}
"sound_fail"
{
"1" "freak_fortress_2\asriel\asrielloss.mp3"
}
"sound_ability"
{
"1" "freak_fortress_2\asriel\asrielpower.wav"
"2" "freak_fortress_2\asriel\asrieljump.wav"
"slot2" "1"
}
"sound_bgm"
{
"path1" "freak_fortress_2/asriel/asriel1.mp3"
"time1" "183"

}

I tried reversing the slashes, changing the paths, making the paths more specific but nothing is working!
