I´ve searched, but anyone could help. It´s not inside game while playing. I put a sound cue in the game, but even if a don´t run, the sound continues to play repeatedly.
I´ve tried to set up in Editor Preferences > Miscellaneous > Unckeck “Enable Editor Sounds”.
A bit late to the party, but I have the same problem and it’s quite a nuisance. I’ve already grown utterly tired of hearing the song I used to test this on repeat.
