Hi There, Today I was working on the new examples for the Panda.js Fiddler and noticed a small bug in the audio module. setMusicVolume: function(value) { if (!game.Audio.enabled) return false; this.musicVolume = value; if (!this.currentMusic) return false; if (this.context) { this.currentMusic.gainNode.gain.value = this.musicVolume; //ERROR! } else { this.currentMusic.volume = this.musicVolume; } return true; },this.currentMusic.gainNode.gain.value = this.musicVolume; should be: this.audioObjects[this.currentMusic].gainNode.gain.value = this.musicVolume; @Enpu: Which way do you prefer to receive bugreports? (I have little experience with github yet so that's why I post this bug over here ). Stephan
