Whenever I add an AudioNode

Whenever I add an AudioNode like this, and try to run the program



AudioNode audio_run = new AudioNode(assetManager, “Sounds/run.wav”);



following error occures

why just adding the the node will cause any kind of problem?

It fails to load the file.

Check the path to your sound file.
