Humming or noise when playing music

Check the Soundtrack Player

1. Unplug all audio cables connected to the player.
2. Insert a pair of headphones into the front output, labeled with a (!).
3. If you hear the noise when playing through the headphones, try a different power output. 

Check the audio equipment

1. Check all of your cables are connected. Loose or damaged cables can cause a variety of noise problems.
2. Move your audio equipment to a different place. Humming and noise can be caused by interference from other electronics.
3. Plug all of your equipment into a single power outlet. This will eliminate ground loops, a common cause of humming.
4. Add a ground loop isolator, a device that sits between your audio equipment and the power outlet to help reduce noise.
