Humming, buzzing or rattling noise heard from product | Wave® music system IV
When does the issue occur?
When playing a disc on the built-in disc player
Determine if the noise is occurring during playback of the last track on the disc.
During playback, the system is continuously loading the data being read off the disc and storing it into a playback buffer. This buffer prevents audio interruptions during playback. When the disc reading mechanism has finished buffering the data of the last track, the mechanism returns to its home position. If the audio at the end of the last track is very quiet or the volume of the system is very low, the movement of the disc mechanism may be heard.
Make sure there are no obstructions on the disc, like an attached label.
Labels could prevent a disc from spinning properly (i.e. if the label is dettaching or making contact somewhere in the systems.) Try another disc without a label.
Try a different disc.
Check if other discs play in your system to determine if the issue is related to one or certain discs or disc types.
Any time during normal use
Be sure the rattling noise is not something on or near the system.
A loose item on or near the system may be vibrating when certain frequencies or volume levels are played. Secure any loose items or move the system or items to another location if the system sound is causing nearby items to rattle.
