Humming, buzzing or rattling noise heard from product | Companion® 5 multimedia speaker system
If you hear an unexpected noise from your product:
Try the following:
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.
Try connecting a different audio device.
If available, connect another audio device using the same cables and connections to determine if the issue is related to the first device or its settings.
Reset your product.
Much like rebooting a smartphone, your product might need to be reset on occasion to correct minor issues. For more information, see Resetting your product.
Try connecting to a different computer.
Differences among computer hardware and software can present issues with different USB devices. Try connecting your product to a different computer (a different brand computer, if available), then try again. If the issue is resolved, it is related to the first computer.
Connect the computer to the control pod input.
If there is a problem with the USB output on the computer, use the 3.5 mm audio output instead. Using a 3.5mm male-to-male AUX cable, connect one end to the output on the computer and the other end to the control pod input.
