Troubleshooting

COMMON
SYMPTOMS
Soundbar not
functioning properly.
WHAT YOU EXPERIENCE
Soundbar not detected or
synchronized.
POSSIBLE SOLUTIONS
1. Once the USB cable is plugged into the USB power
source, observe if the white LED light on the right
of the Soundbar lights up.
2. If the LED is not lit, check if the USB extension is
faulty. Replace the cable with a known good USB
cable, or directly insert the Soundbar USB cable
into the USB power source.
3. If the LED lights up after replacing the USB
extension cable, or by directly plugging the
Soundbar USB cable into the USB source, the first
USB cable is defective.
4. If no light is observed after replacing the USB
extension cable, or by directly plugging in the
Soundbar USB cable, then the Soundbar is
defective.
5. If LED is lit and the Soundbar does not function,
remove or unplug the Soundbar from the system
and re-start the computer.
6. Plug in the Soundbar again and check if the LED
lights up.
7. If the Soundbar still fails to connect, check if
Soundbar is present in Device Manager.
8. Swap the USB Soundbar to another USB port.
9. If the other USB port works, the first USB port may
be faulty.
If the other USB port does not work, proceed to the next
step.
1. Swap with a known-good USB Speaker or
device (e.g. keyboard) or connect the
Soundbar to another system.
2. If there is no other mouse or system available
to test with, use a known good USB keyboard
(or any other USB device) to see if it works on
the same USB port.
3. If the known good USB device is not working
on the same port, or the original Soundbar
works properly on another system, the former
system's USB I/O may be defective.
4. If known good USB device works, or the
Soundbar does not work properly on another
system, replace the Soundbar with a good one.
