Solution

cable.
If a USB hub is used in the connection, check if the
hub is functioning properly. Alternatively, change the
connected port.
Set the PC properly.
The audio may be interrupted if the PC is used for an
operation that imposes a burden on the CPU during
the audio output. Avoid executing operations that may
impose a burden on the CPU.
The audio may be interrupted if a USB cable is connected
to or disconnected from another USB connector of the
PC. Do not connect or disconnect the USB cables to
other equipment during audio playback.
Noise may be noticeable if the system is installed near

system away from a source of strong magnetic waves.

tion cord was unplugged while the system was turned on.
