Troubleshooting
The power of the device does not turn on.
• Make sure that the CI1 is properly con-
nected to the computer via a USB cable.
The USB bus-power is necessary to use the CI1.
• Confirm whether or not a proper USB ca-
ble is used.
If the USB cable is broken or damaged, have the
USB cable replaced with a known working one.
Use a USB cable no longer than 1.5 meters.
• Connect the CI1 to a computer without a
USB hub.
No sound.
• Make sure that the MASTER/PHONES/
MIX controls are set properly.
• Are your speaker cables connected properly?
Refer to “Connection Examples” on page 16.
• Are your speaker cables shorted?
• Are the volume controls of your sources,
audio devices, applications software,
computer operating system, etc., set at
appropriate levels?
• (Windows only) Is the output of your com-
puter operating system muted?
• Do you have several applications running
at the same time?
Be sure to quit all applications you are not using.
Noise occurs, or the sound is
intermittent or distorted.
• Is the PEAK indicator flashing red?
You might have to lower GAIN control level to
avoid distortion.
• Does your computer satisfy the system
requirements?
Refer to “System Requirements” on page 7.
• Is the buffer size setting of the Yamaha
Steinberg USB Driver set properly?
Refer to the “Setting the audio driver buffer size”

or USB devices (scanners, printers, etc.)
running at the same time?
Be sure to quit all applications you are not using.
• Are you playing back a large number of
audio tracks?
The number of tracks you can play at the same
time will depend on the performance of the com-
puter you are using. You may experience inter-
mittent playback if you exceed your computer's
capabilities.
• Are you recording or playing long continu-
ous sections of audio?
The audio data processing capabilities of your
computer will depend on a number of factors in-
cluding CPU speed and access to external de-
vices.

Disable the suspected network adaptor. Some
network adaptors can cause noise.
