8 Installation fails.
Installation completes, but the computer does not
recognize the unit.
If some trouble is causing installation to fail, or if the
computer does not recognize the unit even though
installation completes, check the following.
1. Change the USB port
Since the unit might not properly function with
some USB ports, try connecting to a different USB
port (that is built into the computer), and reinstall
the driver.
NOTE
•
Try again after disconnecting other USB devices.
(Keyboards and mice can be left connected.)
•
Do not use a USB hub. Always connect the unit
directly to a USB port on the computer (built-in)
2. Stop software that is running in the background
Since antivirus software and other software
running in the background can interfere with
installation, stop them before beginning instal-
lation.
See "Installing the driver" in this manual for how
to install and uninstall the driver.
8 There is no sound even when audio is
playing back.
The audio output must be set on the computer.

See the "Windows 8" or "Windows 7" instructions
in the "Windows Media Player" section of "8 –

ences..." from the Apple menu.

3. On the Output tab, select "US-2x2" or "US-4x4".
After completing the setting, restart the
computer and check the sound of playback.
Depending on the application that you are
using, you might need to make additional device
settings.
In particular, DAW software operates using audio
engines with settings that are different from the
OS settings, so confirm the DAW driver settings
first after installing the software for this unit.
Please see the manuals for the applications that
you are using for detailed setting procedures.
8 Sound breaks up or there is noise.
The processing load on the computer causes sound
to break up and noise to occur.
Here are some methods to reduce the load on the
computer.
1. A wireless LAN and software running in the
background, including antivirus software,
regularly put processing loads on the computer,
which can cause sound to break up and other
noise.
Stop wireless LAN transmission, antivirus
software and other software running in the
background when using this unit.
2. Set the buffer size (latency) in the audio appli-
cation that you are using or in this unit's Settings
Panel to a larger value.
NOTE
Consult the maker of the audio application that
you are using for methods to reduce its load on
your computer.
3. Change the settings of your computer so that
they are optimal for audio processing.

1. In Windows 8, right-click the ordinary start
screen (Metro user interface screen) and then
