Troubleshooting

Can’t install/uninstall the driver

• Did you log onto Windows as a user with administrative privileges?

In order to install/uninstall/re-install the MA-1EX driver in Windows, you must log onto Windows as a
user with administrative privileges, such as Administrator.

You are asked for the driver file even though you installed the driver

• Did you connect the MA-1EX to a different USB connector than the one you used when installing
the driver?

If your computer or USB hub has two or more USB connectors, and you connect the MA-1EX to a USB
connector to which you have not previously connected it, this dialog box may appear even though you
have already installed the driver.
Install the drivers once again as described in
“Getting Connected and Installing Drivers English”
(p. 6).
This is not a malfunction.

The MA-1EX Driver Is Not Installed Correctly.

Use the procedure described in

“Deleting the USB Audio Device driver”

(p. 29) to delete the USB Audio
Device driver installed in your computer, and install the drivers once again as described in
“Getting
Connected and Installing Drivers English”
(p. 6).
Check whether there is an item named
“Unknown Device”
in
“Other devices”
or in
“Universal Serial
Bus controllers.”
If you find
“Unknown Device,”
delete it.

Problems when using the MA-1EX

OS becomes unstable

• Starting up a computer when the MA-1EX is already connected may cause the computer to become
unstable.
If this occurs, start up the computer with the MA-1EX disconnected, and then connect the MA-1EX. On a
computer that uses a USB keyboard, starting up the computer with the MA-1EX already connected may
cause operation to become unstable. In this case, start up the computer with the MA-1EX disconnected,
and then connect the MA-1EX.

No sound

• Are you attempting to use the CD player of your computer to play an audio CD?

If you wish to play an audio CD on the CD-ROM drive of your computer, refer to

“When playing audio
CDs from the computer’s internal CD-ROM drive, or using the MA-1EX to play game music”

(p. 12).

• Are you running multiple software?

If multiple software are running simultaneously, an error message may appear. If this occurs, click

[OK]

,
and close the other software. Even if a software window is closed, it is still running if it remains in the
taskbar, so be sure to quit any unneeded software shown in the taskbar.

• Have you specified the audio data output destination for your operating system?

You must specify the

USB Audio

as the audio data output destination for your computer.

• Have you specified the audio data output destination for your playback software?

For some software, you must set the audio data output destination as

USB Audio

. For details on this
setting, refer to the owner’s manual for the software.

• Have the drivers been installed correctly?

In order to playback audio data using the MA-1EX, the

USB Audio Device driver

must be installed. For
details on installation and settings, refer to

“Getting Connected and Installing Drivers English”

(p. 6).

• Are the faders of the Volume Control raised?

Adjust the volume of each fader as described in

“Volume Control setting”

(p. 11).
