Troubleshooting
Drivers are not installed correctly
Use the procedure described in Deleting the USB Audio Device driver (p. 14) to delete the USB Audio Device driver installed in your com-
puter, and install the UA-3 drivers once again as described in Connections and driver installation (Windows) (p. 8). 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.
A dialog box saying "Unknown Device found" appears, and I can't install the
driver
Depending on your computer, not all of the Windows 98 files required to support audio over USB may have been installed when the com-
puter was shipped.
Please check with the manufacturer of your computer.
Problems when using the UA-3
OS becomes unstable
• Starting up a computer when the UA-3 is already connected may cause the computer to become unstable.
If this occurs, start up the computer with the UA-3 disconnected, and then connect the UA-3.
No sound
• Is the UA-3's Recording input select switch set to "INPUT + GUITAR/MIC"?
When the Recording input select switch is set to "DIGITAL," the audio signals input to the digital Input connector are output. The
computer's audio data is not output.
• Is a digital device such as an MD connected to the digital output of the UA-3?
Depending on your application, playing audio with a digital device such as an MD connected to the digital output of the UA-3 may cause
a certain amount of time to be required for the digital audio output to be locked immediately after playback, so that there will be no sound
for one or two seconds. If this occurs, you can use the D-Out Smoother software from the included CD-ROM to make audio play
smoothly. For details, refer to Basic operation of the D-Out Smoother (p. 15).
• 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 using your computer's CD-ROM drive to play an
audio CD, or when playing background music for games with the UA-3 (p. 13).
• Are you running multiple applications?
If multiple applications are running simultaneously, an error message may appear. If this occurs, click [OK], and close the other applica-
tions.
Even if an application window is closed, it is still running if it remains in the taskbar, so be sure to quit any unneeded applications shown
in the taskbar.
• Have you specified the audio data output destination for OS?
The audio data output destination for a computer must be set to UA-3. For details on this setting, refer to Specifying the audio input/
output device (Windows p. 12) or Making the sound settings (Macintosh p. 18).
• Have you specified the audio data output destination for your playback software?
For some software such as Cool Edit Pro LE, you must set the audio data output destination as UA-3. 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 UA-3, the USB Audio Device driver must be installed. For details on installation and settings,
refer to Connections and driver installation (Windows p. 8, Macintosh p. 17).
• Are the various Volume Control faders raised?
Adjust the volume of each fader as described in Volume Control settings (Windows p. 12) or Making the sound settings (Macin-
tosh p. 18).
Sound is distorted
• Does the peak indicator light red?
If you are inputting sound from the line input jacks, use the Line input adjustment slider of the UA-3 to reduce the input level. If you
are inputting sound from the Guitar or Mic input jacks, use the Guitar/Mic input adjustment slider to reduce the input level. Also, the
number of LED's in the output level indicator will change according to the output level of the UA-3. If the red LED lights, use the line
output volume to lower the volume.
The volume level of the instrument connected to LINE IN is too low.
• Could you be using a connection cable that contains a resistor?
Use a connection cable that does not contain a resistor.
• Is the Line Input adjustment slider (p. 7) raised appropriately?
Noise is heard when playing back audio
• Is a mic still connected?
If a mic is connected to the UA-3, use the Guitar/Mic input adjustment slider to lower the input level.
