Troubleshooting
Digitally recorded sound is distorted, pitch changes or contains noise
• If you are using a long digital cable, noise may occur or the sound may be distorted when it is connected. Use digital cables that
are one meter (about a yard) or shorter.
• Does the sampling frequency setting in the application match the sampling frequency of the digital device connected to the digital
input connector?
• When using digital recording, it is not possible to record in monaural. Set your recording software to the "stereo" setting.
Noise is present in the recorded sound
• It has been found that noise tends to be introduced in sound recorded on the iMac series models, which were released after the
summer of 2000.
• In the SimpleSound application that is included with MacOS, noise will be heard in the sound if it is played back immediately
after being digitally recorded. Save the sound first, then try playing it back.
• Update the USB Audio driver to 1.0.5f4.
If the USB Audio driver, which is provided with the Mac OS, is under 1.0.4, update it to 1.0.5f4.
You can download the driver from the URL below:
http://asu.info.apple.com/swupdates.nsf/artnum/n11703
Checking the USB audio driver's version
1. Connect the UA-3 to the computer.
2. From the Apple menu, select [Apple System Profiler].
3. Click the [Devices and Volumes] tab.
4. In the USB section, the screen will indicate "Audio (UA-3 USB Audio Device)." Click the arrow at the left of this text.
5. The number displayed to the right of "Driver version" is the version of the USB audio driver.
A blank (silent) file is created when you record
• Try setting the bit rate to "16bit."
If you are using Windows98 Second Edition, and your recording software is set to a bit rate of 8 bits, a blank file may be created, so that
you may not be able to record effectively. If this occurs, you will be able to record correctly by setting the bit rate to "16 bit".
• Data that contains the SCMS flag cannot be recorded digitally.
The UA-3 supports SCMS (p. 5), so that if SCMS-flagged data (such as data from an MD that was digitally copied from a commercial
music CD) is input to the digital connector, the UA-3 will not be able to record this on the computer. (The sound will be output from the
line output jacks and the headphone jack.)
Cannot record digitally
• Is the Recording input select switch set to "DIGITAL"?
• Is the application set to the same sampling frequency as that of the digital device connected to the digital input connector?
• Recording will no longer be possible if you switch the sampling frequency (for example, between digital broadcast A mode and B
mode) of a device while it remains connected to the digital input connectors.
When switching the sampling frequency, you need to disconnect, then reconnect the digital cable.
• It is not possible to record digital data of a format other than consumer digital audio device format.
Cannot Record Music CD
• The UA-3 cannot record music CDs in the computer's CD-ROM drive with CoolEdit Pro LE or other programs.
To record music CDs in the computer's CD-ROM drive, you need to first select your computer's sound card as the audio device (Wave-
form Record) that is to be used for recording by CoolEdit Pro LE (or the application you are using), then you can proceed with recording.
When recording a music CD with a sound card, uncheck "Enable digital CD audio for this CD-ROM device" you checked in 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).
The volume changed when you resumed from Suspend or Hibernation status
• When Windows 2000 resumes from Suspend or Hibernation, the output volume setting is changed due to a problem of Windows.
Start up the Mixer application as described in Volume Control settings (p. 12), and adjust the USB Audio (Speaker) slider.
Game background music does not sound
• Does the game use an audio CD for background music?
If an audio CD is used to provide background music for the game, 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).
Problems common to software in general
Can't install
• Is the included CD-ROM inserted into the CD-ROM drive of your computer?
• During installation, were the CD-ROM drive name and the installation file name input correctly?
• Is there sufficient space on your hard disk?
