Troubleshooting
Noise is heard when playing back audio
• The graphic accelerator of your computer may cause noise to occur
during audio playback.
Use the following procedure to set graphic acceleration to "None."
1.
In the Windows Control Panel, double-click [Display] to open the
Display Properties dialog box, and click the [Settings] tab.
2.
Click [Advanced] to open properties, and click the [Performance] tab.
3.
In Graphics, move the Hardware acceleration: slider to None, and click
[OK].
4.
In the Display Properties dialog box, click [OK] to close the dialog box.
Then restart your computer.
• Noise may be heard if you record and play back simultaneously.
If you record and play back simultaneously, the playback may be interrupted
depending on the performance of the system, and this may be heard as noise.
However since priority is given to recording, the recorded data will not be
lost.
• This problem may be solved by properly grounding the chassis of
your computer, or the ground prong of the plug on the AC power
cord that was supplied with your computer. Also, make sure that
there are no devices nearby that emit a strong magnetic field,
such as a television or a microwave oven.
• Are a large number of audio devices connected?
If a large number of audio devices are connected, noise may occur. Do not
connect audio devices that you are not using.
Sound is interrupted during audio playback
• Try increasing the memory
You can increase the processing power of your computer by adding more
memory. For details on adding memory, refer to the owner's manual for your
computer.
• Does your computer fulfill the USB specifications?
The audio may be interrupted if you are using a computer that does not
electrically meet the USB specifications. In this case, the problem may be
solved if you connect a USB hub that contains its own power supply.
• Are numerous applications running?
If you use numerous applications during playback, or start up another
application, the playback may be interrupted depending on your computer
system. Exit all unneeded applications, and try again. If this does not solve the
problem, try restarting a computer.
