Could two or more audio devices (such as the PC-80 and a mixer) be connected to
your computer?
Try connecting only the PC-80 by itself to your computer. See whether the noise disappears when just a single
PC-80 is connected. If multiple audio devices are connected to your computer, noise may occur in some
situations. If so, connect only the PC-80 to your computer.
Are you using a USB device in addition to the PC-80?
Try switching off USB audio devices other than the PC-80.
Are numerous software programs running?
Playback may be interrupted if numerous software programs are running at the same time, or when you start
up another software program. Close any unneeded software, and try again. If this does not solve the problem,
try restarting your computer.
Clicks or pops may occur in the sound if a LAN is operating.
Try disabling the LAN in the Device Manager. If this eliminates the clicks or pops, you may be able to solve the
problem by updating your LAN driver or BIOS.
Is the sample rate setting in your software the same as the PC-80’s sample rate setting?
Set your software and the PC-80 to the same sample rate.
If you switch the PC-80’s sample rate, you must turn the power of the PC-80 off, then on again to get the setting
to take effect.
Try adding memory.
Adding memory will improve the processing capability of your computer. For details on how to add memory,
refer to the owner’s manual of your computer.
Is the PC-80 connected to a USB hub?
Try connecting the PC-80 directly to the USB connector of your computer itself.
