Sound breaks up or there is noise.
The processing load on the computer causes sound to break up
and noise to occur.
Here are some methods to reduce the load on the computer.
1. A wireless LAN and software running in the background,
including antivirus software, regularly put processing
loads on the computer, which can cause sound to break up
and other noise. Stop wireless LAN transmission, antivirus
software and other software running in the background
when using this unit.
2. Set the buffer size (latency) in the audio application that
you are using or in this unit's Settings Panel to a larger value
(Windows only).
NOTE
Consult the maker of the audio application that you are
using for methods to reduce its load on your computer.
3. Change the settings of your computer so that they are
optimal for audio processing.
