that 3Com recommends that you use your system's USB audio capabilities
rather than using sound card audio.
Choppy audio occurs during telephone conversations or during the audio
test in the Configuration Wizard, or there are delays in audio playback
during telephone conversations.
Description
This problem is caused by incompatible audio buffer size settings.
Solution
Audio buffer size settings are expressed as two values: Delay and
Multiplier. The product of these numbers represents the overall size of the
buffer pool. Lower values for these numbers reduce echo delay. Higher
values increase audio quality. Change these values in any of these ways:
Select Configuration Wizard > Audio > Audio Configuration
■
Select Configuration Wizard > Mic > Audio Configuration
■
Select Options > Advanced
■
These numbers depend on your computer hardware and operating
system. Experiment with different value combinations to see how low you
can adjust the product of the delay and multiplier and still achieve good
audio quality.
