Other applications running on your computer, especially CPU-intensive 
applications or applications that intercept or delay packets (such as 
firewalls), can cause broken audio.

Multiple Ethernet interfaces on a single PC can sometimes conflict with 
each other. For example, the IP Softphone 2050 sometimes exhibits 
intermittent breaks in audio when using docked notebooks that have a 
Xircom RealPort Cardbus Ethernet 10/100+Modem 56 PC Card 
(PCMCIA) inserted. In the specific case of this PC card, the problem 
relates to a version of the Xircom driver. This driver takes CPU cycles 
even when it is not active and this, in turn, causes IP Softphone 2050 
audio to become choppy. 

Solutions for this example are:

•

Upgrade your Xircom driver.

•

Remove the PC card when the notebook is docked.

To upgrade your Xircom driver: 

1. Download and install a new PC card driver from the Xircom web site. 

2. Follow the installation instructions provided by Xircom.
