Audio Tuning and Sound Card Information
This section includes the following topics:
Achieving Optimal Tuning While Using the Audio Tuning Wizard
You can tune Cisco IP Communicator output volume by using two controls in the Audio Tuning Wizard:
•A master volume slider—Affects all applications
•A wave volume slider— Affects most applications, including Cisco IP Communicator
Common Tuning Mistakes
Users often set the volume levels high initially from the master or wave sliders in the Audio Tuning Wizard, and later reduce the levels by using Microsoft Windows volume controls or laptop sound keys because other applications sound too loud. When they subsequently discover that Cisco IP Communicator sounds too soft, users employ the volume button on the main Cisco IP Communicator interface to sharply increase the call volume.
You should be aware that a high volume setting in the application can cause users' voices to sound distorted.
Recommended Tuning Guidelines
Follow these guidelines to use the Audio Tuning Wizard dialog box to adjust the volume levels for Cisco IP Communicator:
•Adjust the master volume slider first. Because this setting affects all applications that play sound, test the setting against other applications (such as Microsoft Windows Media Player and RealPlayer) to ensure that volume levels are appropriate.
•Adjust the wave volume slider to a comfortable level for phone calls after adjusting the master volume.
•If the user changes volume settings from Microsoft Windows, run the Audio Tuning Wizard again (according the above guidelines) to re-tune the master and wave volume settings.
Bluetooth Devices, Jittery Audio, and Latency Optimization
Various sound cards have differing capabilities. Some are good for low latency audio, which is required for telephone calls, while others (including common Bluetooth devices) cannot be used in very low latency modes. The resulting audio sounds consistently jittery, with frequent pops and clicks.
Testing for Latency Optimization
To test which latency setting is best for your particular set of audio devices (USB headsets, USB handsets, or sound cards), follow this procedure to modify audio parameters for Cisco IP Communicator.
Note We recommended that you test the .reg file with the lowest settings first and continue to the next .reg file, if needed. However, a Bluetooth audio device with Widcomm PC drivers requires settings that are not lower than those in the HighDelay.reg or VeryHighDelay.reg file.
Use this procedure if you are having difficulty with an audio device that sounds less than satisfactory with Cisco IP Communicator, but performs well with other applications.
Step 1 In the Cisco IP Communicator program folder, double-click one of the following .reg files:
•LowDelay.reg (Lowest latency, default setting)
•VeryHighDelay.reg (Highest Latency)
Step 2 When prompted, confirm that you wish to import the settings into your Microsoft Windows registry.
Step 3 Make a test phone call and verify that the audio sounds good to you and to the other party. If you hear distortion, audio dropouts, or robotic sound, proceed to the next file on the list and repeat the previous steps.
About Choosing Headsets and Handsets for Cisco IP Communicator
Even though internal testing of third-party headsets and handsets for IP Communicator has been performed, Cisco does not certify or support products from headset and handset vendors. Because of the inherent environmental and hardware inconsistencies in the locations in which IP Communicator is deployed, there is no one best solution that is optimal for all environments. Cisco recommends that customers test the headsets and handsets that work best in their environment before deploying a large number of units in their network.
The primary reason that support of a headset or handset would be inappropriate for an installation is the potential for an audible hum - either a hum heard by the remote party or by both the remote party and the IP Communicator user. Causes for the hum range from electrical lights near the PC to the PC power source itself. In some cases, a hum experienced by a user plugged directly into the PC USB port may be reduced or eliminated by using a powered USB hub.
In some instances, the mechanics or electronics of various headsets can cause remote parties to hear their own voices echo back when they speak to IP Communicator users. The IP Communicator user will not be aware of the echo.
Finally, some analog headsets do not match the electrical characteristics for which some soundcards are designed. The microphones on such headsets are frequently too sensitive, even when the input levels in IP Communicator are reduced to their lowest values; the users of such headsets will sound distorted to remote parties.
It is important to ask IP Communicator users whether a particular headset sounds good to them. In addition, remote parties should be queried as to the reception from IP Communicator when using a particular headset.
Testing performed in the Cisco labs has shown that the Plantronics DSP 300 and Plantronics DSP 400 have performed well with IP Communicator, but it remains the customer's responsibility to test in their environment.

Virtual Private Network (VPN)
There are some known issues when using Cisco IP Communicator Release 1.1(3) with VPN software.
Problem Description (CSCee09266)
One-way audio is observed when using Cisco IP Communicator with VSClient VPN software
Refer to CSCee09266 for more information.
Problem Description (CSCed21257)
When using Cisco IP Communicator over a dialup (modem) connection using the Cisco VPN client and audio is poor, Cisco IP Communicator unregisters from Cisco CallManager spontaneously, and sometimes the VPN connection spontaneously drops.
Workaround: None. Dialup connections have insufficient bandwidth to support Cisco IP Communicator over Cisco VPN.
Refer to CSCed21257 for more information.
Universal Serial Bus (USB) Audio Devices)
There are some known issues when using Cisco IP Communicator Release 1.1(3) with USB audio devices.
Problem Description (CSCec58049)
When using a VXi-brand headset connected to the PC via a VXi TuffSet USB adapter, the other person(s) in the call may hear their own speech echo.
Workaround: Some VXi headsets are prone to acoustically-coupled echo. The microphone in the headset picks up the output of the earpiece(s) and feeds it back to the remote party. To reduce the echo, use the Audio Tuning Wizard to reduce the microphone volume as much as possible. This will reduce the amount of acoustic feedback and help reduce echo. Likewise, lower the headset speaker volume as much as possible. Finally, consider configuring the headset in Cisco IP Communicator for speakerphone mode rather than headset mode. Although this will reduce the frequency response of the headset (the sound won't be as rich), it will suppress some of the echo.
Refer to CSCec58049 for more information.
Problem Description (CSCec63499)
An audible hum is heard on the headsets speaker or handsets receiver when directly connected to some laptop USB ports.
Workaround: Use a powered USB hub.
Refer to CSCec63499 for more information.
Problem Description (CSCec23649)
Digits are dialed twice when using the Claritel i750 USB Handset.
Workaround: Enter the digits before pressing the On-Off button or before going off-hook, or quit the Claritel Application Gateway application (running in the system tray) and remove it from the startup items. This will allow normal dialing with the handset and Cisco IP Communicator, but may interfere with other applications that use the handset (if any).
Refer to CSCec23649 for more information.
Problem Description (CSCin50824)
Some buttons and keys do not function when using a supported USB handset device configured for handset mode.
Refer to CSCin50824 for more information.
Cisco VT Advantage
There are some known issues when using Cisco IP Communicator Release 1.1(3) with Cisco VT Advantage.
Problem Description (CSCee00053)
When changing a USB handset or headset, the user receives the following error message: "Audio Tunning Wizard cannot configure this device to play sound. Cisco IP Communicator may not function properly with this device."
Workaround: Reboot the PC and insert the USB device for Cisco IP Communicator followed by the USB device for Cisco VT Advantage.
Refer to CSCee00053 for more information.
Problem Description (CSCee07575)
When using a USB Audio Device with Cisco IP Communicator at the same time as Cisco VT Advantage, user receives the following error message: "USB Controller Bandwidth Exceeded."
Workaround: Avoid using Cisco VT Advantage and a USB Audio Device with Cisco IP Communicator at the same time. Another workaround is to ensure that the the Cisco VT Advantage camera and the USB Audio Device for Cisco IP Communicator are using separate USB ports on the PC.
Refer to CSCee07575 for more information.
