Test the Microphone in Sound Recorder
- Click "Start," > "Programs" ("All Programs" for Windows XP) > "Accessories" > "Entertainment" > "Sound Recorder."
- Click the Record button and speak into the microphone of the
camera. You should see the green line move, indicating the application
is picking up sound.
- Click the Stop button.
- Click the Play button. If there is no sound at playback, check to make sure the correct device is selected.
- Click "Edit," then "Audio Properties."
- Make sure Logitech is listed as the Preferred device for "Sound recording."

While using MSN Messenger it is the messenger program, not the
camera software, that negotiates the audio streams between two MSN
Messenger Clients. Although we cannot directly support audio issues in
MSN Messenger, the following steps have been known to resolve and
improve audio issues in MSN Messenger. For further information, please
consult the help documents associated with MSN Messenger.
Test Your Networking Router
You can also test to see if your router is causing audio
issues by either physically bypassing your router and connecting
directly to your cable/DSL modem or by setting up your computer as the
DMZ (de-militarized zone). If you are a novice networking user, it is
not recommended that you leave your computer in the DMZ state for
extended period as that may leave your computer vulnerable to attack.
However, you may briefly configure your computer as the DMZ to
determine if your network settings are causing the audio issues. For
DMZ setup instructions, please consult your router's documentation.
Enable Universal Plug and Play (UPnP) on both Windows XP and Your Router.
If either of the above steps resolves the no audio problem, try the following steps.
-
Open Add or Remove Programs in Control Panel. To open Add or Remove Programs, click Start, point to Settings, click Control Panel, and then double-click Add or Remove Programs.
-
Click Add/Remove Windows Components.
-
In the Components list, select the Networking Services check box, and then click Details.
-
Make sure the Universal Plug and Play box is checked.
Notes: If you used a CD to set up Windows, you will be prompted to insert it into your computer.
If your router does not support UPnP or you still get no audio after
enabling UPnP on both Windows XP and your router, you must manually
open all UDP ports between 5004 and 65535. This is because the audio
streams are sent dynamically using that range of ports. Without a
dynamic way to open those ports like UPnP, there is no way for MSN
Messenger to successfully negotiate the audio stream. Consult your
router's documentation for instructions to manually open these required
ports.
If you are still experiencing audio issues within MSN Messenger, and
you have verified that the microphone is working in Sound Recorder,

This article covers Accoustic Echo Canncellation (AEC) and how it works.
Answer
This article applies to the following products:
QuickCam 10.x and RightSound supported cameras
QuickCam 11.x and RightSound supported cameras
Call Central and RightSound support audio devices
This article applies to the following platforms:
Windows® 2000 Professional
Windows® XP Professional
Windows® XP Home
Windows® Media Center Home
Windows® Vista
Accoustic EchoCancellation (AEC)'s purpose is to prevent sounds from
your computer's speakers to be picked up by your microphone. This can
be a significant problem with audio or video calling applications where
the voices or sounds from other parties of the call is being
inadvertently picked up by the microphone and fed back into the call,
creating echo and other sound distortions. Without AEC, this echo can
detract from the quality of a call and in extreme situations, the echo
can degrade the audio experience to the point where the audio is
useless.
To prevent this from happening, the AEC component monitors sounds
being played by your computer's speakers while monitoring the incoming
sound picked up by your computer's microphone. The AEC module takes
the outgoing and incoming sound signals and compares them to determine
if echo is present. If echo is found, it is subtracted before the
audio from the microphone is sent to the requesting application. This
will result in the remote party only hearing you speak, without being
distracted by hearing their own voice echo back to them.
When enabled, echo is eliminated for the recipient of the
audio/video message. For echo free chatting, both parties need to have
a RightSound technology enabled web camera that supports the AEC
feature.
yeah, mine does it too. I hear fine, but everyone else complains of a nasty echo. :(
Just got a Motorola h500 headset. I can hear a caller just fine, but they cannot hear me. At all, basically. What can I do?
