Troubleshooting Audio Features in Microsoft NetMeeting
http://support.microsoft.com/default.aspx?scid=kb;en-us;Q155030
This article was previously published under Q155030
SUMMARY
This article lists steps to help you troubleshoot problems using the
audio features of Microsoft NetMeeting.
MORE INFORMATION
To troubleshoot problems using the audio features of NetMeeting,
perform the following steps. After performing each step, check to see
if the problem has been resolved.
Step 1: Can You Use the Audio Features of NetMeeting?
Verify that the person you are connecting to can use the audio
features, that you are not hosting a conference, and that you did not
place a data- only call.
If the person you are connecting to cannot use the audio features of
NetMeeting, you are unable to use the audio features when you connect
to that person. To determine if you are unable to use the audio
features of NetMeeting because the person you are connecting to is
unable to use the audio features, connect to another person that you
know is able to use the audio features. If you are able to use the
audio features then, the problem is caused by the fact that the person
you originally connected to cannot use the audio features of
NetMeeting.
When you host a NetMeeting conference, you cannot use the audio
features of NetMeeting. If you are unable to use the audio features of
NetMeeting because you are currently hosting a conference, there is no
way to use the audio features without ending the conference and
starting another meeting.
By default, NetMeeting attempts to use the audio features when you
place a call. However, you can use the Advanced Calling command on the
Call menu to specify that the audio features should not be used for a
particular call.
If you are participating in a meeting and are unable to use the audio
features because you started the meeting by placing a data-only call,
there is no way to use the audio features without restarting the
meeting.
Step 2: Check the Sound Card Driver Configuration and Functionality
Verify that the sound card drivers are undamaged and are configured correctly.
For information about how to do this, contact your hardware manufacturer.
If the sound card drivers you are using are configured incorrectly or
are damaged, note that you may be able to work around the problem by
reinstalling the drivers from the disk provided by the hardware
manufacturer.
NOTE:
The sound card drivers included with Windows do not support full-
duplex audio. If your sound card supports full-duplex audio, you must
obtain full-duplex drivers from the manufacturer of the sound card to
use full-duplex audio in Windows. To determine if your sound card is
configured for full-duplex audio, start two instances of Sound
Recorder. Using both instances of Sound Recorder, play a Windows sound
(.wav) file and record a .wav file simultaneously. If you are able to
do so, your sound card supports and is configured for full-duplex
audio.
Step 3: Check for Device Driver and Memory Resident Program Conflicts
Verify that the device drivers and memory-resident programs loading in
the Autoexec.bat, Config.sys, System.ini, and Win.ini files are not
conflicting with the audio features of NetMeeting. For information
about troubleshooting problems with incompatible device drivers and
memory- resident programs in Windows, please see the following
articles in the Microsoft Knowledge Base:
136337 Troubleshooting Windows 95 Startup Problems
140441 Creating a New System.ini File Without Third-Party Drivers
192926 How to Perform Clean-Boot Troubleshooting for Windows 98
Step 4: Is the Sound Card Compatible with Windows?
Verify that the sound card installed in your computer is compatible
with Windows. The Windows Hardware Compatibility List (HCL) contains a
list of computer systems and peripherals that are compatible with
Windows. For information about obtaining the Windows HCL, please see
the following article in the Microsoft Knowledge Base:
131900 Windows Hardware Compatibility List
Step 5: Use the Audio Features Portion of the NetMeeting Troubleshooter
Use the portion of the NetMeeting Troubleshooter that corresponds to
the audio features of NetMeeting. To do so, view the "NetMeeting
Troubleshooter" topic in NetMeeting Help, click "I'm having trouble
using the audio features," and then follow the instructions on the
screen.
Additional Notes About Why Audio Features May Not Be Working
To use the audio features of NetMeeting, you must be using a LAN or
Internet connection with the Transmission Control Protocol/Internet
Protocol (TCP/IP).
In addition, the audio features of NetMeeting cannot be used by more
than two participants in a single meeting.
If you are using a 14,400 bits per second (bps) modem connection to
connect to the Internet, you may be able to improve audio performance
in NetMeeting by reducing the number of programs that are running in
Windows. This includes programs associated with NetMeeting features,
such as Chat, Whiteboard, and other shared programs.
You cannot play sound (.wav) files in Windows when NetMeeting is
running and the audio features of NetMeeting are enabled. For more
information about this issue, please see the following article in the
Microsoft Knowledge Base:
154781 Sounds Not Played While Using Audio Features in NetMeeting
If you have more than one sound card installed in your computer, you
can use the Audio Tuning Wizard to select the sound card you want to
use with NetMeeting. The Audio Tuning Wizard runs automatically the
first time you run NetMeeting. To run the Audio Tuning Wizard after
running NetMeeting for the first time, click Audio Tuning Wizard on
the Tools menu.

Participants Cannot Hear During an Audio NetMeeting Conference

No Audio in NetMeeting with Wrong Playback or Record Sample Rate
http://www.kbalertz.com/Feedback_239817.aspx
SYMPTOMS
When you attempt to use audio in NetMeeting, you may not hear any
sounds, and this behavior may occur even though your sound card passed
the audio test.
CAUSE
This issue can occur if the playback and record sample rate for your
sound card are not set properly.
RESOLUTION
To resolve this issue, set the sample rate conversion quality to "best":
Click Start, point to Settings, click Control Panel, and then
double-click Multimedia.
On the Audio tab, click Advanced Properties in the Playback section,
and then click the Performance tab.
On the Performance tab, set the "Sample rate conversion quality" to
Best, click Apply and then click OK.
Click Advanced Properties in the Recording section.
On the Performance tab, move the Sample Rate Conversion Quality slider
to Best, click Apply, and then click OK.
Click OK to close Multimedia Properties.
MORE INFORMATION
The sample rate conversion quality is set to "Good" by default.
=================================================
No Audio or Video When NetMeeting Is Started During an Incoming Call
http://www.kbalertz.com/Feedback_243115.aspx
SYMPTOMS
If you start NetMeeting during an incoming call, audio and video may
be unavailable in your conference.
CAUSE
This behavior can occur if NetMeeting does not have sufficient time to
begin "listening" for an H.323 connection attempt. When this occurs,
the "caller" computer incorrectly interprets this to mean that the
call receiver computer does not support H.323, and then tries T.120
instead.
RESOLUTION
To prevent this issue from occurring, start NetMeeting completely
before your call is initiated.
To work around this issue, disconnect from your conference to free the
H.323 port, and then establish a new conference.
=================================================
Microsoft Netmeeting AUDIO COMMUNICATION
http://www.dcnicn.com/Help_Files/tutorial/netmeeting2.html
By default, audio communication is enabled for TCP/IP calls. Audio is
supported only over TCP/IP and between no more than two people. Sound
quality can vary significantly depending on your sound card and
microphone. To automatically adjust your settings, use the Audio
Tuning Wizard, available from the Tools menu.
