Frequently Asked Questions
I plugged the GN8110-USB in but the sound is still
coming through the sound card.
• Go to Start/Settings/Control Panel. Double click on the
Multimedia icon to bring up the Multimedia Properties win-
dow. Click on the Audio tab. Under Playback and Recording,
choose the USB Audio device as the preferred device. Select the
Use only preferred devices box. Click OK.
Why can’t I listen to my RealAudio files with the
GN8110-USB?
• USB audio devices do not always work with RealAudio players.
This is due to the RealAudio software design. You can listen to
various digital audio files such as MP3 and Wave, through the
USB using Microsoft’s MPlayer and other players.
Why can’t I listen to my music CDs through the
GN8110-USB?
• Standard PC CD players do not support USB audio without
additional software. Go to the GN Netcom USB website at
www.gnnetcom.com/usb for an update on the availability of
this software.
Why can’t I hear my voice when I record a voice file in
the Sound Recorder?
• Check that your speaker volume is set properly. Go to
Start/Settings/Control Panel. Double click on the
Multimedia icon to bring up the Multimedia Properties win-
dow. Click on the Audio tab. Click the Playback button to
open the Speaker window. Be sure that the Speaker Volume
slider is set at least to the middle and the Mute all box is not
selected.
• Check that your microphone volume is set properly. Go to
Start/Settings/Control Panel/Multimedia Properties/
Audio/Recording to open the Microphone window. Be sure
that the Microphone Volume slider is set at least to the middle
of the control.
• Record a new voice file. Replay the file. If you can hear your
voice, recording is successful and the microphone is working
properly. If you still cannot hear your voice, contact
GN Netcom customer service at 1-800-826-4656.
Volume Controls
21. The volume for both
the speaker and microphone
are controlled by software.
Go to Start/Settings/
Control Panel to access the
Control Panel window.
Double click on the
Multimedia icon to bring
up the Multimedia
Properties window.
22. The Audio tab in the
Multimedia Properties
window lets you adjust the
Playback or speaker levels
and the Recording or micro-
phone levels.
23. Click the Playback
button in the Audio tab
to open the Speaker win-
dow. These controls allow
you to adjust the volume
output level for different
sources independently.
Most levels are adjusted
by the Speaker or Wave
sliders.
24. Click the Recording button in the
Audio tab to open the Microphone window.
Adjust the Volume sliders to the desired
levels.
Note: These controls adjust the volumes,
however, many other applications contain their own volume
controls as well. These independent applications may override the
Windows controls and work independent of the GN8110-USB
sound controls. Consult your software owners manual if you have
any questions.
Special Features
The GN8110-USB has several unique features to deliver superior audio quality. These include:
• Echo cancelation eliminates the distracting repeat effect common to Voice over IP applications (VoIP).
• Side tone allows you to hear your own voice in the headset speaker. It is part of regular telephone calls, but is not typically a part of
Internet/PC-based telephony.
• SmoothStream™ audio correction improves the sound of IP telephony calls by reducing the clicks and pops from lost bits and dropped
packets.
These features are preset at the factory to be active. If you need to disable these features, special software is available to help you do so.
Contact GN Netcom customer support at 1-800-826-4656 or visit the GN Netcom USB informational site at
www.gnnetcom.com/usb.
