Sound Card Issues

Main  Previous  Next

You can adjust the SJphone sound characteristics using standard Windows audio controls or controls on the Main panel. The Mic and Speaker controls are connected with the standard Windows audio controls. Any changes in their settings automatically change the corresponding settings at the Windows volume control panel.

 

You may also use an Audio Wizard to fine tune your sound system for work with SJphone.

 

SJphone requires a full-duplex sound card. You can check whether your sound card is full duplex. Try to record sound from the microphone with the Sound Recorder while another copy of the Sound Recorder plays back any sound file. If you can do this, your sound card is full duplex. If you cannot, your sound card driver may be not full duplex. Obtain a full duplex driver from the sound card manufacturer.

 

You can use the automatic microphone gain feature in your sound card to automatically adjust the input sound level. Consult your sound card documentation for details. Some sound cards do not have the automatic microphone gain feature. You can select the Automatically adjust microphone volume box on the Audio tab to let SJphone automatically adjust the microphone sound level.

 

If there is a strong background sound when the Automatically adjust silence detection level on the Audio tab is activated, SJphone may not detect silence correctly, and fragments of your speech may be lost. In this case, turn this feature off.

 

If your sound card supports DirectSound, select the Enable Direct Sound for improved audio performance box on the Audio tab. This will decrease sound latency time. Most sound cards from Turtle Beach, Yamaha, Creative Labs (excluding the Ensoniq-based AudioPCI types), Diamond, Crystal, or Microsoft USB speakers support this feature.

 

If you are using DirectX option, make sure that you have DirectX 7.0+ installed. You can check it with dxdiag.exe.

Attention Windows NT 4.0 users! SJphone does not support DirectX on NT 4.0.

 

If you hear hissing noise from your speakers while talking, try the following:

 

Move the microphone farther from the speakers.
Decrease the microphone or speaker sound level.

 

If the problem persists, contact SJ Labs technical support.
