eSpace Desktop -- User cannot hear if he use headphones when making call via eSpace desktop.

Possible Causes

• You or the peer party logs in to the eSpace Desktop using the remote desktop function.
• The audio card or headset is faulty.
• When the operating system of the client PC is upgraded from the Windows XP to Windows 7, two loudspeakers with the same device name and ID may appear. One functions properly while the other does not. If both loudspeakers are enabled and the one that does not function properly is set as the default audio output device on the client, the participant cannot hear other participants.

Troubleshooting

1. If you or the peer party logs in to the eSpace Desktop using the remote login function, local audio signals cannot be transferred to the remote PC; therefore, a one-way voice issue occurs. Log in to the eSpace Desktop on the local PC and make a call again.
2. Verify that the audio card and headset function properly.
   1. Click your profile picture in the main window, or click in the lower left corner of the main window and choose Settings.

      The Settings dialog box is displayed.

   2. Choose Media.
   3. Select the audio input and output devices as required, as shown in Figure 10-2.

   4. Click in the Audio Input area and speak into the microphone.
      • If the level meter changes with your voice, the audio input is normal.
      • If the level meter does not change with your voice, the audio card drive, hardware, or microphone may be faulty.
   5. Click in the Audio Output During Call area.
   • If you can hear the music using the headset, the audio output is normal.
   • If you cannot hear the music using the headset, the audio card drive, hardware, or headset may be faulty.

3. Disable the loudspeaker that does not function properly in the operating system.
   1. Choose Start > Control Panel.
