There have been reported cases where a user has music playing through iTunes or another music player and then tries to access an audio enabled meeting using GP4.
When they don't have any sound in the meeting, they check their audio device lists in GP4 and find them blank with no options to select from.
To correct the issue follow the steps below.

1. Exit all programs including GP4.
   
2. Re-open GP4.
   
3. Check the Audio Device menus in GP4 again.
   
4. If this does not solve the problem, re-start the computer, open GP4 with no other programs running and check the Audio Device menus in GP4 again.

Some USB devices can cause conflicts which cause GP4 to not recognize all of the attached devices.
These can include iPod docks, The iMic adapter, USB hubs, etc.
To rule this out as a possibility, follow the steps below.

1. Shut down the Mac/PC.
   
   
2. Unplug all USB devices except the one needed for the audio (headset, speaker phone, etc.) and the mouse/keyboard (if applicable).
   This includes any USB hubs, iPod docks, flash drives, etc.
   
   
3. Restart the computer and check the Audio Device menus in GP4 again.
   If this corrects the problem, shut down the computer, plug in another one of the other USB devices, restart the computer, and check the device list in GP4 again.
   
   
4. Keep doing the previous step until all of the devices are connected or until one of the devices causes the problem with GP4.
