I have set up my 737NG for P3DV4 without a problem, except one.  I have worked through the FMC setup for the PMDG aircraft, paying close attention to the sound settings.  I have set the sound to come through my headset.  I also configured the aircraft through the FMC to read out all heights below 1000 ft until landing.  I have set the volume to be above 60 (using the scale of 0- 100).  All sounds, except the callouts seem to work correctly.  Any suggestions on what I might need to do in order to hear the callouts during landing?

Strange, have you tried disabling all of them and then reenabling them? That might solve it, if it doesn't then submit a support ticket and PMDG will sort it out for you.

Check your windows sound device settings. Do you have a sound card? You could try updating the drivers.

The solution to everything isn't to flood PMDG with support tickets, it's best to try basic troubleshooting techniques first so PMDG don't have to go through it all

Usually, this is caused by not properly setting up your sound devices in:

Windows (right click the speaker icon, bottom right, select playback devices, and ensure you have the proper device selected)
FSX/P3D (go to your settings page)
PMDG SETUP (check the sound settings there as well

Thanks for all of the suggestions!   I redid the sound pages and now the sound works.
