Your voltages are fine. You need to take another look at your wiring.

Update: Brian beat me.

Did you use an audio prob yet? You can check the PT2399 in/out pins for any audio. Check pins 9-16 for audio.

With a quick forum search I found this thread that may help you

Brian posted voltages and others gave some tech help. Hope it helps you out.
