Audio not syncing with video's

[wolvie]

Sorry if this was posted before.
I use my USB cable to let my daughter watch video's so the sound comes through the radio, since she cannot hear the voice from the movie while I am driving down highway.
Anyway she tells me the lips/mouth don't work with the words. ( Voice not syncing with audio)
I watched the movie also and sure enough the voice and the mouth are not in sync. I know that using Bluetooth there is a slight delay. But using the USB before never had a delay, now every movie has it.
Is there something that got turned off on the phone?

Any help on this would be gratefully appreciated

Thanks in advance
