No audio on camcorder recordings

[John_Cline]

I have an S4 with the latest, stock Verizon firmware, over 50% of the time that I record video with the stock camera app, there is no audio recorded, there is an AAC audio stream in the file, but it is silent. Anyone else experiencing this?

Here are the MediaInfo stats on the latest failed recording, the AAC audio is typically encoded at a constant bit rate of 128 Kbps but the failed recordings are encoded at only 4.125 Kbps.
