Problem with audio PES header

[Chris Worley]

My hardware's MPEG2 encoder output is in the form of PES streams, vlc
seems fine with the video packets, but is not producing any sound.  I've
traced through the audio decode thread, it seems to be walking through
the audio data correctly, but I'm really not sure where to look for
problems.

If I strip off the pes header and pipe just the sound through mpg123, it
will play correctly; so I figure the problem is in the PES header for
the audio.

Could anyone proficient at MPEG sound headers scan this for problems? 
Here's an example chunk, from the beginning, of a 16 byte PES header
plus some of the MPEG audio data following:

> od -A x -t x1 ../test.mpeg | less
