Hi John,

This is good info (especially since you have kernel timestamps enabled).

Did you have a specific reference to the USB audio spec which said the
packet size has to be on an integer boundary?  I took a look at the
spec last night and didn't see anything to that end.

Do you have a proposed patch to usbaudio.c which "works for you"?  If
so, feel free to send it along and I will review and provide comments.
 If the spec does not require the packets to be on an integer
boundary, perhaps the driver just improperly assumes they will be (and
they were for whatever developer wrote the original code).
