I don't get this. I copy/pasted the code used for regular timestamps. 
Why should it be any different for audio timestamps?

Again I don't see why I should make a difference between tstamp and 
audio_tstamp? It's really the same type, so either my code is correct or 
the existing code is wrong as well.
All other comments fixed, thanks for the review.
