maybe.

the problem is many audio streams do not have presentation time stamps. 
(PTS) IE when to present it (absolute time)

Video+audio streams have relative PTSs  to ensure lip sync once 
presented to the user.

I have 3 different DAB radio sets in my house and they ALL have 
different presentation  delays so having the cricket on in different 
rooms with different radios is a audible delay mess.
