cdparanoia sets consecutive timestamps on buffers (just for the sake of having 
a timestamp, it seems), which are just steadily increased and not affected by 
seeking, changing of tracks etc. 
 
This means that a query on the audiosink (or cdparanoia) will produce a time 
stamp that has no relation to the position currently being played back, which 
seems very undesirable for audio players etc. 
 
Instead, cdparanoia should set timestamps on buffers that represent the 
current position within the CD, ie. since the start of the CD, and send 
discont events on seeking/track changing IMHO. 
 
Patch attached. 
 
I realise the hack with g_object_{get|set}_qdata() is ugly, but it's the only 
sane way I could come up with to compensate for the missing padding. 
 
Tested with alsasink and artsdsink.
