Interesting, I should have read the source earlier. I started working on
a patch that would take upstream timestamps in interaudiosrc into
account and in my test it seems to work, although I surely have ignored
a whole lot of complexity.

My questions would be, if such a patch would be interesting enough to
file a ticket for it?

My hack currently will return buffers that do not form a continous
stream. It may be that a buffer on timestamp 1.000 with a duration of
1.000 is followed by a buffer at timestamp 2.200

Do you know how sinks handle such gaps? neither mpegtsmux nor
xvimagesink seemed to have a problem with it but I don't know if I can
count on this.

Thank you very much for pointing me into the right direction.
Regards, Peter
