I managed to thoroughly reproduce my problem. please see the two sample
sources attached.

with switch.c, the element setup is like the following:

filesource1 -- decoder1 --\
                          |-- switch -- audiosink
filesource2 -- decoder2 --/


where decoder is mad, audiosink is alsasink. as you see from the output,
seeking on the src pad of each decoder works fine.


now, in switch_adder.c, the setup is a bit more complicated:

silence ---------------\
                       |-- switch1 --\
filesrc1 -- decoder1 --/             |
                                     |-- adder -- audiosink
silence ---------------\             |
                       |-- switch2 --/
filesrc2 -- decoder2 --/


the idea here is to play silence in each 'pack' up to some time, then
seek deoderX to an appropriate position, and play it from there. seek
here is also done on the src pad of mad, but unfortunately it doesn't
succeed...


What am I doing wrong?
