i'm sorry you were offended by my little attempt at humour (didn't you

yes. i'm no expert, but if i had to guess, i would say the bug (if it is
one) is most likely to be in Phonon, and not PyQt. i just had a google
for "phonon currentSourceChanged", and the third hit was this:


that bug is a couple of years old, but it seems to be very similar to
the problem you've raised. what version of Qt/Phonon are you using?

you may be right to get rid of Phonon. i havent't used it much myself,
but my initial impression was that it is very far from being the
finished article. if i was going to write a python multimedia app
myself, i would probably base it on gstreamer. it obviously has a much
steeper learning curve than Phonon, but that is because (at the moment)
it has much more to offer. if you're interested, there's some sample
code available on the PyQt Wiki, here:


finally, i have to say i think you would be making a big mistake trying
to switch from PyQt to PySide. i'm just a dumb user and have no real
stake in the matter, but i'm pretty confident that PyQt is going to
remain far superior to PySide for quite some time to come.
