Hi,
I am trying to figure out how I can add wav files to phonon so it will
just play them all in the order added. Somehow phonon just plays one
file and then just a very small part of another. Anyone knows what I
am doing wrong here?

import sys, time
from PyQt4.QtGui import QApplication, QMainWindow
from PyQt4.QtGui import QFrame
from PyQt4.QtCore import SIGNAL, QObject
from PyQt4.phonon import Phonon
class MainWindow(QMainWindow):
def __init__(self):
QMainWindow.__init__(self)
self.sounds = [
#' /usr/share/kde4/apps/korganizer/sounds/onscreen.wav',

self.m_media = Phonon.MediaObject(self)
audioOutput = Phonon.AudioOutput(Phonon.MusicCategory, self)
Phonon.createPath(self.m_media, audioOutput)
QObject.connect(self.m_media, SIGNAL('aboutToFinish()'),
self.enqueueNextSource)
QObject.connect(self.m_media,
SIGNAL('stateChanged(Phonon::State, Phonon::State)'),
self.stateChanged)
self.m_media.setCurrentSource(Phonon.MediaSource
(Phonon.MediaSource(self.sounds.pop())))
self.m_media.play()
This is what I did in a similar situation:
self.player = Phonon.createPlayer(4, Phonon.MediaSource(self.sounds.pop
()))
self.player.tick.connect(lambda a, b: pass)
self.player.aboutToFinish.connect(self.enqueueNextSource)
self.player.stateChanged.connect(self.stateChanged)
self.player.play()
This uses the new-style connect API, which I personally found more
"readable"...
The only difference is the connection to the "tick" signal of the
player. It takes a callable,
in this case one that returns immediately.
That fixed the problem for me.

thx!
