[PyQt] Playing an ogg file with QtMultimedia?

Hello,
I have played my sound file in pygame, VLC and Audacity.
What is Slicer?
I am on Windows 7 64 Bit, so that may be part of the problem. Is there
another audio type other than ogg that is more multiplatform? (That is
not wav!)
Here is my not working code:
import sys
from PyQt5.QtWidgets import QApplication, QWidget
from PyQt5.QtCore import QUrl
from PyQt5 import QtMultimedia
from qt_tools import key_text
class Window(QWidget):
def __init__(self):
super().__init__()
self.player = QtMultimedia.QMediaPlayer(self)
self.sound =
QtMultimedia.QMediaContent(QUrl.fromLocalFile("draw_sword.ogg"))
self.player.setMedia(self.sound)
self.player.setVolume(100)
self.show()
def keyPressEvent(self, e):
key = key_text(e.key())
if key == "space":
print(self.player.errorString())
self.player.play()
app = QApplication(sys.argv)
window = Window()
sys.exit(app.exec_())
