Phonon is the multimedia API provided by Qt.

Phonon is the multimedia API provided by Qt. It is the standard abstraction for handling multimedia streams within the KDE Software Compilation 4.

Features:

  • Centralized configuration of audio and video: configuration of hardware and media frameworks are offered in a single, centralized dialog.
  • Purpose driven design: instead of demanding that you select special audio outputs for applications, Phonon applications describe what kind of sound output they make and lets you select for these categories individually.
  • Automated device selection: pluggable audio and video devices like USB or Bluetooth headsets become easy to use with Phonon. Phonon acts on information and signals from Solid, which is KDE's hardware subsystem, and automatically makes use of new devices.

In order to provide sound, Phonon uses various backend libraries, like:

  • DirectShow Phonon-DS9
  • GStreamer Phonon-GStreamer
  • QuickTime Phonon-QT7
  • Vlc: Phonon-VLC

How to disable phonon?

How do you disable phonon in PySide? I am trying to use QWebpage and I don't want phonon to kick in, as the app I'm writing is a server side app, and has no need for media. I tried a few things but did not find any really relevant documentation.
