Home » Applications » Multimedia » Phonon
Phonon is a multimedia, multi-platform sound framework for the application developer. Phonon also provides several features and benefits for the end user.
Merkmale
- 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.
Configuration
Phonon can be configured through the Phonon Configuration Module available in System Settings under Multimedia. For a guide of the available options, look at the Phonon handbook.
Problemlösungen
Kein Ton
Mögliche Ursachen für fehlenden Ton.
Incorrect default ordering of devices
Phonon automatically chooses available audio devices for the best sound. Unfortunately this doesn't always work. Look at Getting Involved for information on how you can help fix this.
Fehlende Einträge für Geräte
Perhaps Solid or other system libraries are reporting the same name for several devices, which makes Phonon unable to properly display these devices. Please see Getting Involved on how to help fix this.
Kann auf Audio-Gerät nicht zugreifen
If your user account has insufficient permissions to access the audio device, Phonon will be unable to play sound. Please consult the documentation of your distribution on how to ensure that your user account is properly set up. If Pulseaudio is not used, make sure that your user account is a part of the audio user account group.
Ton aus dem falschen Gerät
This is related to the point above this. Also make sure that the correct device is listed at the top of the Device Preference tab, which can be found in the
area of System Settings. In case an audio device isn't available (an USB-headset unplugged, for example), Phonon will attempt the next device in the list.Phonon verursacht einen Absturz
Please search on bugs.kde.org to see if the bug is already reported. If it is not, please report your bug in detail. If the report already exists but you have new information, please add your new information to the existing report.
Geräte von ~/.asoundrc oder /etc/asound.conf werden nicht aufgeführt
Make sure you have a name hint set for your device. An example of a complete device entry, with a hint:
pcm.softvolPhonon { type softvol slave.pcm "default:CARD=0" control { name "Phonon" card 0 } min_dB -51.0 max_dB 0.0 resolution 100 hint { show on description "My Soundcard with extra Volume Control" } }
Systemsettings crashes when selecting Phonon
This is likely because you have xine as a backend. Please remove the file ~/.xine/catalog.cache and try again.
Backend-Bibliotheken
Phonon makes use of backend libraries to provide sound.
- Phonon-GStreamer: GStreamer is a multimedia library from the GNOME project. Phonon-GStreamer is currently the recommended Kubuntu backend, and under heavy development.
- Phonon-VLC: VLC is a very popular cross-platform media player. This is also under active development, and is receiving a lot of work from both VLC and Phonon developers.
- Phonon-Xine: Formerly the most popular backend for Phonon; now unmaintained, and deprecated.
- Phonon-DS9: Native backend for Microsoft Windows utilizing DirectShow 9.
- Phonon-QT7: This is a native backend for Mac OS X, utilizing QuickTime 7.
- Phonon-MPlayer: This was a third-party backend for Phonon, now unmaintained.
- Phonon-NMM: This is an abandoned and unmaintained backend started by the Graphics Lab at Saarland University and Motama.
Mitmachen
There are several ways you can get involved as a user.
- Promotion: KDE and Phonon are awesome! Spread the word.
- Appreciation: Encouraging words can help lift the spirits of weary multimedia developers way beyond the clouds, when faced with nasty bugs and other challenges. Positive emails, messages on IRC, beer, pizza, gadgets and other developer fuel is very welcome!
- Quality assurance: Simply run and use Phonon, and report bugs and irregularities to the developers.
- Documentation: You can help expand this page and other Phonon documentation. It doesn't take much to help, and it helps!
