Fedora 11 ships with support for Ogg Vorbis, Theora, FLAC, and Speex, giving you the freedom to watch or listen to your media in a free format. Not only are they all open source but no codec that ships with Fedora contains any harmful patents or licensing fees.
MP3 and Flash
Because of patent issues Fedora can not ship with an MP3 decoder, however if you are unable to convert to a patent free codec, such as Ogg Vorbis, Fluendo offers an MP3 decoder that follows all legal requirements set by the patent holder. Visit Fluendo's website (http://www.fluendo.com/) for more information.
An updated volume control manager application provides you with more control over your audio preferences. Better integrated with PulseAudio, you can now control individual application inputs and outputs along with the sources and destinations for the audio.
Using the new PulseAudio-based volume applet, there is no way to adjust ALSA sound levels. If they are set too low, raising the PulseAudio sound levels may not work acceptably. For this contingency, the old
based volume application is also available by default. It is available under the name Advanced Volume Control, in the System / Preferences menu section. You will also need to use this application if you need to select an input channel for recording (for instance, line-in or mic-in).
OSS compatibility disabled
Support for the legacy OSS sound framework has been disabled because it can interfere with the PulseAudio sound service (a legacy OSS application can prevent PulseAudio applications from playing sound by preventing PulseAudio from (re-)opening the sound device). To re-enable support for OSS, edit the file /etc/modprobe.d/dist-oss.conf and uncomment the final line, as instructed by the text.
