Sound
There are many technologies involved in a working sound configuration on a Linux system. Different types of hardware and drivers can further complicate the scene. With the 2.6 series of Linux kernels, the Advanced Linux Sound Architecture (ALSA) has been made the default sound system. The story doesn't end there, however. Many software programs continue to use the older Open Sound System (OSS), while others may use different sound daemons that may provide an easy interface to the programmer or may allow other features, like software sound mixing.
By default, Fedora systems uses the PulseAudio sound system and has ALSA enabled This basic setup is usually enough to get sound working on a Fedora system, but additional steps may be necessary to enable additional features or to get some programs producing sound properly. These steps may include adjusting mixer settings, configuring programs to use the correct sound system or daemon and installing additional software that some programs may take advantage of. In some cases, the normal utilities may also be unable to correctly configure the sound hardware, in which case more advanced techniques may be required.
