The ossdevlinks utility creates and manages old style (legacy) device files for OSS audio, MIDI and mixer devices.
In previous versioms OSS used "flat" device numbering for the device files (for example /dev/dsp0 to /dev/dspN). OSS version 4.0 and later uses different naming scheme. The ossdevlinks utility is used to manage the legacy device names as symbolic links to the new style devices.
Normally ossdevlinks is used without command line arguments. However there are few command line options.
|-r||Reset the legacy device numbering (do not use).|
The -r option will invalidate audio device selections in the setup files of various applications. This is considered highly undesirable. Applications using wrong audio devices may cause serious security and privacy problems. For this reason the -r option should never be used unless there are no other ways to recover from serious audio/sound related problems. After that users should review the audio settings of all the audio applications they are using.
