Audio directories have been added to the Solaris 9 operating environment. The /usr/include/audio directory is a new directory for applications' audio header files. The audio file format has a new header file, /usr/include/audio/au.h, and man page, au(4).
The /usr/share/audio directory is a new depository for miscellaneous audio files. The audio files from the /usr/demo/SOUND/sounds directory have been moved here. A symbolic link from /usr/demo/SOUNDS/sounds to /usr/share/audio/samples/au has been created. This link enables applications and scripts that already exist to run without failure.
Numerous bug fixes have been made to the audio kernel modules to improve reliability.
