Shared object used to restore an audio driver's state
QNX Neutrino
None.
When io-audio loads a new driver, it uses the deva-util-restore.so shared object to restore the driver's state, which consists of all the device settings, such as the output volume level and the selected input connection. The state information is restored from a file that was updated the last time the driver ran, which is located at /etc/system/config/audio on the filesystem.
When an error occurs, deva-util-restore.so sends a description of it to the system logger, slogger2.
