Shared object used to restore an audio driver's state

Note: You don't invoke this object directly; io-audio loads it on loading a new driver.



Runs on:

QNX Neutrino




When io-audio loads a new driver, it uses the 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.

Note: This shared object is an optional component of the audio system. If io-audio can't load it, io-audio continues, but doesn't restore the driver state. See also the io-audio global option config_write_delay.


When an error occurs, sends a description of it to the system logger, slogger2.
