ACMDM_DRIVER_NOTIFY lParam1 = reserved // should be ignored lParam2 = reserved // should be ignored
Sent to an Audio Compression Manager (ACM) driver to notify the driver of changes that have taken place to one or more global drivers.
An ACM driver can use the ACMDM_DRIVER_NOTIFY message to determine when changes are made to one or more global ACM drivers. This includes driver additions, removals, priorities, and enable or disable operations. If a driver has cached any information about other ACM drivers, it must refresh this cache completely each time the ACMDM_DRIVER_NOTIFY message is received.
