An interface implemented by ports to provide notification helpers to miniports to support audio module communication.
For more information about audio modules, see Implementing Audio Module Discovery.
The miniport audio driver will call into their port to create and send the notification.
The IPortClsNotifications interface has these methods.
|IPortClsNotifications::AllocNotificationBuffer||Allocates a buffer of the specified size, in the specified memory pool, for use in sending notifications, to allow for communications between audio modules and UWP apps.|
|IPortClsNotifications::FreeNotificationBuffer||Frees a previously allocated IPortClsNotifications buffer. The buffer is used in sending notifications, to allow for communications between audio modules and UWP apps.|
|IPortClsNotifications::SendNotification||Sends a notification to the listening UWP apps, to allow for communications between audio modules and UWP apps.|
|Minimum supported client||Available in Windows 10, version 1703 and later versions of Windows.|
