Comments

Under the specified registry path, the SoundSaveDeviceName function locates the \Devices subkey. Under this subkey, the function uses the device’s name as a value name and uses the device’s type as the value to associate with the name. The function creates a device name from the PrototypeName member of the device’s SOUND_DEVICE_INIT structure. It obtains the device type from the DeviceType member of the passed LOCAL_DEVICE_INFO structure.

After the function is called, the registry should contain the entry HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\DriverName\Parameters\DeviceNumber\Devices\DeviceName, where the value of DeviceName is the device type.

Drivers that call SoundSaveDeviceName must remove the saved device name from the registry prior to being unloaded. Refer to SoundOpenDevicesKey.
