IMiniportAudioEngineNode::GetDeviceChannelVolume
Decscription:
When handling GET volume KS property for the device, Portcls calls
this method, inside its property handlers, to get the current setting on the specific channel.
Parameters:
_In_ _ulNodeId: node id for the target audio engine node
_In_ _uiChannel: the target channel for this GET volume operation
_Out_ _pVolume: a pointer to a LONG variable for receiving returned information
Return Value:
Appropriate NTSTATUS code
Called at PASSIVE_LEVEL
