- Store MiniportStream & pin instance in subdevice descriptor - Simplify irp handling code in class IIrpStream - Rewrite CPortPinWaveCyclic code to handle property request. It now uses PcHandlePropertyWithTable, which calls the supported property request handlers via a callback. The code is now a lot cleaner as KsPropertyHandler peforms input & output length checks and also handles basic support requests - Implement a Audio position handler for CPortPinWaveCyclic - Use the IDmaChannel::CopyFrom when copying sound bytes from an dma buffer. Fixes recording of sound with KsStudio - Make sure that the GUID_NULL handler only adds guid which are not already present in the guid array. Fixes duplicate entries of properties of Nodes in KsStudio - Handle Basic Support requests in a default way when the driver doesnt provide a BasicSupport handler svn path=/trunk/; revision=43414
