Hi all, I have some peculiar problem here, 1. I have developed an virtual audio device driver that is capable of sending audio (played by any player) over a network by socket connection. 2. i open an remote connection from another Linux machine (rdesktop IP). 3. if i open the socket and receive the audio packets and then if i play it, is playing perfectly. 4. Now in windows machine if i log in to different user and play an audio, this audio that is also being routed to the remote machine. How can i solve this problem, I want to route audio of only one session to the one established connection. I got some pointers 1. Can i use \\Session\\0\\DosDevice<device name> to restrict device to be loaded only for session 0. then how can i createfile in the user mode (by what name \\\\.\\name) 2. Or can i dynamically load the driver during each session? Thanks and Regards Karthik SG
