Dear all : I am develop a Audio Mini Stream Driver . More like AVStream on he XP/2000 . When i install the multi audio device, the filter of "Audio Capture Sources" will come out multi audio driver names "Audio Driver" "Audio Driver (2)" "Audio Driver (3)"....... I think the sysaudio will auto increase the number of friendly name . So. How to rename the filter friendly name ?? How is windows decide the order, I means which device is one , which device are two ?? Thanks for any help, Small Chang ****************** WDMAUDIODEV addresses: Post message: mailto:wdmaudiodev@xxxxxxxxxxxxx Subscribe: mailto:wdmaudiodev-request@xxxxxxxxxxxxx?subject=subscribe Unsubscribe: mailto:wdmaudiodev-request@xxxxxxxxxxxxx?subject=unsubscribe Moderator: mailto:wdmaudiodev-moderators@xxxxxxxxxxxxx URL to WDMAUDIODEV page: http://www.wdmaudiodev.com/
