Hi All, I am trying to make a test topology using KS Studio. Basically, I want to play a sound through kmixer. I have instantiated the object under "KSCATEGORY_MIXER" called "Microsoft Kernel Wave Audio Mixer". It has 4 pins. It looks like I need to use in #1 to attach to the wave file. However, everytime I right-click, and then "Instantiate" that pin, I get "KsPinInst::KsPinINst: failed to create pin (pin id # = 1). I tried basing the instantiation both on "PCM (Standard) and PCM (Extensible)" It looks like it refuses to take? Any Ideas? Thanks, James ****************** 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.de/
