 Hi , We want to play MPEG2 video file which has  4 chnnels of audio . All this would be rendered on decklink card using Graph edit . So far i am able to decode the Mpeg2 file using Elecard Decoder .. the problem comes in audio
Now this is how my graph looks like :

                                                     video pin   
                                                     |---------------->Elecard VIDEO Decoder (filter) ---->decklink video renderer
file source(Asyn)------Elecard Demulplexer (filter)     
(filter)                                            audio pin
                                                     |----------->Elecard Intree (filter) ----> Elecard Audio Decoder (filter)--->Decklink Audio Render (filter)
                                                     |                                ----> Elecard Audio Decoder (filter)--->Decklink Audio Render (filter)   

                                                     |audio pin
                                                     |----------->Elecard Intree (filter) ----> Elecard Audio Decoder (filter)---> Decklink Audio Render (filter)
                                                     |                                ----> Elecard Audio Decoder (filter)--->Decklink Audio Render (filter)

The video play exellent on this .. but Audio channels get mixed up .. Ideally 4 different streams of Audio + Video should be embedded single SDI output. Where as the issue here is all 4 channels are getting mixed on either 1 st channel or 1 st and 2nd channel .. How can i put each audio stream on different channels as per the source file
