I have just recently got a Magewell Pro Capture HDMI card...

http://www.magewell.com/pro-capture-hdmi

the main reason i got this card was the spec sheet said 'Support for up to 8-channel IEC60958/IEC61937 audio streams', so basically capture 5.1 and 7.1 audio for your captures. Upon receiving the card i was unable to find an option to select 5.1 or 7.1 audio from there supplied Capture Software (Magewell CaptureExpress)....

in the end i found out i needed to download MWCaptureSDK.zip file from their site...

http://www.magewell.com/files/MWCaptureSDK.zip

in the zip file i found a program named, XID_MultiAudioCapture.exe, which indeed allowed me to capture 5.1 audio from my xbox one console, but just the audio no video!!. So in order for me to capture my gameplays along with 5.1 audio i need to run both the CaptureExpress software (for video) and XID_MultiAudioCapture software (for audio) AT THE SAME DAMN TIME. This to me seems ridiculous, if the hardware supports the ability for capturing 5.1 audio then why not include the option in there main capture software program rather than going the half arse way and making the user have to run 2 programs at once!!??, as it stands atm im left with 2 files, which isnt ideal really.

Is there a way in AvsPmod (Avisynth) to add both the video and audio files so i can edit the 2 files together at the same time, so what ever cuts i make to the video will also cut the audio at the same point?

At the moment my AvsPmod scripts look like this...

video=DirectShowSource("E:\Video Captures\2015-11-17-1939-59.flv")
video1=DelayAudio(video,-0.280)
video1=trim(video,60,2416)
video2=fadein(video1,50).fadeout(50)
return video2

in keeping with that format how can i add the audio file into this script so editing would edit both files at the same time (if thats possible)?

As at the moment, i would have to combine the 2 files together and THEN edit this new combined file in avisynth??

AviSynth supports editing both the audio and video at the same time.

Ah, the output audio file is in .wav format, what plugin do i need for AvsPmod to work with that file?
