This is my first post on these forums, so I hope I've found the right place to raise this? I'm doing some VO recording and want to combine my audio tracks into one audio track. I have source #1 set as WASAPI playback device source #2 WASAPI capture device with Mic in at rear panel (pink) - which it is Downmix is not checked since in Win7 its set to stereo And I have checked Mix multiple audio tracks. Game Audio and the Mic records fine but using media info I can clearly see there are two separate audio tracks recorded in the video. My understanding is that 'Mix multiple audio tracks' should combine all the audio to one track - is this correct as its not working? OR am I wrong OR missing a setting somewhere else? MSI AB is version 4.1.0.7013 Any help greatly appreciated! Win7 Pro x64
