Hello, I've bought today the Magix Movie Studio but the problem I encountered today is about audio. I record from Nvidia GeForce Experience in .mp4 video extention with 2 audio samples split (1 audio is for my mic, 2nd for games' sounds, Windows sounds etc...) I have a problem with the 2nd audio sample. The program just doesn't play the audio (I see video and hear my mic but nothing from the Windows). I worked on this project on Vegas Movie Studio Platinum 17 (yes, the one produces by Vegas and yes, I know the 18th version is from Magix but I didn't have a choice since I am the EU citizen). I saw that HEVC codec can be bought but the video is fine. Could you help me with that problem? (Edit: the 2 samples are the same, I do not see the sample with windows sound)
