So I just upgraded to Vegas Pro 17 (from 15) and when I put in an MP4 file with Multiple Audio tracks it only displays the first one. I tried looking on YouTube and I can only find issues related to it with OBS (I use 'Action') where they change settings within the program.
The tracks work fine when I preview them in Action but when I put it in to Vegas there is only one and I have no clue why it worked in 15 but now not in 17.
Any help would be much appreciated!
