Hello, I am looking for some help on an issue I am having. This issue started a couple of weeks ago, so I am assuming I accidentally messed with some of the audio settings in Vegas, and now I am not sure how to get them back. So, I normally edit with 5.1 surround 6-channel audio files. I choose the scenes I want from the trimmer and then will add them to my timeline from there. I will usually chose the "Use all streams and channels" option in the trimmer so that all audio channels are also uploaded onto the timeline with the scenes. However, recently, my first two and last two channels have started to automatically combine. So, instead of having all 6 channels separate, channels 1 and 2 & 5 and 6 combine. I have also attached a picture of what this looks like compared to what it used to look like when I added all channels to my timeline from the trimmer. For the past week I have been manually duplicating the first and last channel tracks then selecting each channel I want, but that is exhausting when I am working with multiple scenes. If anyone knows what setting this is or how I can get these channels to stop combining, I would really appreciate it!
