So, I'm pretty new to Sony Vegas, and... after working on a video for quite sometime I rendered the video to just test how rendering works and find my personal settings that worked best for me. Now, everything seemed just fine at first, but when I recently tried to render it after more working on my video... the distorted sound effects disappeared completely, every audio track were I added distorted sound effects were just gone... But it only happens after the video is rendered, in sony vegas everything sounds like how it should be. Whats even more strange is that after trying to render it a few more times, the distorted sound effect was back again working as it should after my third time-ish of rendering... but now, it's gone back to not have the effect anymore. I don't have any clue to why this is happening, and it feels like I just have to cross my fingers and hope that the effect is still in the video after rendering and just keep trying and render it, and render it until the effect is working. This is really frustrating, and I would really appreciate if someone has anything to say about this issue, if someone has a fix for this, or just if someone is having a same issue, please let me know! Thank you for your time.
Edit: Of what I can see, it seems like any changes to the audio tracks disappears, if I change the volume or do anything that changes the audio it will reset back to its original state.
