Is there a way to get rid of the audio fade-in?

I've spent way too many hours trying to figure this out through forum posts.

As far as I could gather there was a configuration file that could be edited but now that configuration file is nowhere to be seen so I need to create that file but I'm not sure what to pun in that file.

The other problem is that all forum posts that talk about editing a configuration file is for something called Pulse and some forum posts mention that Mint doesn't use that anymore, so back to 0.
