OK, here's the issue now. I should have been more thorough in my OP. The notification sound is playing on the phone if I navigate to it and play it using the stock music player. There are three notification sounds that are heard depending on the app. One is for the texts and that one I can't change unless it's a preinstalled sound. Another is for all other notifications and the sound I want for texts is coming through for those. The third is for Facebook and that one is like a vibration but is audible. I've tried to download the sound again from Zedge and from other locations across the web and get it to work for texts, and still nothing. Usually on older phones I've just went into the text app or Sound settings and tell it what sound I want and I'm good. This is infuriating. I'm assuming that Nougat along with the LG OS is causing an issue. Maybe I'm wrong.
