This sounds like you want to disable DND (do not disturb). The action for that doesn't require root. It's in audio category. The "all" setting will allow all sound, effectively disabling DND. I believe you must enable Tasker's notification setting in the system settings (main OS, not Tasker). If you are using any relatively recent Tasker version, you should be prompted for any missing permissions the first time you setup the (any) action.
Can system settings be changed without root
I have gone into settings then sound settings
I then get an if statement ....
Yes, Tasker is designed to run most of its actions without needing root. You do need to give permissions through ADB for some restricted actions, such as using the AutoTools plugin -> secure settings action. I think this is the action you are asking about. See Tasker User Guide - Grant Secure Settings
I have no idea what you mean by "I then get an if statement".
If you have a task (or profile) that doesn't work the way you expect, it helps others help you if you post the entire task (profile).
Before exporting, if you have sensitive information such as logins, api keys or anything else, you might consider setting those values to a variable and use the variable in your tasks so the values won't export with the task.
To export a task (profile) description for posting, press on the name to highlight the task (profile). Go to the 3-dot menu and select export -> Description to Clipboard.
Now you'll be able to paste it. Be aware, it easier to use something like pastebin.com / hastebin.com and link to a post here. If you paste directly into a post here, the forum software will convert semicolons with characters directly after, into emoticons making it very hard to read.
