[Galaxy S6 Edge Q&A, Help & Troubleshooting] gg48gg:
The tasker profile is only working sometimes for me now, unfortunately. I think it has to do with how fast tasker is able to respond to the "charging" event. Sometimes playing the audio wins out in priorities, and the annoying sound plays. I chatted with Samsung online about this and below is their official response to this issue. In short, they recommend removing the phone from the charger when the battery is full, regardless of charging method. This is consistent with the online user guide as well. This is unfortunate, since most of us charge our phones overnight on our nightstands or desks.
