S5 Tasker troubles

A

AC Question

Here it is everyone.

I he the S5 and just installed tasker and started checking out various profiles. Started small and all while learning how to use it on the android. The issue is one of the simplest things isn't working. Set up a profile to kick off Amazon music, max the media volume, and max the system volume when headphones are plugged into the device. Took it to the truck plugged in the aux cable, and no Amazon startup. Plugged in my actually headphones, and no Amazon startup. If anybody has got any ideas on how to get this to work or got anything similar going on I would appreciate a heads up.

Thanks
