Volumes for ringer, Notifications and alarms keep changing, need APP to lock Volumes

[bmaz121]

My OnePlus One has had the volume changed many times. I was using Volume Locker app but it does not work anymore. Running ASOP Extended does not help with this problem. Anyone know an APP that will lock the volumes to max and keep it there without Notifications. I don't want the volume to change for anything.

Thanks
