Galaxy S6 :: Boot Sound Locked When Using Encryption

I just want to preface this by saying I cannot root my phone. Not because I am incapable but because this is my corporate phone and I would no longer be able to use it for work related things if I rooted it.

I am using a Bell Canada Samsung Galaxy S6. Every person I've come across that has an S6 or newer samsung phone is able to boot up on silent and not get the samsung noise when the logo comes up. I tried doing a hard reset on my phone just to test to see if my phone would boot silently if I set it on "Mute" mode and it did WITHOUT encryption but I am forced to use encryption by my company's device management policy app or I can't access other things like my e-mail.

How to get the device to boot silently without rooting with these factors in mind? I reached out to samsung and they were clueless. As far as the support knows, the phones cannot boot without the noise even on "Mute" mode which is clearly not the case.

I've tried the Silent boot app as well with no success. I've noticed this happens only when encrypted and upon checking the volume settings on the screen where you have to put your encryption password after booting up, the volume settings are kicked back to default.
