Ps4 not making the beep sound when turning on

Hey ps4 sub.

Lately I've been playing a lot of ff12 tza and when i turned on my ps4 after a 2 hour rest, the beep noise you hear when starting up doesn't happen. I tried googling as well but the one answer I found (from this sub btw) sounded more like satire than an actual reason. Is there something wrong with it or is it just me?

Thanks in advance!
