It was pretty much the same in SH3 and 4 , although you didn't have those orange circles there. AI was always able to hear you while in silent running regardless of depth. That's why modders decided to keep unrealistic depth maintaining with 0 knots speed so that player can select all stop and avoid hydrophones detection.
So no, this isn't SH5 AI problem...It's SH AI problem in general. But at least, in SH5 we have engine man passive ability to silence the engines in order to somewhat ease this problem, which wasn't the case in previous versions...
