That is super interesting and I will keep my eyes open for PS hose leaks.
I changed my serpentine yesterday and the whine was still there so I stethoscoped around the front of the engine and idlers and one idler was making the noise form the bearing. $20 OEM part.
Funny because when it would whine and you turn the steering it would get louder. It would also change tone with RPM. So I was sure it was PS pump noise.
I ordered it from RockAuto and I have a couple days to wait so I just pulled a seal on the OE idler and packed in some general purpose grease and reinstalled the seal. Noise is gone.
