Default whiney hum

Hi folks, not been about for a while, hope all are well...

I have developed a whiney hum, well, not me perse', more the V70 and it sounds like the NSF, but meh, no telling is there, its fairly quiet and my mate couldn't hear it till I really pointed it out.

Theres no change in sound at all, not when cornering, either direction.
It doesn't change with speed, that I can tell, the only time it stops is if the car
is stationary or, as a test, i put it into neutral and i think it stopped then once the revs dropped off.

Dont say pulley, please, just dont
I initially thought bearing, but i thought that they change in sound depending on what the car is doing.
Im also thinking poss driveshaft, or CV, but more leaning towards pulley, see, ya made me say it..

Also i think its getting a bit louder over time, prob noticed it about 1k ago and it was barely noticed able, and now it think it would be easy to point out
