Could also be power steering pump.
I was going to mention idler pulley. I had to replace one a few years ago and you can use a long funnel or even a 2 liter soda bottle with the bottom cut off to help isolate the noise so you know which one it is.Hello,
What ended up happening with this issue.
I'm in same position with 93,XXX miles.
I'm gonna start with belt and idler pulley.

Hey There,
This is my first post on here, I have a 2015 subaru XV with 117k and haven't had too much maintenance to deal with up until this point. However, I am having this whining noise at all rpms, and it is especially noticeable during the high idle period after starting. The AC compressor switching on does not change the sound much. During research people have said that it could be the idler pulley or the water pump bearings. However, when I sent it to a friend thats super familiar with cars, it was not the sound he was expecting. I've never replaced the belt, so going to start with that for sure and investigate all the pulleys. I've attached a video of the noise right after starting. Any advice is appreciated, thank you!

I had the EXACT same noise. It was a cheap simple fix. IDLER PULLEY $67 bucks. BAM! Piece of Cake.Hey There,
