Slight whine from inside the cabin

Hey everyone, I'm new to this thread. So last night I stopped to get the mail and turned the car off and then when I got back in I noticed a slight whining sound coming from the passenger side of the engine bay, or at least I think it is. I then turned the car off and back on to see if it would return, and sure enough it did. The car had been running fine and I hadn't noticed any noise for the 20 minutes or so previous.

This afternoon I turned the car back on to see if it would happen again and sure enough (garage kept about 35 F outside) driving to the store and back. I'm not sure what it is, and I've done a good amount of research around for this issue. People seem to think its the drive belt, or one of the pulleys, but I'd love to get your feedback. I took a video of it hoping to get this figured out. Its a very slight sound but you should be able to pick it up.

Car has just over 101k, I changed the oil and filter about 2k miles ago, mixture of highway and city driving, only hear it at idle or low speeds, not sure if it goes away at high speeds or I just can't hear it.

Video Link with sound:

Thanks everyone, I try to take great care of my care and this has me worried.

My alternator is making the same whine noise. My mechanic confirmed it's the alternator. I'm at 90k, I've had a sub and amp since 9k miles, I know that puts strain on the alternator too so the rest of you may be good past 100k.
