Can anybody tell me what is causing this sound? No cel, increases with rpm

Also wanted to mention that If you have ever had a bad stereo hook up and gotten that alternator whine sound where the pitch of the sound changes with RPMs that's kinda what I also hear in the driver seat at the same time im getting the noise from the engine bay... however no charging issues or CEL anything?

Poked around with that stethoscope yet?

I did about an hour ago, but couldn't really pin point if anything sounded abnormal. I didn't really spend much time as I was on my way out and it was dark but gonna try to spend more time on tomorrow with some daylight as I couldn't get to the pullies on the bottom/front of the engine.

Get you a 15mm socket and pull the splash guard so you can poke around better.

New belt, new tensioner assembly, new idler pulley and still getting the sound smdh. Gonna go ahead and throw another $48 and replace the AC belt and tensioner because why not at this point. Going in for oil change next week so maybe my mechanic can identify it if the AC belt and tensioner don't resolve the problem.

My a/c compressor makes a similar noise, just not as loud as that
