Strange sound coming from serpentine belt area

Hi , brand new to Tacoma world. I'm the mornings my car has been making a squeaking sound so I replaced the serpentine belt , and it's still making the same sound . It's definetly coming from that general area , if someone could help me out in identifying the issue that would be great. I put a link to a Video of the sound. Thanks. Ty

Take you belt off and check all your pulleys and water pump.

When was the last time you changed your water pump?

 

The belt tensioner looks like it's jumping around. May be time for a new one.

 

Possibly your ac compressor pulley, bearings went bad. I had to replace mine, sounded like metal grinding against each other.
