Upgraded from macOS 12 to Sonoma through OCLP and everything is great except the speakers

Hello there

I have an A1502 (2015 macbook pro 13 inch) and I had it upgraded to Sonoma

everything has went smoothly and I’ve done the after-install patch thing but my speakers have been f’d up. They still work but they sound veryyyyy distorted and different than how they used to be. What could be the possible reason for this and how would I go about fixing this ?
