I think the new Sonoma update affects low audio on their built in speakers for some users

I’ve seen some people like me who experienced low audio on their built in speakers since the we updated to the new Sonoma version on our MBPs. Like when I put the volume in half, it sounds pretty soft and barely hear anything. I have tried booting to Safe Mode if it can work but it doesn’t. Rebooting my Mac and Core Audio doesn’t work either. Other methods doesn’t work as well.

I can’t tell if it it’s the software issue, hardware issue or a bug but this is the issue that should be fixed. I just want my sound back. What yall think what’s the issue?
