The other person's voice is muffled and difficult to hear

I bought a new computer and updated it to Windows 11. It works fine for listening to music and making calls online. However, with Zoom, I can hear the other person's voice, but I can't hear what they're saying. I have the noise canceling turned down, and the speaker settings are not up to snuff. What should I do? I can hear with Bluetooth earphones, but wired earphones and the built-in speaker make for a perfect meeting experience.
