Why does Bluetooth audio sound... Note

Why does Bluetooth audio sound terrible after connecting to Windows 10?

Why does my Bluetooth speaker sound fine when paired to my phone but muffled and distorted when connected to my Windows 10 PC? Why does the audio quality drop even further the moment I open an app that uses the microphone, like Discord or Zoom? Could this be related to the Hands-Free Profile taking over instead of the Stereo profile, a driver issue, or a codec setting I need to change? And is there a fix that keeps the sound quality high while still letting me use the mic?
