After 2 days of digging through forums, testing kernel parameters, and trying multiple distros, I finally eliminated the infuriating audio stutter on my setup. Posting this here so others don't have to suffer through the same trial and error.

Hardware:

HP Pavilion 14‑dv1xxx

Realtek RTL8822CE Wi‑Fi/Bluetooth combo card

Sonos Roam (Bluetooth speaker)
