Here’s a clear, step-by-step write-up you can use or adapt for a guide, help article, or internal documentation. Hands-Free Telephony (HFP) is a Bluetooth profile that allows a device (like a car, headset, or speaker) to handle phone calls. Sometimes, enabling this profile on a computer or phone can cause audio issues (e.g., poor sound quality on headphones, microphone not working correctly, or calls taking over your speakers). Disabling it prevents the device from being used for calls while keeping it available for media audio (music, videos).
