🎧 4 hours later: Native AROS on Apple M1: first sound over Bluetooth! The MacBook Air M1 running native AROS played music through AirPods Pro 4, clean sound. Everything was built in one session, from the chip up to the ear: • Apple Bluetooth chip (BCM4378): a new driver boots the controller (firmware, calibration, address) and can be reloaded live without rebooting. • AROS Bluetooth stack: made reliable on the M1's 8 cores, with several lock-ups fixed. • Bluetooth audio (A2DP): an SBC encoder, stream negotiation with the headset, and automatic resume when the headset pauses the stream. • AHI (AROS's audio system): a new "Bluetooth A2DP" mode, so any AHI application can play to the headset. Result: the AirPods paired (with on-screen code confirmation), and music is playing 😎
