@ -28,6 +28,7 @@ AVRCP: `AVRCP_SUBEVENT_OPERATION` emitted for button release
### Fixed
HCI: handle start inquiry failure
AVRCP Target: fix notification changed event
HFP: Emit Audio Connection Released on SLC Release, e.g. remote power off
### Changed
HCI: config I2S for BCM Controllers if `ENABLE_SCO_OVER_PCM`, reduce bit clock to 256/512 kHz
