Invalid Bluetooth bug

[SANUI]

Suddenly no audio at all when mobile is connected via bluetooth to another device and videos play really laggy.Absolute volume in settings seem to flash repeatedly even when its turned off or on.
Tried everything from simply unpairing to changing BT settings or resetting bluetooth cache and reinstalling last MIUI update but nothing seems to work and the problem persists for the last couple days .
Any advice ?
Mi 11 lite
MIUI Global 14.02

@SANUI You are NOT using this CUSTOM ROM here, hence it can't be bug here. Please address to official Xiaomi forum.
