Hello I started having this problem a week ago, need some help please!

Redmi Note 9s-MIUI 12.5.5

My bluetooth doesn´t work with any devices (there is conection but not sound).

The option \_Absolute Volumen\_ Blinks every time when you start playing something but the sound does not comes out. Also other apps like spotify and Yt starts to work slow or the music timeline bugs.

Things that already try.

\-Factory reboot.

\-Changing region.

\-Disable abs Volume in bluetooth options for each device that i tried

\-Clean bluetooth cache or data.

\-Clean all device paired

\-Reset bluetooth options in th developer options (also trying diferents presets or codecs)

\-Disconect an reconect diferents devices its always the same.
