Invalid Volume/Sound not playing over bluetooth device

[Eidenz]

Alright so I've had this issue since the last 2 Xiaomi.eu weekly updates, and it's still there on the latest 21.4.21:

When I connect a bluetooth speaker/headset/etc.., the sound is still being output from the phone's speaker.
I tried unpairing the device, using different sound/volume presets, using different apps, restarting the phone multiple times, enabling/disabling battery saver.. And doing all of this again after a new weekly update came out.

To keep it weird, the bluetooth device is correctly paired since I can control the sound volume using it, pause music/videos, anything a normal bluetooth speaker/headset can do when it's connected you know.
I might add that, quite rarely, it fixes itself and the sound will go back to output to the bluetooth device for some reason. And more often, it starts on bluetooth for like 5sec before reverting to phone's speaker (even though Android tells me it is currently outputing from bluetooth). Forcing bluetooth instead of "default" does not change anything.

And yes, I tried it with 3 different bluetooth devices which used to work flawlessly before the last two weekly updates (when we were still on 12.5 instead of 12.6 at least).


I'm using the Chinese Mi 11 with the latest 21.4.21 Xiaomi.eu weekly ROM.

Thanks for your help.

Just click the small icon on the bottom right corner of media notification and voilà

Nah

Nah

Go into the Bluetooth devices properties, is USE FOR MEDIA AUDIO enabled?
When you connect with music off, and then play it, does it behave the same as connecting while playing?
Also try to reset network settings

And wiping dalvik /cache

I forgot to mention it but yes, I went into the properties for each device I tried, media audio was enabled. Tried playing with the switch while music was playing, changing it then restarting the phone, etc.. Still the same problem.

And weirdly enough, when I do change the state of the "media audio" switch, it marks a quick pause just as it would normally do when changing these settings. But it keeps using the phone's speaker anyway.


Since I'm using a Mi 11, I can't wipe any kind of partition/cache (no TWRP yet). And I really don't want to go over the pain of factory reseting my phone.

Wow thanks! It actually worked!

Might have spoken a bit too soon, because it's back at doing it.

And this time, resetting won't fix it.
I really don't understand this bug as it seems completely random, I haven't touch any settings since that day though.

Update:
I didn't do a lot of testing as I don't own a lot of bluetooth devices, but so far it seems to only affect some TWS earphones (ex: my Redmi Airdots 2). Bluetooth works just fine on my car's speakers.
