BT earbud connection issue

Hi all
T95 Max + 4/32 CE 9.2 nightly / Matrix nightly and Rc2
I just buy this Umidigi Earbuds (https://community.umidigi.com/portal.php?mod=view&aid=510 ) and I can connect them to 9.2 CE ng or Matrix. I see them “connected” in CE when I power them but I have no sound and I have to disconnect and reconnect them in CE BT profile first before to get “really” connected where Its supposed to be connected automatically …

I have to do this before to use this BT earbuds and each time I want to use it.

I have to do this with another earbud which work good before too…

I tried to delete them in CE BT profile with a reboot and enable them but its the same…

I want to be clear as I can I see My BT get connected in CE BT device list when I power my earbud but I get no sound I have to disconnect and reconnect manually in CE device list to get sound.

There is my log 9.2 http://ix.io/3rVp
Matrix nightly http://ix.io/3sTF

I’m looking to do a full RESET of the CE config BT file but I don’t know where its located and I would’nt reinstall full fresh build to retrieve the BT use its too frustrating…

So any clue welcome !

Thx
