I can connect with another Bluetooth devices such as Mouse, PS4 Controller, 8BitDo Controller. But devices that I cannot connect from my test such as Bluetooth Speaker, Bluetooth Headset, Nintendo Pro Controller, My android phone.
Then I create Ubuntu 22.10 and 23.04 USB stick and test on live boot everything work fine. I can connect all devices. And before I move to Ubuntu, I use Fedora 37 and Bluetooth work fine too!
After I investigate, I think that maybe It has some bug in BlueZ or linux-firmware package
in Ubuntu 22.04.
Here is some output from btmon when connect to speaker. After timeout, it will repeat disconnect and reconnect forever.

Any recommend finding out root cause or work around?
PS. I have another notebook that have intel Wi-Fi card, but it works right OOTB.
PS2. I think my card is Atheros QCNFA725. IDK why it show Atheros QCNFA765.
