Invalid [9.3.28] Bluetooth headphones not working on Mi8

[ivan.gulan]

Hello guys

I noticed this issue on two latest builds.
My Sony WI-C300 BT headphones connect to Mi8, but it won't reproduce any audio.
Also, when I try to shut them down, they seem to be unable to respond to any of my attempts.
I can work with them only when I get out of Mi 8 BT range.
When I connect them to any other Android or PC device, they work great.

Best regards,
Ivan

There's no way we can give any support for that. We don't have any Sony WI-C300 headphones lying around.

Same problem with Pioneer S3000BT car stereo. I need to restart bluetooth to make it work.

Mi9, 9.3.28

I ran across a BT test app that might be useful in seeing what is going on with BT connections.
(I don't have a Mi8 nor any Sony headphones.)

Seems the radio/headphones is trying to connect...
The only way is:
Put the phone in airplane mode
Turn on the radio/headphones and wait to power on
Quit airplane mode and turn on the Bluetooth
Now works perfect

Same problem redmi note6 pro on some bluetooth devices. Sometimes it connects sometimes doesn't. If i make pair from other device it connects. Some devices no sound when connected. I think driver problem about Xiaomi.
