Hello everyone. I have a 5t oneplus with still the bootloader locked and recovery stock. I arrived with nougat and after an update via OTA I am on oxigenos 5.0.4 Oreo. I'm having serious problems with pairing my Bluetooth devices !! the bluetooth phone sees them, but when I try to pair them, the password or unrecognized pin appears. bluetooth is essential for me, I use it for work. can I perform this procedure with the tool in question, with the bootloader blocked and the recovery of the stock? I am convinced that it is Oreo who gives these problems with bluetooth! maybe coming back to nougat I solve. sorry for my bad english, I use Google translator!
Can someone help me please?
My cell phone does not sound or even in the microphone.
Microphone is muted.
I plugged in my JBL Bluetooth headset, and it was also without audio and microphone. I restarted the phone, with the JBL turned on via Bluetooth, the phone's sound came back, but the microphone didn't.
If I restart again, without JBL connected via bluetooth, the problem of no audio comes back, and the microphone is not sounding.
I think the problem has to do with software, not hardware.
In view, I often restart the phone, and sometimes come back.
Just yesterday, I restarted the phone, and out of nowhere, the microphone and the audio came back. It lasted a day, and it got bad again.
The headset by the type C adapter also does not recognize in the phone.
I put the headset on, the headset icon does not appear on the taskbar, let alone sound on the headset or microphone.
Is it a MIUI bug? Should I keep flashing Miui through Xiaomi Flash until the bug goes away?
My current MIUI is Miui Global 10.4.1 (10.4.1.0) PCAMIXM.

Probably a bug with your firmware.
Try to do a clean install of the rom or a factory reset to the phone.
I had a bug with my Wi-Fi with my Mi6 for over a year. Between Global stable, xiaomi eu beta and STABLE, my wifi was always dropping, sometimes more than others. Now it's fix. Probably magic.
I had problems with xiaomi roms that what fixed it was flashing the same zip over and over again until it started working. Not even flashing the phone back to stock fixed it.
Always backup your stuff before doing a factory reset.

I just reset it, still nothing, turned the microphone back on once the ROM installation was over, and then the microphone is muted again.
I upgraded from the phone itself, in the system update tab, and located the internal memory.
I don't know if so, the installation is less clean, is it?
For Xiaomi Mi Flash, it only works if Xiaomi has the bootloader unlocked, mine is locked.
To unlock the bootloader, also only if it's in developer ROM, I was in stable.
What do you think?
Now I'm in the developer ROM, better unlock the bootloader, and try to re-rom via Xiaomi Mi Flash or install TWRP, and go there?
Will this make the installation cleaner?
I am still confident that the problem is firmware, not hardware really.
The newest vantom kernel might be the cause?

I was thinking this, I'll pass this kernel to see what happens:

How did you do ? I'm stuck in the same situation. I have tried to flash stock rom, flash another rom, but still no sound and no microphone

Friend, I couldn't solve it so far. I do not know what else to do!
Already blinked stock rom, both by twrp, both by Xiaomi Flash. I installed Line OS rom, thinking that maybe out of stock could solve, and nothing.
And so far, I don't know if the problem really is software or hardware.
Thinking it was hardware, I bought the charging plate that comes with the microphone capsule days ago, I changed the part, thinking it could be the capsule, but the problem still persists.

How did your problem start?
Do you remember?
My, I do not even remember how it started, I already have this problem, a few months ago.
I tried to contact Xiaomi Global too, to no avail, they only recommended I do, what I had already done, factory reset, and etc ...

It would be nice if someone else, experienced in Xiaomi phones and the firmware / software issues of the phone, could help us.
I don't think people see much of the help tab topics around here.
I'm thinking of sending a private message to members who always post rom's here on XDA.
Can you solve the problems you encountered? I also encountered the same problem as you.
I know this thread is bit old, just to try to give some piece of mind for the ones searching out there (like me)
I have not solved the problem, there is no audio output in anyway, neither the microphone works.
After long time i taken my Xiaomi Mi 6 and flashed Lineage OS on it (lineage-19.1-20221013-nightly-sagit-signed) and using adb logcat to check the logstream from the device, i get the following messages:
11-09 00:04:35.233 28971 29014 E AudioSystem-JNI: AudioSystem::listAudioPorts error -19
11-09 00:04:35.233 28971 29014 W AudioManager: updateAudioPortCache: listAudioPorts failed

This lines repeat a lot of times, so I dig into Android Code Search to checkout what is the -19 code. Per def in the source code, -19 is the ENODEV constant, saying "/* No such device */".
As this constant is used everywhere in the source code, I need more time to isolate and found out where this error relates to the Audio System.
I still can't determine if it's a software problem or a reporting from the software that the hardware is faulty. I will update this message as i discover more.

Have you found anything? I'm having the same problem, is it actually a hardware issue or is it software?
