No Sound With Bluetooth Headphones - Xiaomi Mi Mix 2 Questions & Answers

ROM: LineageOS version: 14.1-20171012-UNOFFICIAL-chiron
Headphones: BeatsX
Everything except media sound is functioning properly, that includes:
Bidirectional phone calls (microphone is working and I'm able to hear the other side)
Media controls (play/pause, next/prev, activating Google Assistant)
The headphones are 100% working and tested on another device (OnePlus One with Cyanogen OS 13.1.2).

[Q] Bluetooth in-call audio not working - Galaxy S

Hi,
I'm unable to get in-call audio working with my Galaxy S (GT-I9000). I have tried Jabra BT3030 and Nokia BH-606 units but with both headsets I only hear a slight pop when placing a call and quiet hiss that stops when the call ends. I have tried the following steps to no avail:
- disconnected and unpaired the headset from the phone's bluetooth settings. Re-paired the phone with the headset but this didn't solve the problem.
- upgraded my phone firmware to version 2.3.4 (XXJVP) - I'm using Voodoo lagfix (just lagfix, no sound enhancements) on top of the base rom but it shouldn't matter?
I can listen to music with the BT3030 headset so the phone's BT functions are not completely dead... Any ideas what to try next to get calls working too?

Not Work Bluetooth Protocols: HFP, HSP

I use this headphones + CyanogenMOD 7.1, but not work microphone/audio if call my friends.
- Work listening music
- Not work listening audio and speak if call. Bluetooth button is disabled on calls.
WARNING: Microphone and audio work: i use it on my archlinux (linux distro).
BeeWi use this protocols: HFP, HSP, A2DP, AVRCP
HFP, HSP is disabled/unsupported on kernel?
I have the same issue with my HTC Desire with AKG K830BT headphones.
I tried different ROMs both GB and ICS (even stock). I currently use latest MIUI
Audio playback (Music) works.
In phone calls i cannot hear the other side, and the other side cannot hear me.
Please let me know if there is anything i can check to assist with solving this.
It's ok guys. Today is Oct 4 2014. I have Wildfire S powered with CM 10. Problems are exactly same - i can't use BT headsets and car BT handsfree units to make/answer calls 'cause sound is jammed I think CM developers are not like BT headsets.
There is information
"HSP logic is not implemented anywhere at the moment. The idea is to create another daemon to do so, since none of the projects already involved (BlueZ, oFono and PulseAudio) thinks that logic bits fits into its role. "
I think it is free soft idea grand fail .

[Q] Headset with microphone and buttons not working

Hi!
I flashed my Xperia S with a couple of CM based ROMs (CM9 and CM12) and none of them detect my headset with microphone and buttons.
When I connect the headset to the jack it keeps playing whatever it is playing on the loudspeaker instead of re-routing the sound to the headset.
It must be something specific to the microphone + buttons because when I use normal headphones without a microphone it just works as expected.
The stock firmware would display a dialog with "The accessory's microphone and buttons are not available." but then the headphone would work normally as expected.
Is there anything that I'm missing?

No ringtone on bluetooth

I have a OnePlus 3T running Lineage 17.1 When connected to a bluetooth headset or the car audio system the ringtone is so quiet as to be almost inaudible. Ringtone only comes from the phone speakers. Any suggestions?

Question LineageOS all audio plays through speaker

Hello,
I installed Andy Yan's lineage OS 18.1 treble_arm64_bv build on my phone, and everything appears to work fine, except audio always plays through the speaker, even with wired or bluetooth headphones connected. The headphones connect, and the volume control shows bluetooth, but then plays out the speaker. Bluetooth works fine in other cases - bluetooth tethering to share internet works.
Any ideas what I can do to fix this?
