Bluetooth Headphones Play/Pause Buttons - Verizon LG G3

My setup:
VS985 with CM13 nightlies (both clean install & dirty flash to most recent version; update on a daily basis and check if Bluetooth issue is fixed; no fix yet)
35B bootstack
Platronics BackBeat Fit headphones
Current issue: the "Play/Pause" button does not work as expected. Pressing the "Play/Pause" button does not toggle Play/Pause. Upon pressing the button, the music DOES get interrupted to the headphones for approx 1-2 seconds, but the track keeps playing behind the silence. Pressing the other functional Bluetooth button on the headset properly initiates the Google voice dial/launcher.
As a test to make sure it wasn't an issue with the headphones, I connected them to other devices (such as my Windows 10 laptop) and pressing "Play/Pause" on the headphones does toggle "Play/Pause" as expected.
Is this an expected/known issue with the CM13 ROM? with the bootstack? with the LG G3?
Is there an app/patch/configuration file I can modify to dictate the desired actions when pressing the Play/Pause button?

I installed the 777 Kernel last night and tried to use the Play/Pause button this morning. To my surprise, the music in the Google Music app stopped playing and the Spotify app began playing (it was previously closed, so it both opened and started playing).
This is leading me in the direction of believing that the solution is in the kernel, considering 35B & 777 kernels act differently. After a few searches I found a kernel command keycode_media_play_pause that - I believe (with very little programming knowledge) - controls the inputs from bluetooth devices.
Anyone think I'm on the right track or have any suggestions?

Completely wiped my device and clean installed 35B bootstack, 20160108 CM 13 nightly & Open Gapps Pico.
On first boot & pairing headphones, Play/Pause works perfectly!
I tested the headphones after installing each app and my problem came back after installing Stitcher Radio for Podcasts. This kind of makes sense as it is another media-playing app which might compete for Bluetooth's attention.
-Uninstalling Stitcher Radio leaves the issue behind.
-Clearing the cache/dalvik does not fix the problem.
-Dirty flashing the nightly again does not repair the problem.
Sounds like I would need to do a full wipe again to regain my bluetooth headphone functionality.
Any thoughts on what is happening when I install the second media app? Any suggestions on how to repair the link between the "Music" app and my headphones?

[Q] Bluetooth to Car Stereo Media Controls

Hi,
I'm running Comm Rom 2.0 with the MIUI music app. I can connect my music to my stereo via bluetooth with no problems, but I can't switch tracks using the stereo controls. My sister has a stock, unrooted Fascinate and the controls are responsive for hers. I've also tried using the default music player and that didn't seem to change things on my end. Other threads with different phones on the matter don't seem to have any definitive solutions either. I'd really appreciate it if someone had an idea of what's going on with my phone. Thanks.
My MIUI music lockscreen (next/previous) controls aren't working either. Pause toggle works fine though. Also tried simulating Next and Previous Media buttons with Tasker and that's unresponsive too while pause is fine.
I tried restoring nandroid to when I remember it working but it doesn't look like its changed anything. Is something conflicting with something?
My phone was overheating and locking up while using bluetooth. I plan on trying it again with my latest rom. I will check and see if I can switch tracks.
Thanks, let me know how it turns out.
I guess I should probably rephrase the question. Has anyone running Comm Rom 2.1 with or without MIUI have trouble switching tracks via universal media buttons with lockscreen or external controls?
check out this app: Media Button Router (https://play.google.com/store/apps/d...cm9pZC5tYnIiXQ..)
that should fix it
Link isn't working... but more importantly did you realize this thread is almost 2 years old now? It's more than likely he's resolved it by now...

[Q] Bluetooth disconnect/sleep on lock screen [PowerAmp] [SOLVED!!]

Hi,
I m using ROM AdyScorpiusMIUI-GB[2.3.7].
However I have a few issues and the main one I have not manage to solve is related to disconnection of my Bluetooth headsets when the lock screen is active or being idle for a minute. I dont whether its because of software (MIUI/kernel/baseband) issue or hardware malfunction issue.
I have tried to search for it but have not found any info. If I missed some thread then feel free to direct me to it.
Symptoms;
Headset disconnects when screen goes black.
Turning on the screen (so you see the lock screen) turns Bluetooth on.
Phone;
Galaxy S2
I have tried the following kernel versions;
Androdi : 2.3.7
Baseband : I9100XXKP8
Kernel : 2.6.35.14-Siyah-v2.6.12+
MIUI : 2.2.3
Bluetooth devices;
Nokia BH-503
I hope there is something that can solve this issue or that I just missed some setting since I really like MIUI,
Best regards,
Sauky
For those who has the same problem with me.
Here is the solution :
Problem occurred when im using PowerAmp with Bluetooth Headset in CM7 based Kernel or Custom ROM.
And the solution is :
- Do The "Clear Data" for PowerAmp Application
- Do The "Clear Cache" for PowerAmp Application
Menu (Setting->Program->Manage Applications)
Addes solution here :
Using an application like Wake Lock (hxxps://market.android.com/details?id=eu.thedarken.wl) and starting a service to wakelock the phone 'resolves' the problem on both Stable and Nightly roms.
From (hxxp://code.google.com/p/cyanogenmod/issues/detail?id=4794):
after some research it seems that poweramp doesn't explicitly start a partial wake lock when playing music.
Poweramp uses the AudioTrack class. reading through the api specs it doesn't seem that this class has a method to hold a partial wake lock (or even if it should do it automatically)
It appears that poweramp relies on drivers (possibly the audio driver) on the phone to hold a partial wake lock when music is playing. while that is true for lots of platforms (including samsung using the original firmare and many others) it doesn't seem to be true to whichever audio driver cyanogenmod is using.
I guess there would be two possible solutions, either this wakelock is implemented within cyanogenmod when music is playing or poweramp wakelocks when its playing music and releases when its done.
I seem to be having the same problem with my Bluetooth. But I have the problem when using a Bluetooth headset while making a phone call. The headset just disconnects about 5 min. into the call.
I'm running CM 7.1 and have power amp installed. Clearing the cache and data settings for power amp did not solve the problem. Inevitably about 5 to 6 min. into the call my Bluetooth just disconnects and I have to hurry and pick up the phone turn Bluetooth off and continue the conversation on the handset.
I really like the CM & MIUI ROMs, but this is a dealbreaker for me. I love power amp too much, and I need blue tooth. I guess I'll have to go back to one of the stock-based ROMs

I have no issue with a phone call so far.
Have u tried installed and running "Wake Lock" above from market? (hxxps://market.android.com/details?id=eu.thedarken.wl)

Bluetooth Media Volume Issue

I have this odd issues related to Bluetooth on my phone. The head unit in my car speaks A2DP. When I turn the car off and the bluetooth disconnects the phone always mutes my media volume. There's a secondary issue where it occasionally takes my phone out of vibrate mode but haven't pinned down how to recreate that one yet.
Had anyone experienced either of these issues and/or know of a fix?
What I'm running:
I recently reflashed my phone to stock 2.3.4 and let it OTA update to 2.3.5. After the OTA I did a full wipe of data/cache with CWM to start from a clean slate.
I do have AutomateIt Pro and specifically have some triggers setup for the cardock (not BT just cardock) but I disabled AutomateIt completely and tested before posting here (this was my 1st thought).
Thanks
Chris
I think that is a feature of Android, like if you were blasting death metal, the next time you use it you wouldn't be blasting it again and be surprised.
I see where it is a pain in the butt. Have you torn through the BT settings?
I have and I can't find anything. Today I discovered that it also does this when I unplug headphones as well. (I don't often use headphones with my phone).

[Q] Google Navigation keeps turning media volume down

Hey, everyone! This is my first post here, so be gentle.
I'm having some trouble with Google Navigation on my SGS3 from US Cellular. Now, I understand that the volume has been merged together with the media volume, and that's not really my issue.
When I enter Google Navigation, the media volume reads correctly. (I jacked it up to full volume just to test this out. It reads full volume when I start GN.) But when a turn-by-turn direction reads, the volume is really low. If I hit the volume up button during the TTS directions, it shows that the media volume is set very low. I can turn it up while the direction is speaking, and the media volume does increase. But the next time a direction begins saying something, it's quiet and the volume is reset really low again. I have to keep turning the volume up for each turn-by-turn direction!
When I exit GN, the media volume is back to full blast again, just as it was before I entered the app. So, it's obviously something GN is doing. I just don't get why it won't remember my volume setting when I turn it up.
Any ideas as to why it's doing this? Any thoughts on how to fix this issue? I did a bunch of searching and couldn't find anything that completely fits my problem description.
ETA: I tested this again, and it's only a problem if I have a media player fired up. I use n7. When it kills the volume for the media player, it does so for the navigation, too.
Unfortunately, even if I close n7, the volume is still ruined until I stop and restart my Bluetooth connection. If I start Bluetooth and run navigation without the media player, tts works fine.
Apparently the audio issue where it keeps turning my volume down is only when it's not connected to Bluetooth in my car.
do you even use google navigation? if not just disable it in setings

Well, it's difficult to use it when Navigation keeps messing up my audio. The phone is still pretty new to me. I just got it in January. I'd like to use it as my GPS, but I'm not going to go for a long drive without playing any music in my car. And I'm not going to just use GN anyway, when I'm likely to blow past my next turn because the audio directions don't work properly.
Why would I bother to ask the question if I don't use (or, in this case, want to use) Navigation? It's like you're implying that I'm asking about something I won't bother using anyway.
My workaround for this issue
I have the same issue; both music and nav volume drops during voice turn by turn instructions. I found the media volume is being turned from full to half during the nav/voice output. I use Volume Ace and it has a feature to "lock media volume". I check this box and now when a turn by turn instruction plays the nav/voice speaks at full volume (the media volume setting is no longer reduced to half during voice output) though the music is also playing at full volume in the background. Hope this helps.

That helps a lot. Thanks! I'll have to give this a try and see if it works on my phone.
Do you have to set the media volume lock each time you want to use the GPS? Seems like you'd need to turn it on/off only when you need to use the Navigation app.
Yes i have to turn the media lock on for gps and off for normal use. Its a hack for sure but at least i can hear the gPS voice prompts for now until Google fixes the maps app. Good luck.

Has anybody actually found a proper solution to this problem? I am having exactly the same issue on my new HTC one GE. If I pair my phone to my car via Bluetooth and use Copilot (navigation app) while playing music through the stock play music app, every time there's a voice prompt from copilot the music volume fades down, as it should, but then it doesn't automatically come back up when the prompt ends. I have to manually increase the volume which is both annoying and dangerous. To me it seems something rather simple to do but according to Copilot's customer support it entirely depends on my phone's capabilities, whatever that means. I know that I'll get a lot of grief by saying this, but my iPhone 4 could do this no problem.

I just stopped using my n7 media player and switched to Pandora radio. Pandora doesn't have this issue. It must have a separate volume control built into the app.

Bluetooth: no track info and external control if display is off

Sinced I'm switched from my Nexus 5 to the Elephone P9000 I'm having following issues with two different car audio systems and also with the Stock and Eragon ROM:
Connecting my phone with the car works fine and it also playing audio, but I don't receive any track info (artist, song, etc.) when I use Spotify at the car audio system and I'm only able to skip/pause/start songs from the car audio system if the display of the smartphone is on.
I tried to find any settings but nothing worked...
Does anyone having the same issues or solved it?
I have the same isssue with both Bluetooth devices and plugged in headphones. Buttons for song control only work when screen is turned on.
This seems to be an OS issue. Hopefully they get it fixed with Nougat
No Issues like yours, here. Just Stange behaviour at the beginning of a track, that is played faster (2-5 seconds).
For track Infos try the App "autoaudio" helped me with my G2 Back then.
