Having Bluetooth "Handsfree" and A2DP connected at same time causing severe skipping
Hi....I know there are a lot of posts regarding skipping while playing MP3s over A2DP. My problem is perhaps a little bit different because I've narrowed my problem down to the handsfree bluetooth service.
Here's my situation with my unlocked HTC TyTN II using the stock HTC ROM and with no registiry modifications (bitpool, etc)
If I have only A2DP connected and streaming music to an external bluetooth receiver the MP3 playback is flawless. It sounds fantastic. I've tried Windows Media Player, PocketMusic, and PocketPlayer and they all work just great.
However, when I turn on my handsfree headset (which is a separate device from my A2DP receiver) and allow it to connect to my TyTN II, extreme stuttering immediately occurs through the A2DP music stream. When I shut off my handsfree headset the stuttering stops and the music stream returns to its usual fantastic sound. The problem can be replicated also by leaving the handsfree headset powered ON and simply enabling handsfree service on the HTC TyTN II to cause the stuttering to begin. The stuttering stops immediately when handsfree service is subsequently disabled.
Anyone else out their experience this? Any suggestions? For the time being I have to resort to disabling handsfree when streaming music to my A2DP bluetooth receiver.
Skipping/Cutting out/Speeding Up/Slowing down
Not much to add other than 'Me Too!' and thanks for tracking this down since i thought i was going nuts since I've had a couple of times where i thought i had it resolved only for it to crop up again.
Are you also experiencing your A2DP audio speeding up and slowing down along with the audio cutting out? since to me that is the most bizarre of all of the audio freakery going on.
I found my Logitech handsfree less likely to cause cut outs when on than my Jawbone does. but neither were trouble free.
Just an update for those that may experience the same problem as me. I've noticed that sometimes I have perfect audio even though I am connected to my handsfree car system while streaming music via A2DP. So this leads me to believe that bitpool settings and such are not the issue...since the perfect audio can occur with the default settings. I have also heard in other threads that flashing a new radio may help...but haven't gone to that measure yet.
What I have been able to determine is that this horrible skipping/stuttering occurs when my phone is changing cell phone towers.
That is, if
1) Streaming audio over bluetooth via A2DP
AND
2) Tytn II also connected to a handsfree device
then A2DP skips horribly when the phone needs to switch cell towers.
I have confirmed this by using the program PhoneAlarm to log the cell phone towers my phone is connected to. My A2DP stuttering/skipping problem coincides with every change in cell phone tower.
Now having said all this there is still one other factor that plays into it that I haven't quite figured out. If I soft reset my device and then immediately connect to my car and A2DP stereo then I do not get the stuttering problem when changing cell phone towers. However if I spend the day using the device, active-syncing and such at work, then on the drive home I will ALWAYS get the stuttering during every cell phone tower hand-over.
Frustrating. Anyway...hopefully I'll eventually figure out the last piece of the puzzle. I would rather not have to soft reset every time I get in my car just so that I can get good audio.

I do recall getting this behaviour when using Windows Media player...but I have started using the new Pocket Player and have since never experienced the audio slow down problem.
I found a work-around that works for me. It's posted here:

I seem to have related but a different problem with skipping.
I have both Sony and goldlantern BT headphones which i tried (stereo profile).
Both severely skip audio when located on the left side of my belt. Silly but the reception/skipping problems improves a GREAT deal when i move it to the right side. It works flawlessly inside of the building where i have no phone signal but outside -- it skips horribly, even worse after 6.1rom upgrade.
Can anyone confirm that the BT signal going through the body worsens skipping? If so, I assume the signal strength/BT/wireless channel may be at fault, not the tower switching as for me, it happens even when I stay stationary.
Any help is GREATLY APPRECIATED!
TILT - R2 VEGA WM6.1 CE OS 5.2.19209 (Build 19209.1.0.2) ROM
I think part of the problem can be the A2DP device as well. I had a pair ofr HT 820 older bluetooth headsets with A2DP that were skipping and annoying. I went out and bought some s9s and the problem went away. I figured just for a test I would try the HT820 out again, still skipping. So for me it was not the phone but the A2DP device.

i thought that too but i have two different headsets from two different manufacturers, both are skipping the same...
A2DP requires a lot of the bandwidth Bluetooth can provide. Having a 2nd connection open simply exceeds what the Bluetooth chip can handle, no surprise in that. If the BT headset keeps the connection open it's very likely to happen.

what do you mean by a SECOND CONNECTION?
i have 2 different headsets because i thought that i have a poor headset, but both work similarly bad, which makes me think it is the tilt, not the headphones. i do not have 2 connections, never has it and not even sure if it is possible....
Lowering of bitrate did not help at all.....
Anyone have experienced these problems? anyone is using BT headset besides motorola s9?
On mine it does it when it picks up a wi-fi hotspot. When I'm driving the wi-fi is on when the screen is and whenever I pass a hot spot it drops out. Turning the wi-fi off solved it. Don't know if it does it with cell towers.

The thread was initially about skipping when BOTH an A2DP stereo headset AND a BT handsfree were connected at the same time, as the title shows. I was commenting on that.
Other than this, when I want to listen to music I can leave the Kaiser in my room and walk around in my entire flat with the headphones on without skipping (around 10-15m straight line, with some walls).
However, Wifi must not be active and communicating, otherwise either / both of them will drop. If I'm using Wifi and start streaming audio via A2DP, the wifi will slow down a lot and sometimes disconnect. In the same way if Wifi is communicating the audio will skip. If both of them are active but one is idle everything's fine. But that's also normal as both share the same frequencies and will step on each other. When usage is low it's not noticeable but when both are using a lot of bandwidth then they will disturb each other.
The cell radio doesn't seem to cause any problems for me.
I bought a HomeSpot Bluetooth receiver to play audio from my One through my computer speakers. There's a delay that chops off about a second of the audio when it connects. Once the connection is made there are no issues and it will play fine until the phone stops sending data for some reason. Then it disconnects instantly. For example, if I pause the music app the phone terminates the connection and when I unpause it will skip.
Is there a way to keep the connection alive permanently? I only use Bluetooth at home when the phone is plugged in, so I'm not worried about battery drain.
Anyone know if this is possible?
Hello Everyone,
I'm having this issue for some time and was trying to solve by myself but my resources are done.
Scenario: OP3T 128Gb OOS 4.0.2 (no root) playing music using Spotify on a car Bluetooth device (Toyota Corolla - picture of the stereo attached).
Problem: Audio cuts during play. I can also listen some noise indicating problems on audio transmission. Iá attaching a 1 song recorded in the car where is possible to listen the audio cutting some times during just one minute. It's impossible to listen music with this problem. So annoying.
No problems listening to music on other bluetooth devices like earphones or a audio totem. No problems listening using audio jack.
Workaround: When I do a Network Setting Reset the problem goes for a while, normally for a day. The problem come back after some time and I need to reset network settings again. I'm basically resetting network settings every day.
My wife's iPhone plays without any issue. I had a Moto X Style (Pure) before and I had this problema after flash some CM13 based ROMs, solved by flashing the original fw some times. (Moto X Style have some problems and if u flash modem and other thing once it won't work)
Anyone else had this kind of problems? So I need some help to figure out what is happening.
HELP!!!!!
Well, my bluetooth connection is stable. But sometimes when connecting to my car's bluetooth it starts playing music through the phones speaker instead of transmitting it to the car. I have to disable and enable it again - kinda annoying when the party is in your lap, at least while driving in a car.
Hi guys,
I have a pair of Apple Airpods running on the latest Lineage OS on the Mi5. Problem is the bluetooth is very weak. It doesn't disconnect however if playing songs through Spotify for example the audio will drop out. Usually deteriorates and then drops out completely. It's still connected, however to fix it I have to disconnect and reconnect again. Very frustrating. Any ideas as to why its doing this.
I've just bought the Play - and it auto-upgraded during setup so I'm now on Android Pie.
I have noticed that bluetooth audio "stops" and restarts - with audible glitches every 30 seconds or so if Wifi is enabled. If I disable Wifi then the audio is perfect (well - not glitchy)
Data source is downloaded (audio book) so it isn't a streaming issue.
Also - if I stream Netflix and use the phone speaker - all works fine. If I stream Netflix and have bluetooth headphones on - I get buffering.
Anyone else noticed this / got a work around for this problem?
I just tested this with my Honor Play running Android Pie. With bluetooth headphones along with WiFi, there were no skips or glitches with the audio. Might be an issue with your headset or something.
I use Netflix with JBL BT speaker or Bluedio T4 BT headphones. Works perfectly.
Thanks for the responses. Odd that I didn't get this issue with this headset and my previous phone (Galaxy S7). Thanks for confirming it is isn't a problem with Android 9.
What type of headphones do you use? Which manufacturer?
