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've seen a few devs working on making the bluetooth Freedom Keyboard work on other forums on xda, but nothing here. Has anyone been able to get any bluetooth keyboard to work with this phone?
No, there are about 6 threads now on this same topic.
Our BT Stack blows monkey ballz, and is only good for BT Headsets w/o A2DP,
and its only somewhat ok with random headsets with A2DP. Other than that, OBEX, HID, Streaming Audio, IS all blow.
Why do I get zero results when I search "bluetooth keyboard"?

Android BT does suck ballz. Im sure in time that will get better. Outside of that, I love the OS.
Has anyone experienced trouble with a paired bluetooth headset & the NC? Whenever I try to listen to audio it stutters and when I try using the mic all I get is static for the first second and then the headset promptly disconnects. The NC says there is an audio problem but I don't know enough to get more info than that.
I've tested my headset to confirm it still works properly but am at a loss on how to improve the quality.
have the static problem plugging my earbuds into the audio jack. want even really aware the nook had blutooth.
Remember the range of BT with CM7 is currently measured in inches not feet move an inch past range and your sound stutters and dies..
Some folks say they get 2-3 feet in range, so far the best I have gotten with 3 differing BT headsets is about 7-8 inches and none of the microphones with them have worked.
Do we have an indication on whether this problem will be solved in the future? Finding a way to increase the range of BT (unless it is gimped by design) should be on top of the list by the developer community.
The possibility of allowing the Nook access to a blutooth microphone would possibly help make the device even better -- as it is its only main shortcoming.
I am able to connect to my car and use it to make and receive calls with no issues. When I attempt to stream music to the car it connects but the car will not let me switch to the phone audio to play the stream. I think it could be a bug with the ROM.
Anyone else able to use Bluetooth for music streaming in their car?
getting my One wednesday if my Best Buy rep was accurate, and BlueTooth music better work, that's what I always use for playback!
Using it with an HS3000 hard wired into my headunit for the audio profile while simultaneously connected to the headunit itself for the phone profile and its working fine. Perhaps theres a firmware update for the headunit in your car?
I'm not able to get it to see my Sony Automotive Bluetooth player but I haven't messed with it while not driving to really go in to it.

You are receiving the audio through the 3.5mm jack. My phone connects to the car and audio calls work great. I'm also having an issue with my TV. It shows connected but no audio plays, however when I press the volume on the phone it changes on the TV. I'm thinking something is missing or messed up in the ROM. I'm not sure if this is happening with other versions. It would be good to know.

Well your question seemed to be a question of bluetooth connectivity using the audio profile, so i gave you one example of when it does work for me. It doesn't matter that its outputting from the HS3000's 3.5mm in to a line in in my car, the audio gets to the dongle is the point i was getting at. Here are a few other things i have tested with it since i was curious as to whether this is a bug:
Moto S305, LG Tone, LG Tone+, Francois et Mimi Trois speaker, generic bt speaker i got as a door prize, and a samsung soundbar. Nobody can help you test whether there is a bug if there no information as to what you're trying to connect to other than "your car". As far as i know your car's bt protocols might be outdated and HTC left out some code for their BT drivers to work with older systems or if it is a genuine bug.
I appreciate your input, I thought you meant the cable was connected to your phone. It's wierd that I have a 2013 car and my EVO 4G LTE and an S4 both work but the new M8 doesn't.
I have no problem with streaming over BT to my car stereo or routing phone calls through it. I do have stuttering audio while streaming, however, which upsets me greatly.
I went back to the car and started messing around with settings and it now works. I had to disable and enable audio streaming. Audio is clean and crisp. Thanks for the feedback!

At times my audio will not come through. turning off BT in the car and turning it back on seems to allow the audio to work.....
I do however get the audio stuttering from time to time. Sounds like a CD skip almost. Yea I have been trying to figure out if there is a setting missing or something....most likely a bug though.....
Is the stuttering with all apps? I havent had much issue now but on my evolte i used ti get stutters whenever i transitioned towers or went screen off using gonemad and some flacs, poweramp seemed to be a bit better at it though.

Wow, not good. It's posts like these that help me to be more patient as I wait for my upgrade in July. Hopefully the little one like these are ironed out by that time.
I'm also getting random Bluetooth skips. Probably kernel related.

phone is not the issue here. Most smartphones have the capability to stream music over BT. The problem is usually when your car is setup to only handle calls over BT, nothing more. there's a workaround for this: You use Mono Bluetooth app in combination with your favorite music player app. It's not HD, but it works.

It seems my factory car stereo (which is only a year old) doesn't like the M8. I tried my 7 year old BT headphones and they streamed like champs. Stupid factory head units . I'm trying a couple of changes in audio_policy.conf to see if they make a difference. I don't think kernel is the issue here.

Does your radio have the ability to turn Bluetooth audio streaming on/off? That's what worked for me with my factory unit.

No.
Alright, fixed up my streaming issue. I'll explain later and post a fix. Busy right now.
So what I ended up doing was updating audio_policy.conf in /system/etc to allow lower bit rate audio over BT/A2DP. Currently the file only allows streaming at 48000, while some devices can only handle good ol' 44100. Adding in the additional value seems to have smoothed out my streaming for the most part.
I did notice some intermittent skipping when my device was in car mode and/or charging at first, but those issues seem to have sorted themselves out now. I would recommend deleting your device and re-pairing after making the change to ensure the connection is set properly.
I'll post up a flashable zip shortly to allow others to see if it helps/works for them.
EDIT: Zip attached. Sorry it took so long, Firefox was giving me problems.
@Captain_Throwback thanks bro, will give it a try. I've noticed it only to skip when using stock HTC media apps. Using Google Play music doesn't skip for me. May be a coincidence? Anyways, flashing your fix.

BT nightmares continue in Oreo, even after latest updates. BT keeps disconnecting from my BMW handsfree all the time. It used to be during audio playback only, but now it keeps disconnecting during the calls too. This is very serious for me since I am mostly talking in the car, and I almost crashed my car the other day while trying to keep conversation alive while BT was going up and down all the time.
What a great disappointment of a phone this turned out to be. I don't have time right now to export/import all my apps into another device, otherwise I would have ditched this crap long time ago.
This is a known issue with the Nokia 8. It also does this with my Apple Airpods where no other Android device does. A number of people on the Nokia Community are highlighting Bluetooth issues, as well as WiFi and NFC (and Android Pay).
TBH I have the Wifi problem, but not the bluetooth one.
And I use it a lot : JBL go speaker the morning, Plantronics backbeat pro 2 the evening, and Spotify through my Peugeot 208 car for 1h30 everyday. So I can't really complain, but I hope they are working on this issue.
So far, HMD proves to be good for security update, but I'm not sure they are really hearing consumers complaints: Wifi, bluetooth, mediocre camera app, APTX-HD not working, Glance screen...

They don’t seem too keen to actually reply to users, which concerns me.
Their social media feed seems to be full of photos taken on Nokias and retweets and links to people saying how great they are. Very little actual consumer interaction or reassurance.
Pretty unfortunate for a new startup like Nokia/HMD.

any fixes so far? I have problems with BMW Spotify and BT, too. BT music works fine, just the app connection with Spotify does not work. Sometimes i can only connect BT Music and Apps when i'm connected as the 2ndary and not primary phone.
Ive sent my Nokia 6.1 back as the bluetooth connections to my new JVC car stereo kept failing. Ended up buggering the radio bluetooth so have sent that back as well.Bought new Pioneer car stereo,wouldnt work with that either.My old Sony Z3 works perfectly.Another worrying issue is that since I sent the Nokia back,a lot of my devices now wont pair with my Sony,my Moto 360 watch doesnt recognize anything,my Tom Tom wont connect,and Im worried that the Nokia may have upset my new Pioneer car stereo
I'm using BT with a plenty of devices all the time
Pioneer car stereo
Cheap BT hands free from amazon
Yatour hands free in volvo
Bose headphones
Anker speaker
The only devices I'm having problem with is pioneer car stereo.
This makes me think that the problem is with pioneer unit, not the Nokia itself.
