Bluetooth problems

Hey guys,
I have recently started to experience some weird bluetooth problems. I have a Softbank HTC Desire (I live in Japan) and a LBT-AR200C2 bluetooth receiver. I had absolutely no problems whatsoever the first two weeks.
Yesterday, the bluetooth receiver would connect but no audio would play through the headphones. When playing a track from the player it would just skip over in 2-3 second increments and no audio was present (not even from the phone speakers). Not even reboot helped.
So, I decided to unpair and pair again to try and eliminate the problem. Everything is working now ... except for one big problem - the bluetooth disconnects every 3-4 mins. So, I start listening to a track, the screen goes to sleep and 2 mins later the music stops and Bluetooth disconnects. I unlock the phone and the Bluetooth reconnects immediately.
Besides the HTC Music Player i Have 3 and Museek installed. Could that be a problem?
Update: Listening to music without the Bluetooth receiver is ok - the music does not stop.

I seem to be getting exactly the same problem with my car kit.
I can pair it up, both car kit and Desire recognise that they are paired yet after approx 2 / 3 minutes it disconnects yet as the above poster indicates - it worked flawlessly for about 2 weeks.
I have deleted all the pairings, reset both the car kit and the desire back to Factory defaults but the problem happens straight away.
Googling desire and bluetooth seems to throw up a number of potential issues so was wondering if anybody out there had similar problems and whether anybody actually has a work around
cheers

Same issue with my Motorola HT820 headphones. Drop calls back to the handset and get silent periods when listening to music.

Gap & silent during listen music

-when listen music either on HTC music widget or PowerAmp
- got Gap and silent when using Bluetooth headset
- works fine if direct connect to the ONE X
any idea and fix ???

I've yet to see if this works for bluetooth but had a look at the ROMeOS rom and saw this in the build.prop as monx seams to have fixed the stutter: lpa.decode=true
I've set this in my build.prop and will try through the car bluetooth tomorrow.
To edit build.prop in the system folder you will need root access

thanks , buddy , let me know the result.

Unfortunately made no difference for me, will keep digging though as this is annoying when I have a 40 min commute to work each morning and again back.
Anyone have any idea's?
Edit: this doesn't just happen on the beats setting, turning it off makes no difference.

Anyone have any ideas on any fixes yet?

Have the same stutter issue even after 1.28 update connected with my bluetooth MW600.
Seems the problem is device switching to power conserve core. When i play music in background while running GPS in foreground, iam not getting the stutter.

That seams to be the case, having just sat in my car for 15 mins, 5 mins just music and 10 mins with music and maps and no glitches with maps.

I have the same bluetooth headset, the MW600 and the stutter makes it unusable. I'm on 1.29 stock now and I got to the point that I don't use my MW600 for listening to music anymore, but just wired Sennheisers.
Have you found a solution yet?

No. Not really
After using MW600 for 2+ yrs without much issues iam thinking to order Sony Smart wireless Headset Pro and see if it makes some difference. But, its not yet available in stock

I read somewhere that some custom ROMs solve music stutter issue. Iam on stock locked and can't comment though.

I was also planning on buying that Sony thing, but then I found my Nokia BH 214 back. It is now charging and when I'm back home I will test it. If it also stutters, I'm not going to buy a new headset, because it's likely to have the same problems, although that Sony is Bluetooth 3.0, which could make a difference.
I'll let you know the results with the Nokia.

I have stutter problem with sennheiser Bluetooth headphones. Am on stock 1.28, and disabling beats doesn't help (although did help on older version)
Music is unlistenable now

I'm running 1.28 & have the same issue with my car kit which is a works supplied Nokia car kit that allows A2DP connections. I'm definitely going to try running the GPS at the same time on my way home from work to see it that fixes it as suggested. I have a usb charger that I plug in so won't be using any extra juice. I'll post back my results.

Sorry for the very late reply, I completely forgot it. Just yet I tested the Nokia BH 214. First my One X couldn't find it, tried for almost 10 minutes. Then I disabled WiFi, just to try, and yes the headset was found. Then I put WiFi back on, but it refused to communicate. Wifi off again, communicating worked. So to say pairing was easy: far from that.
Now the next phase: listening to music. Completely unusable. Very very bad. There's something wrong with output, vocals are washed away and sound like the singer is 100 miles away. While quality isn't an issue with the MW600. But also the gaps. What is also very strange is when the phone is on my desk in line of sight with my headset, the are only a few gaps. But as soon as I put the phone in my pocket, the gaps increase exponentially.
So I think in my case the only thing left is to send the phone back. There must be something wrong with it, my WiFi reception is also very bad. Bluetooth also sucks, so since WiFi and Bluetooth are handled by the same chip, there must be something wrong with it. I really like the phone and sending it back means it's away for 2/3/? weeks, but first I hoped it was something with the software but that hope is fading away.
--------edit: just pissed of by all this. Called HTC and I'm sending it back for repair. Nice phone, but basics like WiFi and Bluetooth must work and they don't. They said it will be back in 7-10 working days. Hope they can keep that promise. --------

Have the same problem with my Jabra Freeway, really annoying to get thos silent gaps when listening to podcasts and music in the car. Tried to run navigation on my way to work today to see if that made any difference but it didn't :-(

Thanks for info.
Seems the problem is more related to Bluetooth version & buffering.
I'm planning to buy Sony wireless headset pro with bt v3.
I'll update once I get it hopefully by end of June...

I just tried using my Moto S10-HD after reading this, and thought I would tell you my experience. I have alot of music on my phone, and I just hooked up my BT with Wifi on and no issues, so I started to play music and so far 3 songs and no gaps stutter or anything like that. One thing that does happen which prior phones didnt happen is that when the screen goes to stand by after not touching it, there is a .5 second interruption in the song, but thats it I am currently on my forth song and the phone is in "standby" mode and it plays perfectly.
I have the WWE version of the phone using 1.29.401.11 ROM BL unlocked, rooted, and custom stock rom.

Not sure that it helps you but to share my experience; I have occasional stuttering on bluetooth using my Sennheisers if the phone is in my pocket. I found that I can replicate the stuttering if I completely cover the top of the phone with a hand on either side and cupped together at the top - in fact I can cut off bluetooth playback altogether.
This isn't a normal way of holding the phone obviously - but it does count if the phone is in your pocket, there is already some 'resistance/interference' from the surroundings. Other than that, I have great wifi reception, best of any phone I have had.
Could this be a hardware fault? Maybe they just need to boost the bluetooth signal / improve buffering?
I only got my HOX this week, aside from this issue it is great, no other issues - touch wood

Mine seemed to studder when it was in my pocket while I walked my dog. I sent it in for other issues and we'll see if the new one has similar issues.

Same problem here ! Kinda disapointed !

Same problem SonyEricsson HBH-IS800
I also have a lot of stuttering. It appears to be a very weak signal because it works better (though still not flawless) when I have the phone close to the headset.
Putting the phone in my pocket is already far enough for playback to completely stop working.

I love this phone but this is doing my head in!!

Anyone else having bluetooth issues?
Got my one x after returning a galaxy note after upgrading. All is good on the phone apart from when i listen to music via bluetooth to my external speaker it stutters and crackles all the time. Tried various fixes- different music app,turning beats off,different album,different music format. My old desire played through the speaker with no issues. Even tried turning wifi off to see if that fixed it and its even worse. Someone please help before i go mad.
Regards

The same thing happens with my hox too. I was driving a car today with Bluetooth connectivity on radio and listened some music, and sound started to crackle and break after half a minute. Tried changing tracks, pausing, soft reset and killing all apps, but the same thing all over again.
That's so frustrating, seems like every day I find another bug on my hox. Can't wait to see what's coming next...

There are already topics on this issue through wired headphones and bluetooth headphones and others have said that the issue is seen on other models as well

Is it just a htc one range issue then? When i had the note for a week there were no issues and in the two years i had my desire i had no issues too.

It all plays fine through my Nokia BH-214 Bluetooth adaptor so could it just be compatibility issues with certain stuff?
Sent from my HTC One X using Tapatalk 2

you should change the topic to say that it's about bluetooth problems, and also search to make sure it's the only one. that would be great.

if you're on a locked phone (network lock) and still on 1.26 (anything thats not 1.28 or higher) that might be the problem, there were some issues with some beats profiles so they removed all but 3 now.
apart from that not sure.

[Q] HOX no speaker sound + too fast video reproduction on media playback -

Hi,
I use a black HTC One X since April 2012. The current software version is 4.18.401.2, Android 4.2.2 with Sense 5.0.
It's both beautiful and powerful and the best phone I've ever had.
The only problem I am experiencing lately occurs upon media playback: There is no sound on the external speaker. As soon as I connect a headphone (and switch to wired headset w/o mic using SoundAbout - my headphone jack gave up some months ago) to the phone or a bluetooth speaker, the problem doesn't occur any more. Funny aspect: Playing Videos or MP3s (independent of the used player software) the video reproduction is much too fast and skips. Also, the track position indicators/time counters in music players forward much too fast.
Things I've tried:
reboot (w/o fastboot)
shut down and power on again
reset firmware (this worked initially, problem came back some days later)
I cannot send in my phone because I had to destroy the warranty sticker during a battery replacement I performed some time ago (HTC One X+ Battery). There is no correlation between this and the audio problem.
Any ideas?
Thanks,
Christoph

Hi have you been able to fix this issue? I'm currently having the same problem. I'm running cyanogen mod 10.2
Please help!!!

Any clue?, have the same issue in my HOX+

Bluetooth problem when streaming in car?

None of you guys have any issues with streaming audio music/pandora/google music on your phone to the car? My problem is getting worst and I cant stand it any longer. The music would skip constantly every few seconds making it unbearable. I checked google and few people has problems with it on androidcentral, im surprised no thread for it on here?

No issues here since device came out. Have a uconnect setup in my car and stream everything from my phones BT to the vehicle's BT. My old device did that often, had an older version of BT though I think? I've yet to have issues, sure maybe 1-2 times every week a song might skip a beat but not at all on the regular. If it's a regular occuranxe it could be a bad connection. I would then delete the profile and link from scratch the vehicle and phone's BT.
Also while listening and if it gets bad. Stop the BT connection, then reconnect. Sometimes a reconnection is better than your previous and skips go away. I just turn BT off on my device, wait a few minutes, then turn it back on and let the 2 connect. Try this and the above, those 2 methods should work if not one or the other.

I get static issues if someone calls me while I am listening to bluetooth audio, and then switch back to music. Usually switching to the radio and then back to bluetooth audio resolves this. Try making sure your settings in pairing options are set to allow data transfer between the device and your car. I initially could not even connect my device until I checked off that option.

I used to have the issue with HTC One M7 and Galaxy S4 in my Renault Medianav, but no such issues with the One M8,.

I can semi- validate this issue. I have three Bluetooth devices. My headset for phone calls will get some static if my M8 is also connected to my HTC Stereoclip, but goes away as soon as I'm out of range of the Stereoclip. Because of this, and the fact my Stereoclip runs on battery and often fails to disconnect after I leave car mode, I tried switching out my Stereoclip for the RocketFish Bluetooth Music Receiver.
Now, I don't get the static, but when streaming music through the RocketFish, it skips every 20-40 seconds. I've swapped out the RocketFish twice and have had the same issue each time.
Based on queries on the Android Revolution HD thread, the developers are saying it's a base issue and needs to be fixed by HTC.
I just find it odd that the Stereoclip will steam media without skipping, but third party hardware like the RocketFish does skip. Also, my headset doesn't get the aforementioned static issues with the RocketFish.
Also worth noting I have not had both the Stereoclip and RocketFish paired to my phone at the same time.

Just wanted to second this. Mine isn't that bad, but every so often (3-5 minutes) the music skips about 0.5 seconds. Have tried stopping my navigation app, putting the phone to sleep, and unplugging the charger. Nothing works so far.
Pretty sure it is not a pairing issue since this started the first time I paired my phone to the car stereo.
Needless to say, not happening when listening with headphones or speakers.
Any insight or updates would be very helpful. Thanks.

I have the same problem using a Sony Bluetooth Speaker BTX300.
It's really annoying. It happens with Deezer, Spotify or internal mp3. It does not happen on voice calls.
Maybe it's something related to the Bluetooth bitrate not handled correctly by device ?

Only happens to me in stock radio over bluetooth with the mylink system in the new chevys. No problem with my Kenwood head unit in my Cherokee though

On stock Bell ROM, pre camera/EPSM update, happened every minute in my 2011 Subaru WRX as well as my Motorola Buds. I flashed InsertCoin 2.4.0 and ElementX 0.10 today... no more skipping. Not sure which it was.

I'd had this issue before on my m7 with Pandora. Are you guys using adaway? If so, disable it and try again, it should go away

Hi guys,
Resurrecting this thread. I am having skipping/stuttering issues with my phone when streaming using Spotify over bluetooth A2DP.
I've tested this on 3 different bluetooth devices (Volvo, Belkin and another bluetooth speaker).
The problem is very annoying, once the screen goes off, music would slightly pause every 20-30 seconds.
This happens when using Spotify and TuneIn Radio.. so I'm pretty sure it's not an application problem.
Anyone else having the same problem? I'm running 4.4.3 - 2.07.980.2..
Also, I'm pretty sure this only started happening after the latest update from HTC.

[UPDATE] I've tried doing some tests with turning wifi - OFF and I did not experience any sound/music skips during this morning commute. I will see how this goes in the next few days.

I'm using an app that starts playing music as soon as I connect to my cars Bluetooth. Luckily this app also provides "wifi off on connect"
Gonna give this a try. Really hope this fixes the audio drops. Hate it.

So from one day with Wifi off I can definitely tell it doesn't drop audio on Bluetooth streaming anymore.
So turn your Wifi off to fix the m8 ?

Glad it works for you as well, this has fixed the problem for me most of the time. I use the Trigger app to turn off wifi when bluetooth connects.
On another issue which I don't think is related to the above, on my Volvo at random times, I still have severe stuttering issues to the point that you almost can't tell what music is playing. I've been having this since day 1 with the M8 and not from recent fw upgrade as above. I'm not sure whether this is Spotify or the bluetooth stack tho.
Nevertheless, any of the blueooth issues were something I never experienced with Samsung Galaxy S3, Xperia Z or any other phones. HTC!!, are you listening!?!

rBlink
I have the same problems connecting to my Arcam rBlink at home with my M8. Music dropouts every 20-30 secs. Streaming from my sons M7 is flawlessly.
Stopping Wifi makes it slightly better but is no option since I want to use spotify over wifi.
Could it be a problem with a low bit rate for bluetooth audio?
Arcam gives the advice to increase it for OS X as high as 58.

I am also getting this issue as of late....
I'm using an unrooted Sprint M8 HK phone.
My problem is audio drop out (0.5 sec) constantly. Doesn't make a difference over BlueTooth or the speakers.
It appears that it is related to the phone accessing something during playback which causes the dropout.
It does it when streaming over wif or data... it even does it with audio that I have downloaded to my SD card...
I have uninstalled everything back to when I thought the issues started with no luck.
Anyone with any ideas? I see where some have had this issue and even a hard reset (wipe) didn't solve it.
This doesn't occur on my Verizon M8 which has almost the identical app's installed.

I have an international version M8, bluetooth skips randomly when streaming on car bluetooth and to my sony srs X9 speaker. It seems to happen only with continuos feeds. Mi cousin told me the problem could be that bt device is searching at all times for other devices but since there is no option to stop search i can't be sure.
