A2DP Issue?

I've had a nice BT headset a Sony BT10CX which has always played music well. This week it only produced sound in the left ear. Fearing the worst I reset my VIII and the issue was still there. I sent the phones back thinking they were faulty and got a Jabra BT320s instead but the same problem is reproduced. After a bit of searching I've just installed the HTC Bluetooth hotfix which...hasn't changed a thing.
I've tried the Jabra with my v1615 and it works as it should. Any ideas?

Have you added any new apps or installed any tweaks just before it went wrong? Otherwise, backup your data and do a hard reset.

That's wht I feared. Pending any other suggestions I think that's the way to go.

Okay, on a plain T Mobile ROM the Jabra connects but now "Set as Wireless Stereo" doesn't even show up as an option, just "Set as Hands Free". I had both options before (even when sound was just coming from the left ear). Do you think this is a Hardware issue and therefore a repair/replacement needed?

Just one more thought, have you used 'Kaiser Tweaks'?
If you have, just de-select or disable 'Use Joint Stereo' in BT as this is designed to pass both Left and Right audio to a mono unit (for music over a single BT earpiece) but it has also been noticed to cause problems with certain stereo headsets.

Sorry, I wasn't clear. I have hard reset to a plain untweaked T Mob ROM and now have this issue.

I'm using BT-10CX with alex's tilt MM, sound comes from both ear, stereo; but i have another problem It can't connect to the tilt automatically when turn on after it is turn off!
Can your BT-10 connect to phone automatically once it turn on OR you have to go Start>Settings>Connections>Bluetooth and then set it as "Set as Wireless Stereo"? Tried all the ROMs (alex, Dutty v4, at&t Genuine, etc) and Schap's advance tools but the issue still there.
Any trouble shoot ideals? Great thanks.

I've always had to manually set it each time I've used it.

Bluetooth Issue

So I paired the One with my QED uPlay at home and I'm having issues. The phone has to literally be 30cm away from the receiver or the audio will start getting distorted until it eventually cuts off. I have two uPlays, issue exists on both so its not tbe receiver. Also my iPhone 4s has no issues either. I was hoping the One had better audio than the iPhone since it has aptx, but its quite the opposite. Has anyone tried bluetooth music streaming? Is it just a faulty phone?

Bluetooth and Wi-Fi both use the 2.4GHz channel. Asus had issues with the Prime because of its all-aluminum design where they had to greatly amplify the Wi-Fi signal and use diversity antennas to get through it. HTC uses the latter on the One. When used together, the Wi-Fi signal can overpower and interfere with the BT signal. Try turning off Wi-Fi and see if your connection quality changes. You're the first one to mention a BT issue so it could be unique to your device. Time will tell.

I have had a problem with bt connecting to my car (audi a1) I can hear the call but the other end cannot hear me. Going to delete connection and try again tomorrow.

Thanks for the replies. I switched off WIFI, re-paired the device and bluetooth started working perfectly, so it makes sense it was interference. Strange thing is I turned WIFI back on and bluetooth was still working fine. I'll do further tests in my car tomorrow see how it goes. If I'm not convinced I'll just get the phone replaced.

I have also had issues with bluetooth paired to my hands free car kit. Issues have surfaced when streaming music and also when making audio calls via bluetooth.

The One X had a similar issue:
http://forum.xda-developers.com/showthread.php?t=1688538
It could be that when I was first trying the WIFI antenna was stuck on high power, which caused the interference, but when I reset the WIFI it reduced its power and no longer interfered with the BT. I have changed the WIFI at home to run at 5 GHZ, but work still runs on 2.4.

I am running 1.28.401.7. How did you update to the latest ROM? I don't want to unlock my bootloader in case I need to return it.
Did you used to have the same exact issue in the previous ROM?

Apparently 1.29.709.4 has been officially released in Taiwan by HTC, so it shouldn't be long before the update arrives to the rest of us (hopefully).

got the same issue...some times I got no lags in audio streaming, but sometimes they are there...until it (maybe) will be fixed I'm using a widget, my cousin has coded for me yesterday . Quite simple solution. If I press the button, wifi turns off and bt turns on...works fine for me, so far

[Q] Anyone have issues with Bluetooth A2DP?

I got my Note 4 yesterday and was trying to connect my car radio (Jvc Kw-V50BT). The phone connected, but when trying to connect the media part of the phone it just doesn't want to connect. I had a LG G2 prior to this phone and it worked fine. I checked JVC and it should work with Bluetooth 2.0 and up. This is baffling my mind right now. I might have to factory reset my phone and try it that way. Any help would be appreciated.

No problems here I use my Ford touch and everything is fine

If it still doesn't work...try another BT source.

Works better with my Ford Touch than any phone previously.

Try reseting your radio... not sure how you do that with your model. Make sure you delete the old pairing.

bt 4.0, which most newer phones have, is very touchy about what it works properly with; I have a bad time trying to stay connected to my vivosmart garmin band, but pairing to my car and plantronics headset works 100% of the time.
my wife has a G3, and has the same issues; some things work 100% of the time, and some others only work occasionally

A2DP Issues
I just got my Note 4 yesterday, and am definitely experiencing some (admittedly minor) issues with A2DP in my Honda CR-V EXL 2012.
When playing music over Bluetooth, I experience the infamous "Galaxy S5 intermittent half-second skip". Also, I have noticed that when playing an album or playlist, if the screen on the phone is off the currently playing song information will not update.
For example:
I am listening to "Gimme More" by Britney Spears on the album Blackout.
"Gimme More" ends, and the next track "Piece of Me" comes on.
The car screen will continue to show "Gimme More' unless I use the forward or back buttons from my steering wheel or dashboard to manually change songs.
This causes the screen to update to "Piece of Me"... albeit with a brief delay.
Very odd...

I finally got it too work, but I had to get an app to help me out. I think it was called Bluetooth Manager or something. I forced it to accept the media and got it working. I was getting frustrated when even a factor reset didn't help.

Yes, I have the stuttering too on my Note 4. What can I do about it?

Note 4 note; note, Bluetooth.

This may not help but.. Got my Note 4 four days ago; had the Note 3. 3 Had 0 problems with Bluetooth; 30 ft. through walls, drops rare, auto connected to my car while I was in the house. Note 4 range 15 feet,, constant drops and fails to connect. Hoping to get another 3 or 4 from T-mobile but that has not happened yet. I'm good carrying both. The 4 makes calls (although the speaker is a downgrade. The 3 connects to all my stuff. just like the old days at work. :fingers-crossed:

This is what I'm using. No issues.

It's not super new. Just a decent deck. But, the rule is the newer the better with flagship phones:

Not sure if this is related or not - I have an open thread about blue tooth streaming issues with my car...
What I have found so far -
My car (2012 Subaru STi) has two methods to pair a blue tooth device... entering the setup through the steering wheel is the only way to save a device for auto connect and play, entering the setup through the head unit lets you save and select a phone to pair, but you must select pair each time you get into the car. If you do option #2, I have the call audio and media boxes always unchecked. - see if your car has a different method for primary user/secondary user blue tooth set up
and secondly, my main issue was that while listening to spotify my radio head unit would say BT-Audio Paused out of nowhere, when in fact, the spotify track still shows playing and the song is progressing.
after lots of troubleshooting I think this may be an issue to spotify itself and not my phone (I am now testing Pandora/other streaming media to see if they do the same interment freeze/odd stuff)

I've also been having problems with Bluetooth devices connected to my Note 4. Previously, I had been using an iPhone 6 and I didn't have any issues with these devices. Now, I'm experiencing connection problems with my Jawbone UP24, my Plantronics headset, or my Jaybird stereo earbuds, and other devices. Once I reboot my Note 4, the BT connection is usually back. But, sometimes I have problems even after I've rebooted the Note 4. If I power cycle my BT peripheral, I'm usually OK as well.
So - my question is: could it be possible that some of my Bluetooth peripherals (like my Jawbone UP24) may be causing some type of interference? Or, do I have faulty hardware?

Older Bluetooth Devices always seem to be hit or miss on the newer Samsung devices that have been coming out. May be its age being the factor, lol. :silly:

Bluetooth calling audio not working (Bluetooth media audio is)

When I first got the new HU it worked fine (actually surprising clear given comments about mics here), but now bluetooth calling doesn't seem to go through the speakers although people on the other end of the line do hear me? Bluetooth streaming of music is fine though which confuses me. Also the sound isn't coming out of the phone itself and the Bluetooth options on the phone have send media and phone checked. So it is like the audio receiving of the call isn't reaching the speakers.
So I am guessing that it seems like something on the software or settings side has got a bit wrong rather than hardware (all I've done there is cut some rear speaker wires to add a hi lo convertor and add power to antenna). Main things I've done on software side since getting this are install add the Xposed Framework, Carservice (uninstalled) , Package Explorer, MTC Keys (disabled) , Xposed MTC (now uninstalled), but I have uninstalled most of this so don't understand how this could be impacting it..
Anyone had anything similar and might know what has caused the bluetooth phone to stop working?

Mine has suddenly decided to stop connecting to Bluetooth at all 90% of the time.
The Bluetooth in these radios is total and utter garbage... that's all I can say.

Went in the car today and everything worked fine!! Very confusing. I'm wondering if it was carservice or one of the other apps after all?

Not sure if it counts but there is a software fix for bluetooth in the Bluetooth mod .. Under hardware mods..
There might be a connection between the Bluetooth stack and other software coming in..
All I know is that this slight change of drivers for us has saved us from doing hardware mods and for now its working perfectly for a number of us..
Check it out if you get problems as a slight chance via settings may fix some of these problems for you.. Worth a try

Cheers- I'll keep this in mind if it happens again - it definitely seemed like a software issue.

My XZ2 often dropps known Bluetooth devices

Hi all,
I have the issue, that I need to reconnect my XZ2 to my BMW 1series (F20) really often, because it does not autoconnect when the ignition is turned on.
So I need to pair the XZ2 again and again with my car.
Also my BT-Sony Headset is affected.
It seems, that my Phone drops sporadically all paired bluetooth devices.
I noticed that I can bypass this problem with a daily reboot of my Phone. But this shouldnt be the Solution.
Any Ideas? Can someone confirm a Bluetooth problem?
Stock rom. Build 51.1.A.11.51 @ H8266

Try using new flasher to reinstall the latest firmware.
But delete the "userdata" file, it would remove your userdata.
I gather root, backuped my stuff with Titanium backup and wiped userdata, too.
Now my smart lock is working again.

Thx Martin. Hope pie fixed it.

I have an odd Bluetooth issue too, lately it's been disconnecting the ear buds while changing streaming apps (i.e. from Tidal to Spotify or Podcast) or when moving between networks, either between access points or from WiFi to cellular data. Just started happening this week. Didn't change anything that I can remember. It's almost behaving like there is a power saving feature enabled which is trying to save on Bluetooth use. Sometimes it'll reconnect on its own and sometimes I have to toggle BT. It's weird.

I also have Bluetooth issue.
I have a Bluetooth weighing scale,my xz2 can connect to it but everytime I sync my scale data the scale app gives me a Bluetooth error, however, I also have a xz and it works well.
And I also have a Sony ear phone(MDR-EX750BT), yesterday I connected it but it didn't play any sounds I had to reboot my phone ,then the issue disappeared. I don't know when the show again.this shouldn't be a Sony quality

yeah, ditto. The connection to my Sony WF-1000X earbuds is stable now, with no disconnects like I was getting with the later updates of Oreo.
FYI, I had to wipe my user partition to do the eventual update. the first flash via Newflasher where I kept it intact apparently went bad and messed up my radios and fingerprint scanner. that's the first time I've ever had issues doing that.

Now I am getting Bluetooth problems.
The music has stuttering and normal intervals.
Very disturbing.
I contacted the Sony support.

with what Bluetooth device?
so far with Advanced 3 and Sony WF-1000x earbuds it's been stable for me. As well as my car connection (Land Rover) and some shower speaker I've been using it with.

Need to test it again.
