Bluetooth audio dropout

[crweidert]

I just got a Z3 compact.  I switched from a Moto X that did not have any bluetooth issues (which is still in my possession in case I can't fix this).

Anyway, when I connect to my Pioneer MVH-X560BT stereo, music will play but the audio will drop out completely every few minutes. The audio will go out for around a second. It's not lag because the song doesn't also pause when the bluetooth audio drops. After a second audio will return. I have tried many apps (Walkman, Power amp, google play, spotify, etc.) and they all produce the same occasional pause.  I have used a few different phones with this stereo and have never experienced this issue.

I bought my Z3c online from someone who had unlocked the bootloader and installed a custom ROM. I found out how to install the stock Sony rom with Emma and thought that would fix my bluetooth issues. It did not. I doubt an unlocked bootloader would affect bluetooth.

I have just tried my Z3 with a different bluetooth speaker and it works without skipping.

Both my old phone (Samsung) and the Pioneer stereo are bluetooth 3.0; they worked flawlessly together.

Therrefore it now seems to me that the z3 must have a backwards compatibility issue with bluetooth 3.0

Edit: I was unable to overcome the compatibility problem with Sony Z3 compact plus pioneer stereo. I therefore sold the stereo and replaced it with a Kenwood BT53U, which works flawlessly.

Same issue here with a brand new Z5 compact and the Pioneer DEH-X5600BT. Old HTC one m7 worked Great but this?.. It Will be with tears in my eyes I need to go back and run aux cable because Sony cant fix this.. The Bluetooth mic I had to mount down half the car to install looks dumb now..

Same problem with Z5, on same Pioneer car stereo, even now with 6.0 marshalmallow...

Greetings from Ukraine!

Same issue here. 

Xperia Z5 Compact (running Android 6.0) plus Pioneer MVH-x560BT. Sometimes it takes mercy upon me, allowing me to listen for a song or two without dropouts. But mostly there's a second of silence every two minutes or so, which keeps driving me crazy.

Switching off Wi-Fi doesn't help. 

Both Lumia 525 (which is probably the cheapest smartphone out there) and Nexus 7 Tablet perform flawlessly.

Not quite sure now, what was all the fuss about Sony's superior software and audio quality :(.

n5100bt user now, with the z3 compact. the bluetooth problem is solved. but not everything is perfect. 3 times in one month, the sony mex n5100bt froze . i had to reset the thing, loosing all my presets. the cause was a flac tune on my highspeed usb dongle. so, sony mex n5100bt might be a flac player, but not a perfect one. a good one, but not perfect. would i buy again the z3 c? yes i would. would i buy the n5100bt? yes i would, unfortunately, yes. so , if you have questions about the 5100bt, ill answer them.

Hello,

I have the same problem with my XPeria z3 compact since I upgraded to Android 6.

It randomly disconnects from whatever audio bluetooh receiver it is connected to (reproduced on Volkswagen car audio, Sony DR-BTN200 headphones, avantree saturn apt-x receiver, UE Boom 2 speakers). I have tried to debug the issue, and here is what I found.

I have collected the logcats during the disconnection and I discovered that just before each time the bluetooth disconnects there are two lines concerning "BeaconParser" I think this has to do bluetooth LE. Here is an extract from the logcat:

each we see lines like this just prior to the disconnection:

I hope this will help Sony fix the issue.

I am no longer a Sony user. I find unaceptable the lack of respect from Sony, who in 3 years didn't had the time to fix this problem. Z1, z3 compact, z3, three Sony phones with this problem is more than enough for me. A cheaper phone does the job better then those above. Huawei p9 lite user now.

hi

same problem here, still no solution !

[bladE_1]

I have experienced exact same audio drop out problems with Sony Xperia L1 and Pioneer MVH-X560BT. However my Pioneer works flawlessly with Samsung Galaxy and even with Lumia 640 XL.

I have similar compatibility problems with other Sony products as well and I have gave up until now. It's better to avoid Sony if just possible, since they do not give about sh*t about customer experience. This audio drop out problem will propably get never fixed. I have HDMI audio problems with all SONY TV's and one of the models with problematic behavior is very ancient (KDL-40W3000). All the displays works theoretically, but i get invasive OSD messages regularly when audio stops and starts again like in the link below.

Very annoying like this bluetooth sreaming issue with Xperia L1.

I have the same problem with my XZ when connectwed to my car's phone hook up.
