It doesn't. But it might be not fully related to bt as I had to copy the flac test file from ext sdcard as stock music player didn't like my external storage configuration. Strangely so, cause I'm almost sure it used to work before. How would you force start media scanner?
[Xperia Z5 General] gm007:
Not sure about media scanning for music,but for pictures there is in album app a media fix that can scan for all the pictures.

Maybe clear data for music app.
[Xperia Z5 General] millicent:
It's not related to storage location, I think. I just realized gm was storing its sh1t on internal sdcard. Just changed that. So the skipping/stuttering happens mostly in google music. It also happens in poweramp and gmmp but less frequently, less skipping and less artifacts too. The Google music skipping mostly occurs when using the phone for other tasks such as navigating Tapatalk or typing here. I dunno what to think of stock music player. Don't tell me Sony won't look at this if only happens in third party apps.
[Xperia Z5 General] gm007:
Maybe stock music has bigger buffer that's why it's not skipping.

Do power amp or google music has some setting to increase the buffer?
[Xperia Z5 General] millicent:
Not specific to bt. Poweramp has a bt thread priority that haven't tried yet. However, I'm listening Google music wired, same headset as earlier but wired, no issues.
[Xperia Z5 General] bartolo5:
Hey there. Thanks for creating this thread. I'm on the very same boat.

Z5 dual here, E6683. I tried 'customized RU' and 'customized HK' but both present the very same problems. I tried many things and it does seem like a CPU bound problem but it's still quite random. Sometimes I can listen to music for a while without problems, but then it will start skipping like crazy and you have to stop it. Wired headsets work fine. It's true that seems to happen more on Google Music for me too, but it's happening also but less often on Tune-in or Spotify.

It has been incredibly frustrating. I use bt audio a lot so this makes my device unusable. Sort of fed up at this moment with Sony. It's march now, 6 months after release, and my device is still not working as it should on release day. MM did fix lots of issues thought, but it sort of feels Sony is in perpetual beta with their flagship device.
[Xperia Z5 General] danw_oz:
Mine was doing the same, and often, reboot fixed it pretty much for me
[Xperia Z5 General] millicent:
I had the z5 connected to my car bt, listened to google music on my way home, about 30 minutes, no problem whatsoever. But the car bt is not aptx..I am going to look at logcat tomorrow. Anyways, unless more mm z5 owners come forward with this issue it's hard to convince Sony there's a problem at all. And I didn't even see one mention of this on talk.sonymobile forums.
[Xperia Z5 General] millicent:
It didn't here. I mean between reboots I'd get smoother streaming for a while, then it's back again to freezing and noise artifacts. I am trying for a while now to find a pattern in this, maybe another app that interferes, something in our setup that causes it. I am close to factory reset and try again, I will take a look at logcat though I don't hope for too much.

I use dayli bt audio and I don't have any issue.. (true only stock music player) (android 6.0)
[Xperia Z5 General] Loz1:
This has been happening with Android for age's you can find threads on this all over the Internet. But it's hit and miss as to what devices it happens with. I'm my car I don't have any problems with bt skip but in the house from my phone to my Arcam rblink it skips and yes is bothers me too I've tried to isolate what app or what ever it may be in the phone but nothing... and like wise surcingles the Web no one seems to have a fix. Well now I'm on MM I can give up thinking a fix might come in this upgrade.... well it didn't.

It worked perfectly for me in lollipop.
[Xperia Z5 General] hunterfred:
It's the issue with the 4G, 2.4G, 5G signal that we commonly encounter , they interfere with the ldac and the aptx bt transmission. Furthermore, what I found is that the freezing issue is highly related to the cpu using and the internet using. Turn your phone into flight mode and left only bt open and check again.
[Xperia Z5 General] Oneironautics:
I've noticed a skipping/cutting behaviour when listening through bt in my car. No problem whatsoever when on lollipop but now it's terrible. It's actually in a state where I'm forced to use something else as a source.

Obviously, when the only thing that have changed is the OS version it's easy too assume some kind of bug. Worked flawlessly with my z3 and z5 lollipop.

Marshmallow has been a nightmare so far i terms of audio.

I tried the airplane mode in spite of being a bit skeptic about this: after listening for half an hour I can conclude airplane mode (with bt on) helps, I didn't experience any significant freeze with google music (in offline mode)
[Xperia Z5 General] Loz1:
Well again I'm in my car and have been using the Samsung player for over an hour and not as much as one skip..and I'm not in airplane mode. I will go home and connect to my Arcam rblink later and see what I get. While I'm streaming YouTube music etc.

Having occasional small skips in my car, TERRIBLE skipping on my Amazon headphones that support aptx
[Xperia Z5 General] millicent:
I dusted off and charged my old LG hbs700 bt headsets without aptx, I am still listening while writing and stressed the phone any way I could. No problems whatsoever.

To resume, I can only reproduce this sound freezing over aptx. I have 3 aptx headphones all of them are doing it. Pretty sure, at least two was using with lollipop were fine. Now, my car bt (blulogic, stock installed by Toyota), no aptx for sure works fine. I also tested fine my Sony ht ct770 soundbar, I don't think it has aptx. And finally, my old LG bt headphones work fine too.
[Xperia Z5 General] bartolo5:
Is there any way to force the phone not to use aptx to work around this?
[Xperia Z5 General] millicent:
Just guesswork as don't have root but these codecs could be on filesystem. Then simply renaming them might disable aptx. On my HTC One m7, the aptx modules are found in /system/lib/libbt-codec-aptx.so
[Xperia Z5 General] Loz1:
Guys just to let you know since Mt MM upgrade on my S6 edge I've been running bt test with internal music and streaming from YouTube and tune in radio to my car or my home hifi via the Arcam rblink I haven't had one skip in hours of playing music. So is my problem gone... I truly hope so...;)

[Xperia Z5 General] haithamkhc:
Gosh I am so tired giving Sony a break every time they screw up something ever since the Xperia arc and s and z. When I left Sony for the note 3, I had the Note 3 for 2 year never had issues like these and I was quiet happy it was functional. Now before i bought the Z5 I said come on give them a break it's 2016, they must have learned from their mistakes, N O, I was totally wrong. They r still struggling in the software department, I forgot how bad they were in term of software support . I have been waiting for MM to fix many issues in Lolipop including bluetooth stutter and freezes in my car, instead after a long delay, I get stutter and freezes in all my bluetooth speakers even after I factory reset my phone. Now I can't play music with my bluetooth headphones in the gym and in my car speakers. How can they screw up somthing like this
[Xperia Z5 General] millicent:
I am bt freezing/stuttering free for almost 2 days now!

I am testing with same Google Play Music over lte mostly, all tests with aptx headsets. The app is configured to cache its library on external sdcard.

As I paid much more attention to sound quality while testing this issue, I believe there are still microskips or otherwise some sort of noise artifacts, but decided they're not too bothersome as they're really short now. And what's to say the microskips weren't there on LP?

Anyways, what did I do to solve this? I am not sure if I have the actual answer, but the only change I did to my configuration is changing the mobile provider. That's right, 2 days ago I switched to koodo (from Rogers). I am not sure how that makes any sense but that's all I can tell. Will add to this thread in case I figure any other relevant info or if the issue comes back.

Good luck ? to all. And happy belated St Patrick day!
[Xperia Z5 General] haithamkhc:
Are they gonna fix it anytime soon. I use Bluetooth devices everyday on a regular basis. Now my latest Sony 600$ flagship phone is unusable; and no words from Sony yet about coming fix for the Z5. I hate to say this but I am done with Sony and all their bugss, I going back to Samsung now that their phones r water resistant, sd card support and way bigger battery and bug free compared to Sony
[Xperia Z5 General] hunterfred:
Newest update: I flashed the 6.0 ftf again and chose all the wipe option including wipe user data, the bt issue finally resolved with no freezing and lagging at all.
[Xperia Z5 General] El Edwina:
I've flashed several times, wiping the data too, with no luck.

Did you use Flashtool? If so, what options did you select? Which firmware did you use?
[Xperia Z5 General] danw_oz:
Thanks, that saved me some time, because I was close to doing this myself, although I wasn't entirely sure this was the problem because the problem didn't present itself for me right away, I got about a week before I got my first skips during playback on my Sony car stereo

My best guess is an issue with the new Android ART runtime, which is obviously going to behave differently than dalvik. That is if we didn't get jipped, and Sony released delvik instead, well I can't see an option to enable it anymore.

I got a doosey the other day, call came in through car audio, I couldn't answer it, then the phone continued to send ring tone over the car audio even after the person hung up, check phone no call coming in, this was only stopped by rebooting the phone

Turn's out we are not the only ones, even the Google devices are having the exact same problem here is one link http://ausdroid.net/2015/11/17/google-working-fix-nexus-6p-bluetooth-issues/ and there are plenty others with the exact same symptoms, so google issue rather than Sony specifically.
[Xperia Z5 General] sci2:
If it's not one thing, it's another. I had all sorts of BT disconnect issues on L. The phone would randomly disconnect from my car, and my Pebble watch would disconnect half a dozen times per hour or more. I was elated to find that on MM, those issues are gone, but now any kind of audio streaming introduces these skips. If I put the phone down and simply leave it alone, it is mostly fine (MOSTLY). But this wasn't a problem on L. I could still use the phone while listening to a podcast for instance. Frustrating.
[Xperia Z5 General] cheremo:
Is there a solution for the 6.0 bluetooth issues? I can't hear music in my BMW without stuttering using Spotify. :mad:

I updated the stock Lolipop to stock MM with the Sony PC companion.

Is there any Z5 statement from sony besides the z3 changelog? Should i factory reset my Phone?
[Xperia Z5 General] Loz1:
I would probably say although most mat not want to try but wipe and start from scratch. As I said previously I was getting the skipping on bt Wether I was streaming from YouTube Tunein radio or even from my storage on L. More so in the house via the Arcam rblink but not so much in the car. Now I've gone over to MM... it's compleatly gone. I don't want to speak too soon but it's been a few days now and I stream every day and I've not had a fault. And mine is stock.. no tinkering around the edges... and I'm loaded with apps etc... so it must be the OS at fault. Good luck all I'll keep watching this thread to see how things pan out for you.

Thanks for your answer.

I have contacted the Sony support.

i've flashed my z5 (E6603) like a week ago, the first 3 days i have no issues with BT (i was so happy thinking issue was fixed) after that the bt problems came back :(

to make it work around in my '14 chevy malibu is to turn off and on the BT, and after it connects to my car wait for 2 mins before to choose BT as source seems like

the phone is sending too much info to my car, after that it just work fine, no audio cuts or disconnections.

[Xperia Z5 General] bartolo5:
Not necessarily the same issue. I have a 6P and a Z5. I did experience these BT audio dropouts but they would happen very every now and then. On my Z5 is just all the time I'm using the phone while using bluetooth audio.
[Xperia Z5 General] millicent:
But isn't this issue isolated to aptx? At least, in my case, my 3, non necessary older but non aptx bt devices play without the constant stuttering, popping whatever.
[Xperia Z5 General] TheTecXpert:
IF aptx is the actual cause on your phone. Disable both APTX services/apps in your phone temporarily.. Give that a try and let me know if the issues go away :)
[Xperia Z5 General] BCN_Surfer:
Hi!

I've been having this issue too since updated to MM, mainly listening to Spotify and GMaps. However, I realized that if I restart the phone it solves and I can listen for hours through BT without any stutter or problems. So now I just restart the phone before getting into my car and everything is fine.

Check if this works for you too. If so, it's a pretty simple workaround until sony fixes it! ;)
[Xperia Z5 General] mrbubba999:
How do you disable it? I'm not rooted and can't be rooted
[Xperia Z5 General] millicent:
Are you kidding me? Not sure you're mocking him or really considering this.

For what's worth, IF you had root, you can mess with the aptx modules in sys folder, their location vary with os, and give it a try. Easier to use devices without aptx though.
[Xperia Z5 General] mrbubba999:
Nope not mocking, if aptx is disabled and Bluetooth works fine, then we know what the problem is. I don't have any Bluetooth devices that don't use aptx, so this way would have been easier, however I'm not rooted and can't do my device
[Xperia Z5 General] millicent:
I feel the problem might be wider and more difficult to reproduce, consequently more difficult to fix as well.

Since I started paying attention to bt sound, it seems to me its quality decreased overall, I mean even over regular codecs there are undesired artifacts, noises etc, it's only that aptx is exacerbated to almost unusable.

However, as others noticed, sometimes and for short periods sound would be fine. In my experience, after rebooting or safe mode, or changing the sim card or during airplane mode + bt, sound can be OK. The problem is it doesn't last long enough to consider a viable workaround.

I've already factory reset mm, I wouldn't go back to LP just yet, others rolled back and said it was fine, for now am using my m7 for music stuff which still works fine for aptx or sbc and waiting for a Sony fix.
[Xperia Z5 General] Chilling_Silence:
Posting this here (Re-sharing what I posted over in the Sony thread): http://talk.sonymobile.com/t5/Xperi...-stutter-after-marshmallow-update/m-p/1113126

Confirming again that the issue is *not* fixed in 21.1.A.1.185 on the Z5 either

Tested using:

Streaming through Google Play Music

Local playbck through Google Play Music

Local playback through WinAmp

Local playback though "Music" app

Turning off WiFi while playing

All streaming was tested 3x to each of the following:

Sony MEX-N4150BT car stereo

UE Boom

Jabra Halo Fusion

Local playback was tested from both a file on the internal storage, as well as the SD Card

Streaming playback was tested both via 3G and via WiFi

All combinations suffered the same issue.

Flashing back to Lollipop and doing a factory wipe resolves the issue. Flashing back to Marshmallow and the issue returns.

Have streamed for ~100 combined hours on my girlfriends CM13 Galaxy S5 (Flashed back in December '15) to the same Sony MEX-N4150BT stereo and the UE Boom with *zero* issues, so I'm not willing to blanket write this off and say it's a Marshmallow-specific fault, but rather a Sony-specific Marshmallow bluetooth issue.
[Xperia Z5 General] Chilling_Silence:
What I have found though is that it seems to be CPU / Memory related. Eventually after a while it gets more and more frequent, and doing things like loading a basic web-page will make it skip. I'm unsure if this is priority-related where the bluetooth streaming doesn't seem to get priority over other tasks, or if it's memory related and it's skipping as it tries to free up memory for something else.

A quick workaround is for me to hit the multitasking button and kill off all apps, but after a little bit of use it happens again. Just the usual things like Hangouts, G+, Facebook, Google Photos, the Camera app, Chrome... Not ideal, but that works short-term for an hour or two of general use.
[Xperia Z5 General] millicent:
Rebooting or rebooting to safe mode and back sometimes give me even days of non bt issues.

Otherwise, I updated to .185 two days ago, no issue on aptx yet, I was hoping it'll be fixed but you ppl shattered my dreams..:)
[Xperia Z5 General] mrbubba999:
Argh forgot about this bug... Until yesterday when at the gym trying to listen to music during my workout!!
[Xperia Z5 General] Chilling_Silence:
For what it's worth I'm not convinced this issue is caused by AptX, as my UE Boom skips and it doesn't support AptX. Same for the Jabra Halo Fusion. Both only support A2DP.
[Xperia Z5 General] millicent:
It happened for the first time today on 185. Mostly when I do other activities besides listening. I almost always listen via aptx only. I have tried once non aptx headsets and seemed to work better hence I assumed it's aptx only issue however there are other users on that Sony forum complaining about both.
[Xperia Z5 General] Chilling_Silence:
Yeah, unfortunately those "other activities" can be anything like it doing a background sync and getting a notification / email / changing cell tower / whatever.

Definitely not just limited to AptX unfortunately.

Another theory is it's happening when you have multiple devices paired. I currently have my Xiaomi Mi Fitband paired as well, so I'm tempted to leave it at home tomorrow, take the phone to work, and see if it still cuts out or not.
[Xperia Z5 General] Xaviez:
Definitively nothing to do with several devices, I only use a single SBH-20 and have this issue. Getting really tedious to the point of me considering other phones instead now.
[Xperia Z5 General] Chilling_Silence:
I've already got a Xiaomi Mi5 Pro (I wanted the shiny ceramic body model with 128G RAM) myself on order.

I'm trying running my Z5 in Safe Mode (Push and hold Power button, then push and hold the Power Off line, then confirm with OK) for a while to confirm I'm still getting the issue in Safe Mode, just-in-case.
[Xperia Z5 General] Chilling_Silence:
Yeah it still happens even in Safe Mode, so it's definitely not something that I've installed either.
