[Q] Lollipop: Problem playing HE-AAC audio through Bluetooth - Xperia Z1 Compact Q&A, Help & Troubleshooting

Hello folks,
it's been quite a long time that I've been here. That may be because I was quite happy with my phone during the last year.
However, with Sony's Lollipop update for my Z1c, I ran into a really annoying problem.
Nearly my complete collection of audio CDs has been ripped to HE-AAC files. It was never a problem to play them on my mobile phone, not with my Z1c and not with my prior phone Acro S. For quite a long time, I'm using Bluetooth to transmit the audio to my car's audio system, to some headphones and to a small battery-driven desktop speaker.
Since the Lollipop update, all HE-AAC audio played via Bluetooth becomes distorted and is very ugly to hear. It works fine when played through the phone's own speaker. All other files (I have) are played fine also via Bluetooth - including regular AAC, mp3 and so on. The problem appears with the Walkman app as well as with Google Music. It is not present when playing with VLC (which apparently has its own decoder).
I have attached a sample file to this post so that you can hear what I mean. I've also attached one AAC file resulting in this distortion. (Please respect the copyright of this song and just use it for this research only and delete it afterwards!)
Sony's support says that I should reflash (aka repair) my phone's OS. However, I guess that the problem is not limited to my phone. Has anybody of you heart of such a problem or maybe experienced it yourself? Could anyone be so kind to check if it happens with your phone, too (Sony OS and maybe Cyanogen or likewise, too)?
Regards, Mattes

I have the same audio issue as everyone else. I have the Sony Xperia Z1 - It seems that when I have the equalizer and sound effects activated the sound gets distorted after a while. So, the only solution for now is to disable equalizer and sound effect off. It all started after the lollipop update. It has nothing to do with earphones or headphones as I have tried multiple from Bose, Sony, Creative Labs and others and the sound is distorted on all of them.

Edit: It's working well with dolby patch

That actually seems very similar to the issue I kept having with my Z1 Compact and when in a call via bluetooth connected to my car... it would get super distorted every few minutes and made the call impossible to hear. Music did play fine, but would skip every so often. Going to try disabling all that audio stuff and hope it works!

music playback issues

I love the phone (got it launch day) puts my Mytouch 3G to shame. I love everything about this phone....... well except for one thing.
I am having a hell of a time with audio playback. 60% of the time i try to play back music on stock music player it tells me that the audio format is not supported on this device. using Winamp wasnt much of a help as it will just cycle through songs and freeze up.
resetting the phone helps sometimes but not everytime.
I also tried removing all the music from my phone and re-copying all the files. still an issue.
I've also noticed it acts up a lot more via bluetooth (i have a pair of rocketdog behind the ear headphones)
I'm stumped...
Any ideas? Anyone else getting this issue?
codec, song encoding comes to mind
also try with different amount of songs
i know on the old SGS if you had more than few hundreds of mp3 or mix format songs in it, it can drive it crazy
so try a couple hundreds, then work your way up, until you find the amount of files it can read before it becomes too much.
all this can be fixed once rooted, and installing better media players
winamp for android sucks by the way
you should try the ICE cream leaked media player from stock android, it's better
Curious why not just stream the music from ur pc?? google music is practically flawless
Seen a user in another thread had to format their card in this phone, then add music. Try that.

I tried this last night. didn't help much. I'm 99.98% sure it has something to do with my bluetooth headphones. Going to buy a new pair and see if it makes a difference...

If you get the sony ericsson mw600, you'll be amazed at their features. I love them and use them all the time and the battery lasts longer than the specs say. I can get 14hrs out of them.
Just picked up a new set of headphones.... does the exact same thing.... odd.... wondering if its just my phone or if this is a glitch...haven't seen anyone else report this.
Pandora and google music work great with my motorola s10-hd headset...

I'll be getting my phone tues. I use sony dr-bt22 bluetooth headphones.... will report back.
I have this problem when steaming music over A2DP through stock Music app or Google Music. All 320kbps fixed rate MP3s. I've tried via my integrated car audio, computer, headphones... all same result when playing local media. Streaming via Rdio works completely fine. Playing local media without A2DP also works fine... Logcat reports some kind of permission related problem...
Weird, I play FLAC or 320s all day long on this thing and no "Format Unsupported" has come up on regular headset/aux cable or BT. I have however, had a problem with the music stopping when I get a notification..the time continues to move but no sound.
Just an update, my stereo BT headphones work fine

[Q] Bad music sound quality on Desire via headset

Hi all,
I really enjoy listening to music a lot, and wanted to use my Desire as a MP3 player, so I don't have to drag my iPod around as well.
Now - I get _really_ disappointed with the quality of sound that comes out of that phone.
Be it net radio, last.fm or flac music on the SD card, I hear a lot of interference from the WLAN and 2g/3g network on the headphones (you know. bssssss / dak-a-dak-a-dak, brrrrr, depending on which connection I am on). Not very loud, but very disturbing if you are listening to low-volume music.
Do you suffer from the same problem? Did anyone find a solution to this?
(I found a few similar posts, but none really matching as they cover speaker/BT headsets)
I use my Desire to play mp3 and to listen FM and streaming radio and I've never heart any interference.
Maybe it's another device what is causing the noise?
I also use my phone to listen to music / podcast and never noticed any interferences.
Did you check your headset cable (I've noticed it's the biggest unwanted noise generator when listening to music on the go) ?
Well - partly it is indeed my headset cable.
Although I am using Sennheiser cx150, which sound quality is really good in my opinion, it seems that the cable is very poorly shielded.
So I tried with various other earphones, and the interference is less. Still not gone, which still annoys me, but less.
Oh well, i gonna spend another bunch of money for new headphones until I get a new phone :-(
Thanks, all.

[Q] Bluetooth Streaming Audio Issues?

I'm having issues with distortion/cracking/popping with my One in the car. When I'm streaming audio through Google Music or Pandora, there is noticeable distortion whether Beats is on or off.
I previously had an S3 and that worked fine. This morning I paired my work iPhone to the car and was able to play from the on device music without any distortion. Next up I'm going to try an aux cable to see if it's a Bluetooth or phone issue, but I wanted to see if anyone else had a similar experience.
I noticed major hissing with the beats EQ on. Turned it off and I don't hear it anymore.

I've got a 2013 Sonata with the Dimension navigation radio.
I suspect something related to Beats but I'll have to play around with it while not going along at 75mph.

Hmm, interesting. I'm assuming you're on the stock ROM?
Also, you said you still get the distortion even with Beats disabled, so do you think it's still Beats related?

Using Google Play Music in a 2013 Camaro and I've got no audio issues.
I just purchased the phone, but slacker worker flawlessly. Have not had a chance to try Pandora or other music apps yet.
Rush hour traffic this morning allowed me to do some additional testing. I found that Play Music is distorted with/without Beats and also regardless of how loud I have the Bluetooth output volume set. I don't have any full songs on the phone, so I opened the generic Music app and played back some of my ringtones. None of them were distorted coming over the radio, so I'm further puzzled about why Play Music would have such an issue.
I'm going to try Pandora on the way home to see if that is affected as well.
Another update: Pandora works great. Play Music is toying with me...

just got the phone less then 24 hour's and i had it crackle when i had it playing in my civc! it didn't do that yesterday, but today i noticed when i played deadmau5. maybe i had to turn it down one or two notches. maybe volume has something to do with it!

I've tried it as low as 50% on the volume bar. I'm thinking that the interference has to be with Play Music, Beats, and my car's amp. Or some combination of the two since my S3 did not have the issue, and my work iPhone plays just fine.

It's a [decent] stock system, so I'll have to check around for that info.
So now that I finally managed to phrase it correctly, there are a lot of other people reporting the same issue, and it appears to affect Sense ROMs due to the factory settings for the Bluetooth stack. AOSP does not seem to be affected.
https://www.google.com/search?num=20&q=htc+one+bluetooth+audio+distortion
I just got my HTC One from Verizon yesterday and noticed a horrible sound quality when streaming music through Bluetooth. I'm streaming to LG CM4530 stereo system. The distortion is just unbearable during high pitches. The problem persists regardless the volume in both the phone and stereo, the app used (tried Pandora and Play Music), turning Beats Audio off or even cancelling the EQ on the stereo system. I'm convinced that it's not the app because I just replaced my old and slow Droid 2 Global loaded with 2.3.4 Gingerbread and never had any problems with A2DP sound distortion. (Yes, ironic.)
Many point that the problem is on the stock HTC ROM, but I haven't hear of any fix so far. Any suggestion?
Sorry to revive an old thread, but have other users with the sound-over-bluetooth distortion issue found any way of solving it other than flashing an AOSP ROM?

Misterious audio problem

Hi everyone, before anyone complains I did search for the problem everywhere and found nothing so I decided to post it here.
I'm going straight to the point since the problem has been driving me mad for a long time.
The problem arises when I use the ear speaker after that the headphones output is totally distorted but not before. I've always managed to do a reboot and everything is back to normal until I use the ear speaker again and the problem comes back. Something strange is that I only notice the distortion on any headphones or headset but never with a speaker such as a bluetooth speaker or via aux cable to my car.
I changed the firmware to various versions (stock and custom), changed the kernel, changed some build.prop settings, disabled the equalizer apps, changed the music player, disabled the Nuplayer and the problem keeps coming back.
Any ideas ?
Thank you for reading, hope someone can help me I'd be really thankful.
No one had this problem ?

Yes, i had it many times also. I think sound doesn't distorts. The reason for that is audio effects (or any other effects) stops working so sound becomes plain with no bass and other things. Some times force stop audio effects works but reboot always.

I disagree because tried freezing the audio effects app and keeps happening, also the same installing Viper4Android

Bluetooth audio stutter/skipping

This is incredibly frustrating. I had none of these issues with bluetooth on my S8+ whatsoever.
So one annoying thing that stood out was the bluetooth on this device. It keeps skipping and stuttering tracks whenever I play it on my Bose QuietComfort 35. It's normal on all my other wired cans but I usually use the QC35 alongside my phone during commutes.
Just to clarify, I'll list down all the "fixes" that I've tried. Obviously NONE of them fixed, or even alleviated the problem.
Cleared cache (this one just doesn't make sense imo)
Removed battery optimization on my music apps
Turned off WiFi & Bluetooth scanning
Switch Bluetooth audio codecs
Updated to 4.7.6
and PLEASE... if you DON'T have this problem, do NOT post how you DON'T HAVE THIS PROBLEM here, I'm looking for fixes, not jokes. Thank you.
I also have a QC35 and I don't have any issue but I post anyway
Joking aside I'm using 4.7.6 and my QC35's firmware is 1.3.4 and using the HBC codec.
What's your bose firmware ?
What do you use as a music player ? (I'm using the default Google Play music)
And what do you mean my "It's normal on all my other wired cans" ? Why would wired headphones have stutters ?

Everything's the same as you except I use PowerAmp as my music player and SoundCloud for streaming (both stutters/skips as well). I stated that I didn't have this problem on my wired headphones just to clarify.
I notice the problem most when I'm commuting and I have mobile data turned on. It went even more haywire when I downloaded something on Google Drive. Hopefully it gets addressed with Android Oreo and the official Bluetooth audio codecs being implemented.
Oh bad me I read the you said it was normal to have stutters while being red... Night too short.
I'll trying PowerAmp to see how it goes.

I just said that switching Bluetooth codecs didn't work.
I'm having Bluetooth quality issues as well, particularly crackling and skipping. I noticed that if I download a file while streaming the quality will drop dramatically and the audio stream will crackle like crazy. I have tried all three codecs in nougat to no avail.
Should I upgrade to Oreo to get this sorted? Do custom kernels cause issues with the quality?
Thanks.
OnePlus 5t, theOne 7.1.1 (stock basically), viper4arise and Dolby
Update: when into EX Kernel Manager (specifically under the misc I/O settings), and change the I/O from ZEN to FIOPS. Not once has the music stuttered since, though I have only tested on SBC. If I get more results I'll bring them in.
Please note - I am on blu_spark, and I honestly do think it may have been the cause of the bluetooth skips/scratchiness. I turned off Dolby Atmos and Viper just to be sure.
Latest Oreo Beta build. Stream bluetooth, Pandora, iHeart and talk on the hands free no problems here. Lexus CT200h vehicle.
Would really check your cars manufacturer website. Most have a section where you can download latest firmware to a USB and flash your car to ensure you have the latest bluetooth firmware.
Working flawlessly on my car.
Anyone have any experience with the Oreo update?
Since updating to 4.7.6, I've experienced the following issues:
despite being connected to a bluetooth device, sound still comes out of phone speakers
static/distortion for a few minutes when initially connected to my car (2017 Chevy SS)
Upon connecting to car bluetooth, randomly the phone will call my phone number
I can usually fix these issues by either going into airplane mode for a minute or two or rebooting. Sometimes, I have to do this multiple times.
I've cleared cache but made no difference and I don't want to have to factory reset after every single update. Is it possible to flash factory images without nuking your data? You can do this with Google's Nexus/Pixel factory images.
I've got a different problem with 8.1 and BT audio. After upgrading to android 8.1, suddenly my car audio system doesn't receive songs data (artist, song, album). It's just display "no title".
Does anyone encountered similar issue?

Ugh, exact same issue. I don't suppose you're using a car with a UConnect system in it? Dodge, Jeep? All those crappy brands?
I am able to make phone calls just fine but I can't stream audio to save my f**king life. This happened right after the upgrade to 8.1 and latest update did nothing to fix this nor did it mention the issue. Has Oneplus even acknowledged the issue?
Im actually having the same exact issue, with Uconnect on a 2017 Chrysler 300s. Bluetooth skipping and sounds like crap. Have tried pretty much everything so far and no fixes
this what happen to me ...bluetooth to speaker klipsch ... sometimes got crack sound ...i mean wtf
Has anyone been able to figure this out? I'm still experiencing issues as well. OP5T and QC35.
I've been working OP support for almost 2 months via email and the cannot figure out how to fix this for be BT CALLS sound terrible,
I'm having problems with Bluetooth in a ford fiesta 2015. The phone is on 8.1.0 stock, no root. The device itself connects to the car perfectly, but fails to download the phone book, and says I loose signal when trying to make a call. The device registers that I've asked to call a certain person but nothing else happens afterwards.
I didn't have this problem on 5.0.4
