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

Music Player Problems

hey guys, currently running 1.29 on my unbranded HOX.
Noticed earlier while listening to my music through the stock music player that the songs kept semi skipping for a couple of seconds and the music sounded very, how to put it, crackly and popping, has anyone else had this problem?

It's been posted a few times I believe its to do with beats.
Sent from my HTC One X using xda premium

Yeah I have read about beats but I thought the problem being discussed was full songs skipping, also thought 1.28 was supposed to have fixed it, hopefully HTC can sort it out! I'm no audiophile but its damn annoying.

I have it to. First i thought that is was my headset now i read its the phone on 1.26 i never had probs
Sent from my HTC One X using XDA

i had this too. the 1.29 update seems to finally have fixed it.
that or that i am now using ubermusic with beats enabled

Hello. 1st time posting, new Android user.
I have the very same problem and it seems to be getting worse. It's definitely to do with the phone adjusting network, as when it's in airplane mode it doesn't happen at all. As I travel on a train that goes along a coast line, in and out of tunnels - this is really getting to be annoying.
I'm using both DoubleTwist and the stock music player, happens with both EQ/Beats on or off.
I don't really want to buy another music player

But if ubermusic really solves the problem then I might look into it.
Also happens when watching vidoes inc. streaming video.
This really is a bit of a joke - "Authentic Sound" they said. So far it's about as authentic as an old walkman. I'm smitten with the phone in general, but this is unacceptable.
Maybe there's another fix. Perhaps a 3rd party app conflict? Any ideas?
1.29.401.11

I have this probelm as well, I thought it was my bluetooth headphones until I connected my wired headphones and the problem was still there - Poweramp is better than the stock player. Will try ubermusic tonight and see if that helps. The Galaxy nexus had this problem but was sorted with an update - hopefully HTC will do so too - quickly.
I am on 1.29...11 by the way.

remember android has a 15 minute period in which you can get a refund for an app - if it doesn't work open the play store for ubermusic and the buy button should have changed to a refund button.
(ubermusic is also skinnable, i didn't like the default but the ics style one is nice)

beats won't be "authentic sound" - music with no EQ applied will be the most authentic. but i get the point!

Exactly, it seems to be not just the network coverage, but any notification coming while the music is on.
Happens to me while traveling by subway, the network coverage is only in stations, not between them, and the music starts skipping right away after leaving/before getting to the stations. Also if the network coverage is OK (outside) but you get a notification from calendar, music crackle the same way.
Contacted HTC support and they replied to me to get a replacement device from my reseller...

Bit of an update on this one.
I checked what apps were running in the background - to see if there was anything I could kill to see if it made a difference.
I noticed the widget for SeriesGuide was running, despite my not using the widget or the app for a long time (I had rebooted the phone on occasions since not using the app).
So I uninstalled that application, cleared all cache using ES Task Manager and shut down the phone (not reboot). I heard that a restart could just solve the issue anyway.
Hey presto, no cracking audio or video so far - (that's 3 1hour train journeys).
I'm not entirely 'blaming' SeriesGuide, it may have been anything - but it's worth checking whats using resources that isn't running - I'm sure many of you do this anyway.
One interesting thing is, I was browsing the net or something last night on the couch, just using the phone - when I noticed it started to make pretty audible pops for no reason - about 5, and then nothing. No problem on the train this morning though - so for now I'm happy.

Install poweramp and problem disappear
Inviato dal mio HTC One X

I tried Poweramp - despite not liking it, it didn't solve my problem.

Service repair
Sent my HTC One X to service repair for diagnostics and the final statement is - faulty motherboard. Anyone having issues with crackling music player either when the network signal is lost or when the notifications pop up, go and return your phone.

Well, since my last post explaining what I did to remove the crackle, I've had none at all.

Bluetooth A2DP stutter cuts out while streaming music

I have noticed since I upgraded from GS3 to Note 3 that when I am streaming music to my car stereo the audio will skip or stutter. The song continues to play but the audio cuts out for anywhere up to a second or two. Has anyone else seen this or resolved it?
I have seen some posts that say turning off WiFi fixed it but I still get the skip, if a little less frequently with WiFi turned off.
It seems to go away if I set the developer options to keep the screen awake while charging. So it seems like the CPU clock may be too low during sleep to maintain everything else it is doing as well as audio streaming.
Any feedback is appreciated, thanks!

This happens to me too sometimes. It seems worse when I first start streaming & then it calms down a bit. But it still occasionally skips. I experienced this on my note 2 as well though, so I don't think its an exclusive issue to the N3.

This is happening 4 or 5 times per song, so it is quite annoying LOL

Stock ROM? Stock Kernel? Need more info from both of you.
Sounds like the CPU might be dropping too low when the screen is off, causing the stuttering. You could try a custom kernel with a higher screen off frequency.
Used to happen on my S2 and this was the problem...

Full stock, I believe that is the problem as it is pretty much resolved when I leave the screen on. Still testing this here and there to be sure.

This has happened to me on every rom & kernel I've tried. Which is pretty much all of them for the N3, and everything from stock to CM on the N2.

I have the same problem on my GN3 international version and yes leaving the screen on WILL solve it. However, that's not a practical solution.
Try this, download Poweramp, go into settings, audio, advanced tweaks, set the audio buffer size to Large (+250ms) and audio thread priority to +2
See if that works for you. If it does, then buy the full version even though I like the timbre effect and bass on the stock music player but this is the only solution, so far.

What headunit? I run Kenwood KDC-X995, and never had an issue with it cutting out. THe headunit wouldn't display track info though. The way I fixed this is connecting via the Stock Samsung media player., Everything has been a dream since

I had this problem and it just went away after a few reboots and some time. ..

A2DP loss
Note 3 Owner here. Rooted with stock ROM and stock kernel. (T-Mobile)
Experiencing intermittent Bluetooth audio loss as well.
Just contributing to the list.
-Steven M

BTW, what player are y'all using? In power amp there is an option for keep service awake if music.stops while.playing with screen off. And there is also option to use a wake lock also. I am not having any problems nor have I ever so I can't help. The only other suggestion I have is maybe your radio Bluetooth sucks. I went through a period of testing many Bluetooth headset and receivers a couple years ago. Needed something good to listen to my music while I rode my bike. Many of the Bluetooth I tested were very sensitive to the bumps and vibration while riding hard on my mountain bike. The only solution for those were to put receiver right next to my phone. Being in my pocket was too far away or something. I ended up sticking with Sony mw600 as all purpose. It could take any headset, and I was able to use it as a receiver in my truck as it didn't have Bluetooth. Now I also have a Honda civic with built in Bluetooth and all is well. My Sony mw600 oled stopped working though so in on lookout for a nice apt x receiver.

I am using a Sony DSX-S300BTX and have had no previous issues with my HTC Sensation 4G or my Galaxy S3. It only started when I got my Note 3. I use Google Play Music with the All Access service.

Just an update on this. Over the weekend I did a factory reset and this time I did not let it restore settings and apps from my Google account. I went through and installed all the same apps i was using before. And so far I have only noticed 1 stutter/cut out since then. And if I am correct, this only happened when I was leaving my house and it switched from Wifi to 4G LTE on the stream.
Will continue to monitor and see if the issue comes back. But so far I am rather happy.

I came from the Note 2 to the Note 3 and I'm fearing that it's 4.3 that is causing the bluetooth intermittent issue. Whether or not I stream from Pandora or my music player, I get the stutter. Doesn't matter what ROM I use between hyperdrive and beans too. Someone said it could be the adblock that is causing the stutter but I don't have that installed at all. Getting pretty frustrating.

Ended up not working for me,...but keeping the screen on did seem to eliminate the skipping.
Wonder if there's anyway to force Bluetooth not to sleep,....

I ONLY get the stutter when using the stock music player. It never happens when using, for example, TuneIn Radio.
I exchanged 2 Note 3's. The first one had the stutter problem so I returned it. The second one had NO stutter problems but overheated from time to time, exchanged as well. The third one doesn't over heat but, unfortunately, has the stutter problem. So, I just gave up. The PowerAmp solution works for me, though.

Sorry to hear it didn't work for you.
Someone mentioned increasing the minimum CPU frequency and that would solve it. Try upping it to 400Mhz see what happens but this will definitely drain your battery more than usual.

The same thing happened to me on the note 2.... actually the n3 isn't as bad as the n2 was. Fwiw
sent from my ??????? note 3?

SO I have started to notice that it isn't actually the stream stuttering, but a short disconnect of the bluetooth. I noticed that when the music cuts out, it also drops the media connection to my car stereo, in that the artist and song title disappear until the connection comes back. Seems like a bad bluetooth stack or something as I tested a Nexus 5 and do not have this issue at all. And I never had a problem on my GS3.
Hopefully the 4.4.2 update will resolve this issue. Whenever that may be...

I have this problem as well, (stock rom rooted, stock kernel) I use power amp. now however I cant stream my music through bluetooth at all, but when a call comes in, it streams. Doing a little digging into my phone, my N3 seems to think im in a call, and only plays my music through the speaker for your ear. it only started a few hours ago. even when I am not connected to bluetooth, it still plays music through the same speaker. tried uninstall reinstall. I did update apps earlier when I got home (ove wifi). once they were done, that seems to be when this issue started.
any help/suggestions?

Bluetooth music stutter

I've had some stutter with music playback through my bluetooth speakers. I have 3 and it happens with all of them. I have a subscription to Spotify and noticed it there. I tried Play Music and it stuttered too. I put a few albums on the phone to see if that made a difference but it didn't. It's not bad, just here and there but enough of a problem that I'm not going to put up with it. I did a reset but that didn't help. If it's a bad phone, I'll return it. I would think if others have had a problem I'd see someone commenting on it. Has anyone listened to music via bluetooth and had either an occasional stutter or a smooth experience? I've used the speakers with my Moto X and they've been good so I know they are ok. I appreciate any comments. I love the phone but need my BT tunes.

I've never used Bluetooth and have not had an issue here or there. It happens with every device out there. It comes with the territory of using Bluetooth.

I have to disagree, my xperia z3 was awful for this. So far I have not had any issues with my Pixel XL and I use it for my 1 hour commute twice a day aswell sporadically throughout the evenings/weekend. Could range be an issue for you? or perhaps a crowded 2.4GHz band?

I have the same issue. I just assumed it was the crappy headphones I use. It happened on the 6p I had. Seems it happens mostly when I put my hand on the glass window like I'm causing interference

Thanks for the reply, my phone is a few feet from the speaker and there is a stutter every few minutes. I'm at home, not a lot of network traffic. Apparently not a problem with others judging by the lack of comments. Thanks again.

If you have any xmas lights or similar (we have decorative LEDs) close to your speakers or between your phone and the speakers these can have an affect. I had to move my WiFi hub last Christmas as the Xmas tree was causing havoc!

Listening to music on BT headphones.
I've got a Huawei watch attached over BT. As long as I don't add a 3rd device playback is fine for me.
If I add a 3rd device, typically either a Mac or PC (e.g. Surface) then every 30 seconds or so there will be a stutter. Even though those devices aren't sending audio, there is enough chatter to cause an issue.

Yep - BT audio skips with my BT headset and 3 different BT speakers. All of these BT devices worked perfectly with previous phones, and I listen to music quite a bit, so it's truly a accurate comparison.
I have contacted Google and they have only suggested the most obvious things - none of which had any affect. Tossing cache, tossing all pairing and re-pairing. Latest was a Factory Data Reset and I just don't have the time for that now. Other Pixel owners report that same BT issues - some with pairing (which I don't have) and skipping/dropping signal.

I've found that 2 of the 3 speakers I have stutter, the ue seems to be OK. My son's Pixel had the same issue so it's not a bad phone. I guess I need to decide if I'm going to put up with it or not.

A cheap chromecast audio would fix this for you

I've noticed similar issue. Bluetooth stuttering. S7 never did it. Pixel xl does. Reboot phone fixes it for a while.
Might be Spotify memory leak. Not tested if Google Play also does it but will test that.

Same issue here with the bluetooth in my car

I have noticed the same problem a couple times, I cannot pin it down. I though it was the speaker, which is a fairly cheap one. I will test it more and see if I can find a pattern?

I just think BT for Android needs to be worked on. Same behavior on Nexus devices.

As someone pointed out a while ago, turning off wifi seems to stop the stutter. That causes you to keep an eye on your data use though. Hoping for a fix.

I will try that but I stream music a lot, that would seem to run up a lot of data.

Yea, that's not a very good solution.

My old headphones were BT4.0. the new ones I just got are 4.1. so far my newer ones dont stutter when I cover the glass. I still get some stutter here and there but i think that's just interference.

I have not experienced any issues with stutter or connectivity when streaming to my Lexus GS and paired to my LG watch - while using GPS/Navigation/Waze. I came from the HTC 10 which had MAJOR issues with this combination.

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 think it has something to do more with the connections. It goes even bonkers when I'm moving around rather than laying in one place.

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
