[One (M7) Q&A, Help & Troubleshooting] Jinra321:
So I reflashed ARHD8.1 without adblock and Pandora is no longer horribly stuttering. However it still has occasional stutters in both Pandora and Google Music. Still not sure what's causing it.

I reflashed without PureXAudio and the occasional skips/stutters still happens. Maybe once every couple minutes, really annoying considering this happened on my Note 2 also, which is why I bought the HTC One. I initially thought it might be a rogue app, but I don't have anything that could be causing it besides maybe groove IP disconnecting/reconnecting, or tasker. However I disabled both apps and the stutters still happen..
[One (M7) Q&A, Help & Troubleshooting] jskup:
In terms of Bluetooth, the largest thing that could change in the near future would be if we get an official 4.2+ or the rumored 4.3 release, as the BT stack is recoded in that code base. This has the potential to change the game, but really considering your issue still seems to be isolated to your devices and not everyone's though, I've gotta think we're overlooking something. The further clue that you are saying this happened on your Note 2 as well also makes me wonder what else is happening.

Is this stuttering possibly during PBAP, MAP or some other profile saturating the connection with its own traffic? Is this on all BT devices that you've tested against or are we dealing with a dodgy car kit/speaker instead of a phone difficulty?
[One (M7) Q&A, Help & Troubleshooting] Jinra321:
I dont use blue tooth, this is strictly wired 3.5mm connections. I don't have any uncommon apps besides tasker/secure settings/busybox/grooveip/xposed installer that were on both my note 2 and htc one. The only apps that have SU access are secure settings, xposed installer, seeder, solid explorer, betterbattery stats, and tasker.

I was almost sure that the stutter/skips were caused by purexaudio, but I guess not since I removed it.
[One (M7) Q&A, Help & Troubleshooting] youwonder:
I had this as well, does it sound like the stuff in this thread?:

http://xdaforums.com/showthread.php?t=2269581

I personally had it fixed when I flashed CM 10.1 nightlies, so I'm guessing it's a software issue, more specifically maybe even androidHD
[One (M7) Q&A, Help & Troubleshooting] Jinra321:
It sounds similar, sometimes the audio would cut out entirely for a third of a second, but it was not happening nearly as frequent as yours. Mine only happened once every couple minutes. Also I have since flashed bulletproof 1.9 kernel with purexaudio 4.0 and the problem seems to have gone away. However, more testing needs to be done..
[One (M7) Q&A, Help & Troubleshooting] yokken:
I'm thinking it has something to do with CPU usage, like it running a process in the background that disrupts the audio output. But I don't know if anything can be done about that.
[One (M7) Q&A, Help & Troubleshooting] paul_59:
That's my guess.

I haven't experienced this on my phone, but I did create this effect on my HTC one x when playing with system tuner app and lowering the cpu max frequency to a very low level, seemed to cause stuttering when cpu was overwhelmed whilst artificially slowed by my tinkering.

Can't think of an easy solution, except backup all apps to dropbox or pc, then install stock Rom without additional apps. See if cured, then restore apps one at a time to see if you can find the cause.
[One (M7) Q&A, Help & Troubleshooting] yokken:
Well, I had a stutter today with Beats off, so I know that's not the issue. I'll be flashing TrickDroid tonight and I'll see if it happens after that.
[One (M7) Q&A, Help & Troubleshooting] Saltank:
I have one or two stutters when I listening to something on Play Music. I thought it might have been something to do with it being synced over WiFi at some point, I'm just not sure yet.
[One (M7) Q&A, Help & Troubleshooting] dayze0:
Are you all up to date, running 1.29 software ?, try a different media player - with limit option set to on and increase buffer size and priority if your player allows, PowerAamp pro has all these options and seems to work ok for me , as long as I dont crank the amp right up
[One (M7) Q&A, Help & Troubleshooting] yokken:
Yep, running 1.29.xxx.16R. Didn't get a chance to try it on TrickDroid, didn't like the quick toggles and battery icon so I went to ARHD. Still happens on ARHD9.3. I don't feel like buying PowerAmp just to see if my audio stutters with it.
[One (M7) Q&A, Help & Troubleshooting] Grooby97:
no stuttering using 3.5mm headset

stutter using BT A2DP. Seems to be an antenna issue. If I turn my phone to a certain angle, in respect to my BT headset, then the stutter goes away.

Update: Enable my wifi router with Bluetooth coexistence and that resolved the stutter.
[One (M7) Q&A, Help & Troubleshooting] bludevil007:
Hi Guys, new to the forum, and am a new user of an HTC One. I'm having a similar issue, although I can't tell if it's identical. Every few times I use any music player (playerpro, google play or the stock music player), a song will simply cut off and then the player will start skipping through tracks - playing a couple seconds of each or stuttering through. I just switched from an iPhone and love the HTC One, but half of what i use my phone for is music playback, and I really dont want to go into ATT and return this thing.

I appreciate that this may not be the right forum to ask, but you guys seem to know your stuff....
[One (M7) Q&A, Help & Troubleshooting] Lolpoppa:

Ive just returned a handset to Orange (cos they're inept and don't know the difference between black and silver!) but I used it for a week and the audio playback stuttered across the board whether it be stock player or Poweramp Pro, mp3 or .wav, Beats on or off.

Everything was stock cos I hadn't rooted knowing I'd be returning it but it's a bit disconcerting and has left me wondering whether to replace it with summat else.
[One (M7) Q&A, Help & Troubleshooting] yokken:
I have Bluetooth and NFC off and it still does it while streaming through Play Music @ 320kbps without Beats on, ARHD9.3. I really don't know what the issue is. Maybe kernel-based... I dunno. It's not infuriating but I still wonder why it happens, since flawless audio playback seems like something that everyone has had for the past 5 years. Guess not?
[One (M7) Q&A, Help & Troubleshooting] bludevil007:
I've downloaded the WizDroid blocker because I know this problem only happens when the headset is plugged in. Even if this works, it's sort of annoying that this is what you have to do to get a music player to work.

In any event, I will report back over the next few days to see if this works. If anyone has any better suggestions, I'd be grateful.

Slight stutter

Hey all,

I've no solutions yet. But have the same thing going on with my UK (O2) HTC One.

It's a very quick stutter (split second) and only happens once at a time. The re-occurance is sparatic.

It's not app specific. I have only noticed it with headphones (though I haven't tried BT yet).

That aside it's a great phone, but the sound's a big deal!

I'm waiting to hear back from HTC to see what they suggest. :eek:
[One (M7) Q&A, Help & Troubleshooting] ArmedandDangerous:
If this is like anything on the HTC One X, then the SD read ahead setting is the culprit. Set it at the minimum and the stuttering goes away. Someone try it out and see if that works (rooted of course) :)
[One (M7) Q&A, Help & Troubleshooting] Amrut223:
Also have this issue. I can be listening to Pandora and it stutters here and there. With this and the light leak near the home button and long charge times... My S4 is looking more and more like my daily driver.

But the sound is so dam good on the One.... :(
[One (M7) Q&A, Help & Troubleshooting] yokken:
Where might this be changed? In something like SetCPU or FauxClock?

Will it degrade IO performance?
[One (M7) Q&A, Help & Troubleshooting] uinmack:
Thanks, I gave it a go. But it seems to already be set to the min (128).

Am missing something like needing to change kernel?
[One (M7) Q&A, Help & Troubleshooting] wengole:
After spending a few hours trawling the internet and reading this entire post, this was the solution.

I installed Trickster MOD and set the Read Ahead buffer to 4KB and also set the scheduler to deadline.

FYI I'm using rooted stock with Bulletproof 1.10 kernel.
[One (M7) Q&A, Help & Troubleshooting] ArmedandDangerous:
So it WAS the read ahead then ;) Glad you fixed it. Now for others to try and see if it helps them :)
[One (M7) Q&A, Help & Troubleshooting] wengole:
Dammit. Spoke too soon. It is still happening. Still completely sporadic. However it does seem like each stutter is "shorter".
[One (M7) Q&A, Help & Troubleshooting] ArmedandDangerous:
Is 4KB the smallest value? Might want to experiment with lower/higher and see what works best :)
[One (M7) Q&A, Help & Troubleshooting] wengole:
128B was the smallest and default. My theory was increasing the buffer (as default was lowest) might help as there would be less IOs if that is indeed causing sufficient latency to be the culprit.

Have left my settings but also disabled AdAway and installed PureXAudio 4.0. Not very scientific I know making lots of changes at once, but I prefer to make lots of suggested changes to fix it, then disable one at a time.

AdAway I highly doubt to be the culprit. Firstly no-one has provided a reason as to *why* this could be the cause and secondly all it does is edit the /etc/hosts file. This is a static file read by the OS when trying to resolve a hostname.

Why are *all* music apps trying to resolve hostnames/using the hosts file at all?

How is reading the hosts file causing sufficient lag to cause audio stutter?

I've also read that people don't have this issue at all when using AOSP based ROMs. Now this provides 2 clues as to the culprit.

AOSP has no HTC software - maybe there's something running in Sense that's causing this?

Most AOSP ROMs (all?) are now running 4.2.x Android. This has many performance enhancements in the core OS. However as people have stated in this thread, considering we've had "flawless" audio for years, it's hard to believe this is a fundamental Android problem

My conclusion thus far is that it's HTC's fault with some Sense crapware. Hopefully for those of that want to stick with stock based ROMs this issue will be addressed in an OTA update and that will trickle down to other ROMs. Otherwise if like me you prefer AOSP, then I think waiting for the Google Experience ROM to become available at the end of the month is probably worthwhile.
[One (M7) Q&A, Help & Troubleshooting] yokken:
I also have to wonder why editing the /etc/hosts file would have anything to do with micro stutters in audio playback. My only theory is that something is filling a buffer to the point that the audio cannot be streamed flawlessly, so it stutters for a split second while it fills the buffer. This is probably due to memory management within Sense. I'd like to report this problem to HTC, but I don't know who I'd contact about it.
[One (M7) Q&A, Help & Troubleshooting] lloydcabraham:
Had this problem when i was using any app that used the front facing camera such as the ones that turns off screen when covered, or app that holds screen on while looking. Music stutter went away when i disabled any services that pinged my front camera.
[One (M7) Q&A, Help & Troubleshooting] yokken:
I don't have anything that pings my front-facing camera and it still occurs. It's pretty infrequent now but it's still there from time to time.
[One (M7) Q&A, Help & Troubleshooting] yokken:
I can cause stuttering by opening certain apps. It just happened when I opened Snapchat. It's got to be a buffer thing, or a mis-allocation of CPU cycles. Something that prevents the audio from having a flawless stream, something interrupting/stealing its priority/CPU time.
[One (M7) Q&A, Help & Troubleshooting] uinmack:
I just uninstalled adfree, and after a restart the stutters are definitely reduced. But not entirely gone.

Thanks for the tip!
[One (M7) Q&A, Help & Troubleshooting] yokken:
Adblockers basically increase the amount of hostnames the OS has to check any time it makes a web request. This would increase CPU usage in the background, so I can see why removing them would lower the amount of stutters. I just wish there was a bona-fide way to fix this.
[One (M7) Q&A, Help & Troubleshooting] ArmedandDangerous:
Somehow this only happens on rooted devices with access to kernel settings.
[One (M7) Q&A, Help & Troubleshooting] yokken:
Hm........ maybe we could compare all stock kernel flags with modified kernel flags and see what might be causing it?
[One (M7) Q&A, Help & Troubleshooting] uinmack:
ARHD 11.0

I've now moved away from stock & installed Android Revolution HD (11.0) with Pure Audio enabled. I haven't had any audio problems since.

It uses the stock kernel, and seems to have the same read ahead (128) as stock.
[One (M7) Q&A, Help & Troubleshooting] yokken:
Interesting. I'll be sure to try that out!!
[One (M7) Q&A, Help & Troubleshooting] yokken:
Edit/bump for anyone interested: I have not encountered the stutter AT ALL in ARHD11, with the PureXAudio enabled. I tested with Beats on and off. Looks like 4.2.2 fixed it. Thank you HTC!!!!!!!!
[One (M7) Q&A, Help & Troubleshooting] jmmurray:
Having the same stuttering issue with my HTC One from TMobile. It's on Android 4.1 still as we all are.

I've noticed it's related to bluetooth in my situation. I'm using a 3.5mm jack to my car stereo as the bluetooth quality in the high and low end is terrible anyway. When the phone is connected to the car for phone use the stuttering happens over the wired audio. When I disconnect the bluetooth, even though the bt antenna is on in the phone, the stuttering stops. Wifi on or off had no effect on the stuttering.

I'm not sure if the new bluetooth stack in 4.2 is going to resolve this. I'm hoping to find out in the next couple of weeks.
[One (M7) Q&A, Help & Troubleshooting] themaha:
Fixed

My issue was resolved when I upgraded to a newer version of JellyBean, 4.3.

I can't say for sure what fixed it, but it turned out (at least for me) to be a software issue.

Currently running Stock with Goodies One 2.0 on a Sprint HTC One.

Don't forget to hit thanks if this helped you.
[One (M7) Q&A, Help & Troubleshooting] xandrake:
I'm running ARHD on my HTC One and have horrible stuttering issues in my BMW (2014 iDrive unit). The music will play fine for 2-3 minutes then stop for 3-4 seconds and sound like the 'seek' feature of old CD players from the 1990s (fast skipping forward) until it reaches the point it was supposed to be.

I have tried the following:

- Reboot

- Wifi Off

- Bluetooth radio on then off

- Deleting and then repairing devices

- reflash of ARHD

All with no joy.

What I am hearing is not a constant tone like some of you. I had that problem in my old car when something was charging via AC charger. A ground loop isolator fixed that issue immediately. If any of you do experience the continuous odd tones and have something charging, this may help you. I used to drive a Mazdaspeed3.

Hope this helps someone out there and I hope someone else is experiencing issues I am with a possible solution.
[One (M7) Q&A, Help & Troubleshooting] uinmack:
I think this is a problem with the BMW's and the Bluetooth version that they support.

Extract the apks from both zips and put them in your phones system/app, be sure to change the permissions.

And also put the lib files in the system/lib and change the permissions.

I didn't flash them in recovery as I don't have a recovery installed, if you have a recovery installed you can try to flash them, though I wouldn't recommend doing so as I don't know if the zips will work on our phone.

If you do want to install it in recovery I highly recommend making a backup.

[Xperia Z Themes and Apps] tatit1011:
You go into settings, then language and input.

Tick the boxes for the android keyboard and iwnn ime keyboard.

Go in the settings of the android keyboard and then scroll down to the bottom and go into advanced settings and tick the box that says switch to other input methods.

Set the default keyboard as the android keyboard and after that disable the xperia keyboard then reboot.

After that your keyboard should now be the default aosp keyboard and everytime you press the globe it would turn into the emoji keyboard.

Hi, some time ago I bought 2 pairs of Philips Black Surround Sound Headphones for mine and my daughters mobile phones (HTC Wildfires S & HTC Desire).

Now I've upgraded to a Samsung Galaxy S3 Mini I've discovered to my disappointment that neither of them work for making/receiving calls on my new phone, but only work for music. But what I have discovered is that I make a call without the headphones plugged in then plug them in whilst its ringing without any problems but unfortunately, I have to remove them and plug them in again to listen to music.

Does anyone have any idea why this is?
[General Questions and Answers] Caniv:
hey guys!

i've only had 2 smartphones till now, Defy and N4... which i love.

my mom just got the i9500 and it might end up mine.. so i wanted to use this opretunity to ask.. what "features" or actions are via rom and what's via launcher..

for example, if i like my icons to be smaller, with/out text, more slots change the rows and colums number on my home screens, change if homescreens are gonna go 123123 or like wall-123-wall (meaing i cant circle through em) all of these features are they Rom or Launcher?

and whatever they are, what is the other thing responsible for?
[General Questions and Answers] illhangon:
Both are two very different things. All the things you mentioned above are by launchers.
[General Questions and Answers] orangekid:
All of the home screen UI stuff is Launcher stuff. If you use Apex or Nova or something you get more options like that.

Things like changing your system settings would be the "ROM' stuff you're talking about, although those are limited if you aren't rooted or on a custom ROM.
[General Questions and Answers] Caniv:
ok awesome!

the reason i asked is becasue my N4 has Slim + Apex and i REALLY like the way the icons are small (no idea how i did that btw) and all of the appearence settings, and was worrid i wouldn't be able to do that with CM...

Sweet update. I always ran 1.5gigs+ of RAM and have noticed the occasional lag spikes this phone has (especially with live wallpapers), this update brought me down to 750mb of RAM. I'm hearing you can re-root after so there really is no disadvantage to this update.
[AT&T Samsung Galaxy S 4 General] cybershawngates:
actually more ram use might mean its caching better. Android memory management is a strange thing. I used to use a task killer to "free up" more memory on my old phone but that actually made it slower.

I think there is a gray area where the system should cache some of our apps. But not fill the whole damn thing up! But not cache anything at all either.

There should be a middle ground and Samsung should just run some performance test and see where we get the best response times. I really don't get how they do their testing.
[AT&T Samsung Galaxy S 4 General] KryptosXLayer2:
Let's not get too carried away - first, if this were "the best update ever," it would have included an unlocked bootloader, and since it did not, it IS not the best ever.... second, there certain is a disadvantage to updating right now, it has not been confirmed or denied that this update has in fact patched the exploit Dan "THE MAN" has created, and to quote him directly:

So it's not the best thing to tell people who aren't familiar with this stuff to update away - yes, you CAN Odin back to the original firmware that was originally released and no, it did not blow any q- or e-fuses, but it still isn't recommended by our fearless bootloader unlocker, so I for one and holding off
