Stutters in audio playback every few minutes - Touch HD General

I am playing some music recorded to .ogg, using either Pocket Player or Coreplayer, but every few minutes (about 4-5 minutes), there is a little stutter during playback. It is very annoying and destroys my enjoyment.
I agree that the tracks are long (around 20 minutes) and the files are therefore large, but I have tried to increase buffer size for the players, but it seems to make no difference.
Has anyone got some inspiration for me?
thanks

I've also noticed similar minor "glitches" in the audio playback, but when playing .M4A files (similar to AAC).
Anyone else noticed this? I don't know if it also affects MP3s.
Ideas, anyone ?

Hi,
I am also facing this problem any resolution?

Yes.... this problem happens with Mp3 also.... who could think of it. It can't even play music without stammering... lets not get started on video
BANE

I have tried the basic guide to enhancing performance at
http://forum.xda-developers.com/showthread.php?t=446366
and it seems to make no difference - the stutters are still there. I thought it might be related to doing a Send/receive in Messenger, but it doesn't seem to be.
This is real downer on my experience of the HD, as I was expecting it to be the ultimate communication/entertainment all-in-one device. Not so sure now.

I don't think optimizing performance has anything to do with this. I mean, playing audio is NOT a demanding process. My old xda2i used to play audio without hassle....
There is something else that is responsible for this skipping in audio on the HD, I just can't figure out WHAT.
BANE

Same for me with MP3 using PocketMusic player, hopefully will get some updates soon... Then hopefully the HD will be more of what we all wanted!

Excuse me if this is stating the obvious, but I would urge everyone experiencing this problem to be sure to REPORT IT to HTC.
If there is no obvious solution and it requires attention from HTC developers, then we can't expect them to fix it unless people actually tell them about it, preferably quite a few people !
Thanks,

I have to say that I haven't experienced this even once. And I should be seeing it more than anyone, because I listen to audio books on my Touch HD for a total of about 80 minutes every day during my commute. My files are MP3s that are up to 8 hours long (100+ MB in some cases). I use Pocket Player 3.7. Never happened to me even once so far.
That stutter was exactly what was happening to me on my previous Windows Mobile phone, the AT&T Tilt (HTC TyTN II). It was like a half-second pause (not a skip) every once in a while. I was seeing it with Pocket Player 3.7 and with Audible.com's own player (possibly using the libraries of Windows Media Player) on that device.
In fact, one of the things that I like best about my Touch HD is that it cured that occasional pause problem for me when listening to audio books.

Interesting.. It would probably be less noticable with speech, though.
In my case, it's more like an occasional discontinuity in the tempo of the music, perhaps like a tiny fragment has been skipped. I only notice it every few minutes, but then again because the sound quality is generally very good, it's an annoying artifact in an otherwise pleasant listening experience.
I'm using the same music files that played back OK on my old PDA, so it can't be the fault of the files. I've not got any other fancy software loaded that might upset it, either.

That's probably true. There are more silences between sentences and, sometimes, words. That increases the likelihood that the stutter might coincide with one of those, which reduces my likelihood of noticing it. On the other hand, what are the odds of it always having coincided with those occasional brief silences in the audio book, in my entire two weeks' worth of audio book listening (easily over 10 hours) since I got the Touch HD?... I've never noticed it even once, while my similar stuttering experience on my Tilt was fairly obvious and annoying on a regular basis.

I have the same problem in all music players. It IS annoying. I have read in the Touch Diamond forum that they have had the same issue from day one. My Prophet and Trinity never had this skipping issue. Maybe a future rom will fix it.

Interesting thread here.. havent noticed anything so far on my HD..
testing it now to see if it accures!
will tell you the results in a bit

After aprox. 20mins of mp3s all is smooth without problems!
Guys i dont know why you have this annoying glitches.. i have no problems with mp3s or what so ever.. (using TF3D player)
the sound quality from the HD to my Creative Aurvana is just superb! i cant see why some people complain about the sound quality!
(get a decent pair of headphones maybe?)
here are is the info of my HD:
ROM: 1.14.40.1.3 (22273) WWE
ROM date: 10/24/08
Radio: 1.09.25.14
FYI as we all do.. i added a lot of programs and tweaks to the device so its not "clean"
as it was out of the box!
hope you resolve this issue.. but my guess its just a small bug in some rom builds?

yes this is a bug, and a bad bug too, it makes listening to any track really irksome. It has that sort of effect, where you sit there just waiting for the track to stutter.
the funny thing is that the stutters occur between 4-5 minutes apart. There must be something to that, the processor must become occupied at these regular intervals.
I think the obvious point, as someone pointed out above, is to report it to HTC - what they will do I have no idea, they normally don't answer my bug reports other than a formal receipt.
It seems from the posts here that this is definitely a problem. Perhaps another class action to make some action? The HD is now useless to me as a media player ...

I have the same problem too, I thought I was the only one.
I will try a hard reset and play some audio files to check if it is related to some piece of software installed on my HD.

i have the same problem, i am using mp3 at 320 kbs without conversion with the manilla player...the stutter is really a fraction of a second, but it is annoying indeed.

Music playback issues: quality/noise, stutter

Hi all,
I got my Hero on Monday and I'm blown away by this phone so far!
The only not-so-great aspect I have found is the music playback:
1) There is a small amount of background noise when playing music, which is noticeable
in a quiet environment during low-volume parts of tracks. I don't always listen to Metal on the subway, so this is kind of a problem.
2) Sometimes, when listening to consecutive tracks of an album, there is a stutter when a new track starts. Haven't found a way to reproduce this reliably yet.
I was expecting to be able to ditch my iPod for the Hero, but I'm a little hesitant now. Does anyone else experience these issues?
I have the same issue with the jumping at the beginning of a new track, haven't noticed the background noise though probably because I do listen to metal.
Maybe it has something to do with standard sd card or how the mp3 was created? I hope someone knows the answer.
Also:
Does anyone know if there is a graphic equaliser somewhere? Music seams to be too trebley (using Seinnhauser earphones), but I haven't been able to find anyway to adjust it
Forgot to mention: I used 192 kbit/s MP3s encoded by iTunes and portable AKG headphones. I'm going to try out the included earbuds when I get home, to see if they "equalize" anthing.
I'm listening to Rufus Wainwright's Hallejuah on my Hero now over a set of Sony MDR-NC22 Noise Cancelling Earphones (in-ear type) with the noise cancelling switched off. No background hiss. Could it be from your MP3?

That's possible of course, but I never noticed noise like this on my iPod. One other thing I'll try at home is listening to a WAV file and check for noise.
Send me the MP3 file and I'll load it up on my device now and let you know if I'm having any problems
my email address is my username @gmail.com
Ok, I tried the included earbuds, and the noise is much less pronounced than with my AKG headphones, but still audible. It starts as soon as the playback begins and stops about 2 seconds after I pause the music player. (I guess this is when the audio hardware shuts down.)
MP3 and WAV exhibit the same noise, so it's not encoding artefacts.

Is it a buzzing noise?
I'd describe it more like a hissing sound.
Edit: I have attached a sample MP3 (hissingat5.mp3) in a ZIP file. I can clearly hear a hissing sound around 0:05 when the music gets quiet and I'm not using the included earphones. Anyone else? (I've checked the original CD with the same headphones, there's definitely no noise on the recording.)

My ipod touch does this sometimes. I have to reboot the ipod and its fine after. Maybe its because they are low on memory. Have you got lots of apps running? Try taskiller and try again?
I've found the music app struggles the most with low system resources and during the phones numerous "heavy lag" periods makes play back shutter or even stop altogether!
And god forbid you have more than five albums with bog standard 600x600 cover art... slow doesn't really describe it

Good idea, that might be a reason.
I think I'll be sticking to my iPod for now, though. While the stuttering problem is probably fixable in software, I'm not so sure about the audio quality.
my music also lags(espacially in sleep mode.. it's ridicoulis)... it's so annoying.. something needs to be done about this... I've tryed to memory cards and the music lags on both.. one is fast and one is slow..
I've found that if I play music through the phone itself or my headphones, there's no problem. If i connect it to my little 2.1 speakers, songs stutter, jump, restart, skip etc CONSTANTLY. Any ideas why this could happen? The speakers work fine with everything else, afaik. And the Hero works fine with other stuff... guesses?
I also have the slight hiss for a few seconds. Sound quality is pretty average, but i have my awesome samsung P3 for that
Im using a Philips SHB9000 stereobluetooth headset, theres no hiss in that, maybee its bound to wired only? thoe i have some stutter.. i use a Class 4 4GB Microsdcard.

Yeah, since you're not using the Hero's audio hardware at all, I wouldn't expect there to be any noise.
BTW, how much does the bluetooth headset drain the battery? I was thinking of using one to solve this problem.
Lack of gapless playback is also a bummer for me. I might be going back to my Zune.

Exactly the same as on my phone. I'm on my fifth Hero now and knew about the hiss already but this is the first to stutter. Exactly the same files, exactly the same memory card, exactly the same apps installed and running on the system.
No idea why one Hero has difficulty and others don't.
My Hero stutters even in the middle of songs on playback. I tried an alternate music player (nswPlayer) and it didn't help. I'm using mp3s but I think they're 320kbps. Maybe a re-encode would help?

Update for HTC HD2 Music Stability

This update for HTC HD2 HTC Sense enhances the stability of the music application so your enjoyment of your music is no longer interrupted by the player behaving unexpectedly.
Installation Instructions:
Note: This update is only applicable to ROM versions equal to 1.73.xxx.x, or lower.
http://www.htc.com/uk/SupportViewNews.aspx?dl_id=938&news_id=637
Installed without problems. I had very few 'stability' issues with the music app to begin with, so it'll be a while before I'll be able to tell if it improved anything.
And yeah, dammit, you beat me by a minute!
http://forum.xda-developers.com/showthread.php?t=671207
what changes does this actually make, htc are always really vague saying what a patch does. does it by anychance fix the library reloading everytime
From time to time playback freezes for a few seconds - pretty rare but annoying - maybe this will be fixed.
Or maybe this is how HTC describe the annoying problem where Audio Booster does not automatically kick in when starting playback for the 1st time after a reboot?
the music player is always lag. unlike iphone player which is alot better
That's true, Music Player lags a lot... mainly after a couple of days without switching off the telephone and after an intense use of the player (2-3 hours)..
I hope this hotfix will solve those problems...
Does anyone has any feedback about it?
I wonder if there will be a hotfix for TMOUS, It lags so much i just dont even use that tab anymore

Can someone post this cab, it dissapeared from HTC support site
using artemis v9 rom. 16gb card. much faster near instant load and scan of 12mb of music takes 20 secs from several minutes.
Whoooha - /WIN.
No lag (stop in music after every 10 seconds) any longer when putting device into sleep pushing power off once.
Old Work-around to push and hold power off and let it go to sleep from the screen with 'shut down' menu is now absolete.
After this fix just find your music, push play and one-hit power off to let it go to sleep and music plays perfectly.
Super upgrade - waaaaay to late - but glad its fixed!
Kindly

Audio booster is still not working
As my title, the audio booster is still not working properly after this update. It seems to cut out every time there is a drop in network connectivity.
This is a great shame, because for me it prodcuces the best audio output when combined with SRS WOW.
I am using S2P until audio booster is fixed, because bass level-wise, it is the next best thing. I know it is an iphone-clone along with S2U2, but they both do what I want for this particulalar purpose, so who cares!
Maybe one of the things they have fixed is where non HTC (4-pole connector) headphones make the phone act oddly like randomly redialling the last number dialled and the volume rocker fast forwarding tracks instead of doing the volume...?
Breaks Bluetooth Audio
Hello all.
I installed this hotfix on to Artemis 8.0 ROM and it broke the streaming of music to my bluetooth headset. Tried re-pairing the headset etc. to no avail. Anyone know a quick fix to return the audio output to my BT headset?
Thanks...
Guys, it says for HTC Sense. But thoes this effect WMP at all? I never use Sense to play music. But I have seen that WMP just randomly stop playing my music etc.
Any idea?
This fix does nothing for me... i still get lag, the pauses every 20-30 seconds...
REALLY ANNOYING. Although it didnt do it before, it jsut started in the last couple days, after a hard reset. ????
Does anyone have a solid solution to this problem? i dont wanna have to go to the 3rd party program EVERY time i want to listen to music.

I have now stopped using S2U2 and S2P and now using CHT Lockscreen and HTC Music again. There is still the Audio Booster problem, but with SRS WOW and Audio Booster on "Normal" it seems to be fine. I think if you choose a setting that it different, or customised then you notice the cut out. Either way, the phone seems more stable using less third party tweaks and software.

Audio issues (stuttering and granulation, artefacts)

I'd just like to see if anyone else is getting any audio issues, as I've noticed a few small things that marr the otherwise excellent audio quality that I get while listening to music:
- On bootup, the startup.wav sound often stutters, or is finely granulated.
- While navigating through menus, sometimes the audio stutters/is granulated. If I'm right, it correlates to the cpu clock speed being ramped up due to coming out of "sleep" mode. This is just speculation of course.
- Whenever audio is played, there is a very quiet but audible (with a reasonable set of headphones) click, followed by a quieter "hiss" which then plays throughout the audio being played, and for a short while after.
Now this last "symptom" I've heard on many audio devices, some much worse than others, with a rare few having no noticeable noise whatsoever. The Dell Streak I owned for a short time had a relatively loud and distinctive "click & hiss" combo - it was one of the reasons I changed to a Galaxy S. It just surprises me that a device where many people are praising it's audio playback qualities (for me) has some issues.
Anyways, I'd like to hear some thoughts on this, and maybe some people who have no issues whatsoever, with quality headphones, could show me that my particular device needs replacing - or that it is common to all devices.
I get the stuttering on start up everytime, I was also listening to some audio last night with headphones and there was lag and stuttering, I didnt hear any hiss but it was not a smooth process expecially switching between apps with music player running, it froze up for a few minutes.
I also tried going through the music player menus and not everytime but sometimes it would stutter just going into settings, at times this phone frustrates me more than my G1, but with the G1 i expected that, especially running eclair roms.
RUNNING JG5
I'm partly hoping that maybe FroYo, with it's cpu usage benefits, might help with the stuttering.
I'll also try to do a decent recording of what I mean later on tonight - Im at work with a laptop at the moment, so the recording quality is dire. I have no idea what I'm doing in terms of impedances/loads either - it means nothing to me
e: I've had a look in the other threads regarding audio - the one about the default EQ is interesting it must be said, but there are no direct implications for the issues I'm hearing here.
I should post my software version as well, though the problem has been endemic to the phone rather than the currently flashed rom - I currently use JM2, overlaid with SamSet pretties, Mimo's kernel and LauncherPro.
2 phones here with a hiss/whistle artifacts during the talk :-/
I recorded a vdieo the other day & the audio was totally trashed - all I got was gargling crackle. It was bad enough that I thought I'd got water in the speaker aperture! But playing music is fine (to my ears, anyway).

Definitive fix for the Galaxy S mp3 skipping/pausing/glitching problem

Hello all,
Coming from an iphone 3gs, I've had a wonderful experience with the Galaxy S, thanks in large part to the XDA community - Supercurio in particular.
His EQ fix for eclair elevated the Galaxy S audio quality over the iphone 3gs (IMO) which i used as my main music player, and with Froyo the EQ problem was resolved completely.
However, for me, and for a few users as well, a very nasty bug persisted - mp3 files would skip and jitter every 2-3 minutes in every song, and this for an audiophile was unacceptable - and frustrating to the point where i had stopped using the Galaxy S as my main portable player.
Having tried a number of solutions (eliminating widgets, shifting songs to external sd, using a task-killer, bashing my head agaisnt the desk etc), only one worked to put the problem to a permanent end:
http://androidforums.com/captivate-...-playback-stock-player-samsung-captivate.html
pr0virus: "Its from the CPU throttling during playback.
I had the same problem until I noticed while looking at a system panel app that while music was playing my processor would down-clock to 200 sometimes as low as 100mhz.
Got setCPU, set the minimum it would throttle up to 400mhz, kept it on conservative and haven't had a problem. "
So there you have it - Root phone, Install setCPU, set minimum processor speed to 400 (200 works as good in my case) and voila, you have the best PMP on the market!
Also, remove weather and toggle widget as that causes the skipping too
Many thanks again to everyone involved!
I haven't really thought about this problem for awhile. I recently started using my Galaxy S as my primary music player, be it mp3, m4a or flac. The problem is that it always seems to have some issue with a song during playback (aka: a glitch). It is infrequent, but very annoying. My S9 never has an issue, nor did my Clix2. Regardless of file type, and maybe not often, but it happens.
Initial experience with Froyo (xfjp7) was good. Last night it reappeared during playback of an album. Last song and all of a sudden that brief but distracting "glitch."
Will definitely give your advice a try. Thanks,
El Mono
I have this issue with my phone as well, but not consistently.
It goes a step further, though. Half the time it starts skipping, a second later the phone will actually turn itself off. The only way to get it to turn back on is to hold the power button for a long 10 seconds.
Anyone else seen this?
Think the setCPU fix will resolve for me as well?
I've experienced this kind of glitch or lag maybe twice or three times at all with my phone, and it was because i was listening to music, using maps, youtube and internet. I put my songs on external sd card, which seems to be better. And i also use voodoo lagfix (i don't know if it changes something, but my audioplayer became much better).
Hope it helps someone!
Cheers!
@omersak i have been suffering with this problem intermittently, and it was really getting to me and ruining my morning run! after searching i realised it was wrong to blame poweramp or supercurio! i did exactly as you said, but set for 'On Demand' and 200mhz minimum. have not had A SINGLE glitch since!
excellent work! thanks so much, i highly recommend this to anyone with music glitches!
Use poweramp, u can change the buffer settings and audio is fantastic!

[Q] Music apt-X falters, stammers or studders

So I have this Note 3 which I like a lot. Big screen to watch series in the train, although after a while I got pretty fed up with the chord of the earphones, expecially when I had to get up, swiched to music and had to stuff my phone in some pocket.
So I looked around for some nice Bluetooth headphones and came across a nice deal on the Sennheiser MM 550-X. Just stating the model for any chance that someone is aware of some faults in this product.
Now, overall the sound quality is fine, which you would expect because of the apt-X thing which both devices support. But what really annoys me, is the following.
While listening to the native musicplayer, the music sort of studders. Not all the time, but like one or a few times per minute and then not at all for a few minutes. Some faults sound like pops, but some are real pauses for like half a second. Especially with those longer pauses I can distinctly hear that the music really 'pauses' and that it is not just the connection which fails while the music on my Note plays on.
So I suppose it has something to do with the apt-X coding. I already tried rebooting, killing background processes, switching off wifi and mobile data. I also tried different music players. Nothing seems to help.
The only time when I have almost no problems is when I'm at home, with te phone lying still on the desk.
I have a stock rom.
Does anyone have an idea how I can fix this?

That's difficult, because I don't have a phone which supports apt-X available.

Most phones these days support it.
Maybe a friend's?
Maybe the problem is something else entirely. You need to troubleshoot it.
I am just guessing, though. Never used bluetooth headsets myself.
