Stutters in audio playback every few minutes

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 ...

can you post rom version etc of your device?

I have the stuttering problem as well and it's really annoying.

I have the same problem - using windows media player playing mp3 files

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.

Youtube playback

Hi all, just want to check with you guys, is the youtube playback on your respective HD clear and smooth? Mine isn't clear at all with choppy playback. Even my friend's iphone has clearer playback compared to my HD. Is this normal?

Mine is choppy for the first part of whatever movie I'm watching, I think because it's still buffering in the background. After a while it's done and the video runs silky smooth.
By the way, I only watch YouTube over WiFi.

mine doesn't even after it has load finish, there's poor frame rate and is still slightly choppy. is it normal for it to have poor frame rate/choppiness cause when i view the same clip on my laptop, it's rather clear.

excellent response and framerate (over wifi) using the buit-in utube player but very poor using Coreplayer or other.. Could also be a router issue.

hmm..it has constantly poor frame rate playback no matter where i am, so i doubt it's a router issue. Am I the only one with this problem? It's kinda disheartening to see such poor playback on a HD device..

Mine has smooth, clear playback. I've only tested it using the HSDPA connection. A 17 MB video (4 minutes long) loaded and buffered really quickly (in max 8 seconds) and played smoothly and clear from start to finish.
It could be a problem with the connection, or with a lot of other applications running at the same time, or YouTube itself is sometimes buggy for a certain period of time (even on my desktop PC).
Try restarting or soft-reset your phone. Then connect to your PC via USB cable and activesync. Now view a youtube video. Does that change anything or is it still slow?

My experience with youtube both on wifi and 3g has been excellent I must say. there are some inconsistencies with how the files appear. most will appear FULL SCREEN, some appear as a square box in the middle of the screen (in landscape it's full height, just not the length of the screen). This may simply be something to do with the encoding of the video on youtube, not the connection of program. Just wish iplayer would work over 3 G now lol

Bug in Imagio Video Player O_O Any fix?

Thanx in advance for you time.
I just got my Imagio last weekend. I didn't flash it to any roms or anything yet, because I kind of like it like it is right now. The only thing is, I downloaded a movie in mp4 format and put it on my phone and here's what happens:
I play the movie. (It plays nicely.)
Something happens that I have to pause the movie. (Be it a call or knock at the door or what ever)
I come back to my phone and play the movie from where it left off.
But now, every 5 seconds almost exactly the navigation (Play, pause, stop, forward, etc) bar comes up as if I touched the screen.
It goes away and comes up again in 5 more seconds.
It does this through out the rest of the movie.
Any idea on how to stop this? (or maybe suggest a player I can download?)
I really didn't want to switch roms yet.
Thanks in advance to all da uba leet intel of the XDA Developers

try loading the video from file explorer and see if it does the same problem. that was my fix.

Results
Yes I tried it that way first then the other way (through the album tab) and still the same result.
It only does it if I ever pause it once. Then it (the navigation bar) comes up over and over all throughout the movie. =\
Thanx everyone for your time and answers. XD

Happens to me too. Hope someone comes up with a solution.

Same problem here. But when playing back video from the camera.. no problem.

what video framerate are your videos at. When my videos were at 25, this problem would happen.
when I set them to 15, it would be fine.
I am going to try a video at 24 and see if it still happens, will let you all know

This issue is just downright annoying. Has anyone come up with a solution as of yet?

I noticed it only happens with H-264 movies not with regular mp4 movies bitrate and framerate didnt really matter

any fix yet

any help
maybe a better wvga htc fullscreen player cab

any help updated roms have similar issues

Distortion in album media player.

I have noticed an unusual bug with the HTC Album video player and I am unsure what it is or how to fix it. It seems to only effect videos recorded with the HD2 (videos recorded with my old HTC Diamond play fine) however these same videos play with no problems using coreplayer.
At random points in the image frames there are elements of distortion sometimes these points turn green other times they are just blurry. These points like i say are random but in the same place and time frame each time an individual video is played (does that make sense? lol). I managed to capture some distortion with my mobiler. This is quite mild really, I have seen worse and I have seen this same video play with that bottom section completely green for half a second or so before settling correct again.
Any ideas guys? Anyone else having this problem?
Incidently this video is of my cat attacking the missus through the fence when she was gardening lol.

Slo-Mo video sometimes not working

Hi there!
Occasionally, when using the slow motion setting the video will record, play back in slow motion, but the fps will not be up to par - as in, it'll be set to 240 fps but will most definitely look choppier and not as smooth as I know it should be. A restart of the phone usually fixes this but there's no way to tell if it's not working until I record a video and play it back. Any one else experiencing this? Also, all the sample slo-mo videos online look so crisp and clear, while my videos tend to look pretty noisy, even with decent light. Any input is appreciated.

I've had issues when viewing the videos in Google Photos as well. Not sure if it's related to the video or other HDR photos still processing, or just Google Photos doing whatever it does to index them. I have sync set to charging only and wifi only, but when I was at my grandma's house taking videos of her dog jumping and doing tricks, when I played them back they would play OK the first time, but if I started moving the sliders and jumping to different spots in the video, it would freeze up or get really choppy.
Hoping it will be fixed with an app update soon.

I am having the exact same issue you described. It's not a playback issue. It's choppy even played back on a computer.
It is supposed to capture at 240 fps and stretch that out into a 30 fps video file. Look at the properties of a slow-mo video file, it should say something like 29 fps. When mine isn't working correctly, and the playback isn't smooth, that video file's properties says 7 fps. So, it seems like it's capturing 4 times slower than it's supposed to, at 60 fps or something.
Restarting my phone fixes it, for a few days. I've only had the phone a couple weeks and have had this happen twice now. No clue why this happens. Surely it's more widespread than just us.
As for the grainy noise, you have to have a lot of light, more than you'd need for a normal video. Mine are pretty grainy unless there's a ton of light.

Yeah, mine becomes choppy too sometimes. A reboot fixes it for a while. I've seen this issue posted a few different places so I think it's a software/firmware problem that Google will need to resolve.

Just wanted to add that I have the exact same problem, meaning that it still hasn't been fixed.

I know this is an old post, but I just got a 6p and I too have this issue. I'm even on DP4 so it's not fixed yet in this release either... Reboot is the only temporary fix I've found.
