For the lazy reader:
Your HD2 probably suffers from an audio lag using the default media players. This is evident in the transformers movies and many other videos. You just may not have noticed it for a variety of reasons. There is no fix yet.
Coreplayer/TCPMP are not solutions, since they defeat the purpose of proper HW scaling and decoding for battery life/processor utilization. They also render the video improperly (bad scaling, colorspaces, etc), and Coreplayer doesn't even support AAC+ (HE-AAC) audio.
BACKSTORY
The first day I got my HD2 from TMOUS, I noticed that the included Transformers videos suffered from what appeared to be close to a 250ms audio delay. Sure enough, the problem was universal to all video files unless an artificial delay is introduced into the transcoding process. This means that every video file placed on the device will play back with the audio playing up to 250ms (about 1/4 second) late. This turned out to be a very common problem with the HTC HD2 and many devices seem to suffer from it (including some other HTC devices mentioned in this thread), particularly in video playback. This is a not a placebo effect and is very noticeable--in some videos/scenes more than others due to video pacing.
Before you post to say "Mine doesn't seem to do it," read the following and check again just in case--you'll be surprised. As I mention below, to some people with untrained eyes, even a 250ms delay (about 1/4 second) isn't very noticeable, and without careful attention, the mind can sometimes be tricked into thinking the delay somehow "isn't real." The proof? Testimony of many members (read this thread), and of course: Here's a video of me playing the new test clip below.
This problem is well known and is often referred to as a "video sync" or "lip sync" problem. All seem to describe this problem in which the audio ends up getting significantly delayed.
STATUS
A list summarizing the current understanding of the situation.
1. The audio lag is up to 250ms (100-250ms) for ANY a/v stream. Please understand that the duration of 250ms is 1/4 of a single second; in some slow scenes (or even slow speech), this problem is very difficult to detect. However, in any very fast scenes or speech, it should become strikingly and painfully apparent to even the most callous of observers.
2. It does appear that a minority of HD2 users insist they are completely unaffected by the problem, and they are very vocal about it. This does introduce the possibility that, in fact, contrary to all common sense, there may be differences in HD2 hardware that are quite elusive. Alternatively, there is some yet-undiscovered combination of settings, roms, and drivers in which this problem disappears. More likely in many cases is the possibility that the issue is simply difficult to spot in some people's chosen sample footage.
3. HTC has acknowledged the problem in some form but is doing nothing about it, either because of development cost (software issue) or hardware issues. Again, there is also the possibility that there are other factors tying the company's hands.
4. In theoretical terms, the class 2 SD card read speed is more than sufficient to maintain sustained data flow of, for instance, a 300kbps audio/video stream. However, the delay issue persists even with the smallest of encodes, and even when the files are placed in the phone's built-in memory.
5. The Snapdragon chipset itself has been repeatedly implicated as being the culprit behind the A/V delay. Other potential candidates include driver issues, ROM issues, and/or general software issues on the part of HTC.
6. It is absolutely not a codec issue. This is not speculation or conjecture, but certainty. There is an overwhelming amount of evidence to support this, including the use of different players and encoders that produce valid streams--which play back perfectly in sync on any other computer or device. If there is any software you are using that you claim "doesn't get lag," you either do not experience lag/delay issues on your device, or the software is introducing opposite audio delay to compensate, which isn't a solution at all. The latter is known to occur with some community-produced frontends specifically for the HD2 as a crude workaround for this issue. However, it is hardly necessary to stress that the dilemma of not only re-encoding every existing media file for the HD2, but also the obvious lunacy of producing invalid files specifically so this device can read them.
7. The issue is ROM-independent. Cooked and stocked ROMs produce identical results. However, some users report a slight decrease in delay when they disable processor scaling (i.e. lock the device near 1ghz).
WHAT YOU CAN DO
First, decisively determine whether or not your device has this problem, which a large number of HD2 units seem to have. To test this, play this video (or others mentioned in this thread) on your HD2 in Windows Media Player or the HTC Video Player. Also try the included Transformers movie if you have a TMOUS unit. If you have any other media players on the device, you may also play these clips in those players with default settings. Note that all of these files are properly encoded and exhibit no audio lag when played using a computer or other device (including the original HTC HD). Report your findings, along with your OS version, ROM version, radio version, and model of HD2 (i.e. TMOUS or "European"). Also indicate your purchase date or, if known, the date of manufacture.
Secondly, once you've confirmed you have the issue, contact HTC and issue a report/complaint (in other words, request that they fix the problem). To support your complaint, you may refer to some of the ticket numbers at the bottom of this post, which are relevant to this issue. Once your complaint is filed, post the complaint ticket number here. It is crucial that HTC understands the prevalence of this problem or they will not fix it.
Finally, propose a solution (optional). If you manage to change device settings or install software/drivers/tweaks to eliminate the issue device-wide without destroying the file's actual synchronization (i.e. it remains in sync on the computer, other devices, etc), please post what you did! Please, no touting random 3rd party "converters" unless you understand the approach used by these to escape this sync/lag issue.

Another test video. This was the default test clip until I replaced it with my own above.
Sorry, George, its not everybody's doesn't do it. Seriously, no matter what you may think of my mind, etc. mine doesn't seem to do it.
I'm not trying to say the problem is non-existent, you might be right. I didn't investigate enough.
But to give my 2 cents; I am very familiar with video encoding, digital audio and video and everything related. On a PC or on a TV i have an eagles eye (ear) for spotting sync problems. But I haven't noticed a sync problem on my HD2 whatsoever after having watched several movies on it... and 250ms should be very, VERY noticeable. Just 20ms usually catches my attention right away.

I'm also very familiar with encoding. I also notice stuttering problems in the video I play, in addition to sync issues (even baseline AVC with 1 ref, bitrate capped at 1000kbps, LC-AAC audio at 64kbps). This problem was even present on the included Transformers movies (the same movies play fine on the PC-- but with the exact same sync issue on coreplayer and TCPMP on the HD2).
Do you have the TMOUS device? What radio and ROM version are you using?
One other interesting thing I noticed. When the volume is turned down to 0, the choppiness present in some videos or situations dissappears, and when the audio is turned back up the choppiness comes back (tried in HTC Media Player).
This might relate directly to the sync issues I'm experiencing. What if there's a problem with the audio module or chipset rendering in general?
Change your thread title. its misleading. just because your device and someones friends first cousin sisters ex boyfriend suffer from this delay doesnt mean that ALL HD2s are affected. and to claim that all apps are affected? do you have all apps that are out there? kind of farfetched to say its a widespread occurence when this is the first time anyone has claimed such a "MAJOR FLAW!!!"

Changed; happy yet? And I'm not so sure it's as "misleading" as you think. I've seen more with the issues than without. If it occurs on all the included videos and apps, I think it's safe enough to say it's a problem with all of them.
If you don't think your device has it, feel free to post to the contrary. It would help to specify what version of the device you're using.
Based on the responses I'm getting, the problem seems constrained to the new 1024 Leo units (the TMOUS devices). If you have such a device and don't have this problem, I (and many others here who complain about the sync--it's not just me) would love to know about it.
A little less arrogance, please.
no audio issues here either... TMOUS stock using CorePlayer in GDI
To OP
I have TMOUS hd2 with stock rom, since I read this thread, I watched Transformers couple times using built-in player and Core player, but I did not notice any audio lag.
You said 250ms audio lag, what programs you used to measure this number, how you measure audio lag in game? Karaoke game?
Thanks
The lag is measured qualitatively; I adjust the skew until I find that there is no more lip sync issues on the video files (basically I change the delay until the audio matches exactly with what's being shown). Then I observe that this audio delay is the same in all videos (including the stock). Then I notice that games are a bit delayed; since the 250ms appears to hold for all of the videos I've tried (the audio delay was set by an mp4 container flag), I simply assumed that the lag that is observable in games is the same; it appears to be the same magnitude, at least.
I noticed it in the Transformer movie as well. (This is probably the first time I played it and paid attention.)
TCPMP can't handle the Transformers movies. I can't notice any lag while playing another video file I had on my sd card. The quality is much lower, compared to Transformers.

TCPMP solved my problems (Audio sync in videos, I don't have any delay at all in apps etc though).

TCPMP runs 2.5 - 3 hour action films fine for me.
I've experienced no audio sync issues in the couple included games I've played with (all but Prince of Persia) nor any in the videos I've played (both Transformers and a couple other mp4's I've encoded with CloneDVDMobile). I'm not a big fan of games on these though, but the video capabilities have been THOROUGHLY tested on my unit. Oh, and all of this has been played from the supplied 16GB card and two 8GB cards (both made by Kingston) which I already had. I've played the videos using both the included "Video Player" and TCPMP (took a little work to get MPEG2s to play decently though).

I'm turning it off now, now that I'm thinking on it).
To those of you experiencing these issues: Are you only seeing this problem with games? Or is it affecting movies too?

I did not say that TCPMP couldn't handle long films. It was very specific to the Transformer movies. More specifically, I meant the exact Transformer movie files that came with the US T-Mobile HD2. TCPMP was not able to play those Transformer movie files smoothly.
However I do notice the audio lag in the default movie player it uses to the Transformers movies. The video is smooth, but the audio is lagged a little.
I am experiencing the exact delay that is being reported.
All you have to do is actually watch a few minutes of Transformers. Its really annoying.

No you just said "The Transformers movies", I have 2 transformer movies & TCPMP plays them both fine. They did not come with the handset like yours though, but they are both high quality of 2.5gb each (Don't know how big the issued ones are, I'm in UK here so we didn't get them).
So maybe it's an issue with the way they were encoded too as well as a hardware issue.
i don't have such an issue with mine... games and movies play fine... maybe you have slower ear sensors or faster vision lol .... and I am curious why do you advertise this in your signature?????? if you were writing in a sports forum and had some disability, would you write that down in your signature as well??
i have this same problem. I loaded my favorite alert sounds from my previous phone. They all get a half second to a second chopped off. So do my ring tones. I have not seen a fix for this on any board yet. You are not crazy.

It's not actually the first time, there was a thread running for a few days not so long ago about the same issue. And as far as I can ascertain, most, if not all HD2's are plagued with this issue.
I have a TmoUS HD2 and I haven't noticed any delay in sound.
Hi guys. I got myself a 32gb, wifi only version of N7. Upgraded it instantly to 4.2.2 . Nothing to complain about in the first 2 days.
After that, I noticed that, when I play music (stream through upnp on local network or play mp3 / flac files on local storage - tested several players, bsplayer, google player, poweramp...), and do some other stuff on the tablet at the same time - surf, or just 'click around', or swipe through my documents - occassionally I experience short sound dropouts, like the I/O-load would be too high or something. Please note this isn't bluetooth thing some people experienced, I use regular phones. It happens sometimes when I do some trivial stuff...noticed it all over the place, while starting an app, surfing, writing something in the Google search window, searching people on FB, opening a browser (empty) tab, even clicking on application button to see the list. It can be really anything, it doesn't happen a lot but it's there.
I googled the problem but couldn't find anyone with similar issues. Read on the other hand a lot about general performance issues of the Nexus 7 after 4.2.2 upgrade, about (visual) lag, so I figured, even though my eye didn't catch that on my device (this is my first experience with 4.x.x so it looked fast and smooth enough to me), I decided to revert to 4.1.2 and see whether there would be any difference. I can't say I could see/hear improvement, maybe a slight one, but I still get to experience occassional chops in my music, which is very annoying, this should be ridiculously easy for a 4-core processor to accomplish. It's unacceptable. I even checked that CPU wasnt overloaded when these chops occured (in fact, it was only around 25%-30% when the chops occured, perhaps the peaks were too short for program to register them - I dunno)...
I also tried everything people suggested here regarding general performance issues, disabling this and that, Currents, factory resets, cleaning cache partition...you name it. Nada.
Anybody experienced similar thing? Don't know if I have faulty unit or if this is bug in software (Samsung Galaxy S3 had a similar thing when it got out, even though the sound pops were of different nature and occured under different circumstances - took several software upgrades until it got fixed)...I'm thinking of returning it and go for iPad mini or something.
Thanks in advance for any feedback.
The results of this have varied but there are some who attest that this works.
Have you disabled auto-sync in Google Currents (Blue Circle Icon)?
If not, try that; this has worked for me.
Open up "Google Currents" Hit the 3 dots on the top right -> Settings -> Scroll down and UNCHECK "Enable background sync"
Remember these results have varied, but it fixed the issue with my tablet. Also I heard there were some issues (although if someone can confirm them further for us--that'd be appreciated!) with the RAM in many Nexus 7s so stressing out the ram and filling up your SDcard to the max will cause it to have stutter issues too.
Hi and thanks for the suggestion,
Disabling the background sync in Google Currents was actually the first thing I did. I believe I tried out everything that was suggested so far on the net regarding the general performance issues. I used Forever Gone app to fill up all space and then delete it, I wiped the cache partition in bootloader mode, I even did a factory reset, and eventually I re-flashed it back to 4.1.2 (it did improve then but the music lag / pops were still not entirely gone). SD-card space-thing cannot be the issue either as I have like 23gigs free.
Now I even noticed that video playback is effected by occasional sound pops. When I play video in full screen, not doing anything else, it still happens. Rarely but it does happen.

Returned it and took money back. Will look for other options soon. This thing was too 'beta' for me.
wondered if anyone else suffered from this - not sure if its an "Android" or Note 3 issue
basically if watching streamed video - in particular Netflix and Youtube - I can't get smooth playback
the phone seems to drop frames (noticeable by either causing judder or a sudden slow down/speed up as it catches up)
this is via 3G or via Wifi - makes no difference
same content on IPAD is silky smooth
I've tried forcing 2D acceleration in dev settings to no avail
it seems like the hardware or OS can't keep up with the video at all times
local content plays back completely smoothly, be it podcasts via Pocketcasts or local video files via MX Player - perfectly smooth - even at 1080p
any ideas please ?

I noticed something interesting this week -although maybe Placebo (pretty sure not though)
I've always had laggy/stuttering Netflix vs smooth on IOS
yet smooth local 1080p content - perfect really
I was trying Sky Go earlier in week and was lovely and smooth in fact I'd noted how smooth the video playback seemed vs Netflix, tonight I noticed stutter on Sky Go was beginning to think if I was running something in background or something - but then figured the difference - tonight was streamed via Wifi, earlier in week was same/similar content but downloaded first
so is there something odd with chipset that it doesn't like Wifi + Video decoding at same time ?

MX Player (and others) might use hardware decoding, Netflix and the sorts might not.
You could go to Dev-settings and check on "Show CPU usage", so you can see whats happening. (But you'ld have to google what it all means as i dont know.
But what i do know is that the procces list shouldnt be too long, like 20 items in my list when idling (for 5 minutes) after usage.
Do you guys get video stuttering on Netflix? It's pretty bad on my tab 4 8.0 to the point of getting a headache. I've tried 2.4 & 5ghz but no change. Battery saver is off. This doesn't happen on any other android devices I own. Even my old tab 2 runs Netflix smoother. Any tips or is this how it is on all tab 4s?
Could someone try Netflix and let me know how it is on your tablet please.
Tested Netflix on my Tab4 8", no problems at all.
Do you experience this stuttering on any other video app?

Tab 7 here. I get a bit of stuttering but rebooted and plays smooth again.
Sent from my SM-T230NU using XDA Free mobile app
I've tried out some other players like mxplayer and also stuff like YouTube and video playback is smooth. It seems to be just Netflix that is having this issue for me. I've restarted and all that but no luck. Netflix is the only one getting this stuttering every few seconds. Real annoying. Not sure why. I've never seen Netflix act like this on any of my devices and other tablets that I currently own.
Try clearing the cache, try reinstalling?
i have the same problem
what i have tried so far:
1. re install firmware using Kies.
2. format cache, factory reset from recovery
3. clear cache, restart app
4. disabled screen mirror, smart stay, palm motion , switched to nova launcher...
5. limit background process, check do not keep activities.
6. disabled power saving.
7. disabled multiwindow.
edit: also tried
8. clear all other apps cache.
9. Turned off all the bloatware.
10. installed task killers, show no process running since they are Turned off.
11 disabled rotation
12. enabled airplane mode
I also noticed movies in SD does not shutter. only the ones in super HD.
don't know what else to try, and i don't want to root and lose warranty.
playing 1080p 60Hz videos shutter a little bit, I'm starting to think that is just that the CPU cant cope with doing many things at the same time like using wireless an decoding video. since day 1, i noticed that while the updates were downloading and installing it became very laggy over all, and I was like, what are 4 cores there for then? its just that its a crappy tablet and that's all.
I've tried a lot of the things above to and Netflix is still having this micro stuttering. I noticed that if I lower the Netflix quality in my settings it will still stutter so it has nothing to do with the tablet not being able to handle high quality. It almost seems like there's a bug on the Netflix side with this tablet that is causing this or something. It's kinda sad that my old tab 2 7.0 Netflix stream is better than this new tab 4. I also have a shield tablet that just blows both these away but that's expected. My wife and daughter use this tab 4 and they watch allot of Netflix on it so I would really like to figure this out. Anyone else have any ideas on what to do or know if there's a bug that needs to be ironed out with Netflix and this tablet. Maybe there's a update from Netflix or Samsung to fix this problem in the future...if they know about it.

Hey I just got my Z4. Upgraded from a Z2 Play. I bought direct from Motorola off their website. I'm having really strange 2D performance issues, and was wondering if anyone else is having similar issues because they seem outright stupid for a phone as beefy as this one is to be doing this.
OK, so, this is going to sound super vague because I did try to nail it down with a ctrace, but wasn't able to come up with anything conclusive.
Sometimes, when drawing 2D only, my phone will drop to 30fps or lower. This happens in both in the launcher/normal apps and games (Fire Emblem Heroes)
However, when the phone is drawing in 3D (Dragalia Lost) the phone never drops below 60fps, ever, for any reason.
I have tried the developer option to force 2D Drawing on the GPU. This does not change the behavior at all.
This happens regardless of what MotoMod I have attached (None, Car Dock, Projector, 360 Camera)
This seems really weird to me. The phone isn't getting hot. It happens both plugged in and unplugged. Fresh reboots and not. What's interesting about this is it's exactly the opposite of my Z2 Play, which Dragalia F***ing hated (It would run fine for anywhere from 5 to 30 minutes, and then it would crash) but FEH would run fine on, and never ever have issues, ever, even if the phone hadn't been rebooted in like, 3 months. And the Z2 Play is just generally a weaker, crappier device in every way (Except Ram, I had the 64gb/4gb model of the Z2 Play) than the Z4, I kind of "expect" the Z4 to just do everything the Z2 did but better.
I'm not a particularly heavy user (I upgraded from my Z2 Play because the battery was expanding, not because it was insufficient) and both of the games mentioned are the only things I do on my phone that could be considered to "Push" the phone in any way (Push in quotes because Dragalia and FEH are both REALLY light games.)
Has anyone else noticed any strangeness like this?
I have the same issue, and yes, it's really hard to describe and difficult to determine what causes it.
What it actually looks like to me is that the digitizer randomly goes into a powersaving mode and samples input at a lower frequency. When scrolling through any app, if you hold your finger down, it'll make it look like it's running at 30fps or less. But if you fling a page that can scroll, for the most part the scrolling animation will be full 60fps.
I know for certain that if you reboot the phone, you're more likely to trigger it soon after boot. But, if you suffer through the agonizing experience, the phone will eventually fix itself for the next week or so before it happens again.
Here's the weird part, not everyone is affected by the weird performance. My theory is most people can't detect it or don't care, or there's a particular app that is prompting the digitizer to behave badly. No idea what it is though.

Here's the weird part, not everyone is affected by the weird performance. My theory is most people can't detect it or don't care, or there's a particular app that is prompting the digitizer to behave badly. No idea what it is though.

It's definitely not the digitizer though! I have some data! Fire Emblem Heroes has an autobattle mode, This is as likely to happen during an autobattle when I am providing no input (Phone sitting on desk/just watching while holding) as it is when I'm scrolling through my list of apps.
Same problem here, pretty sluggish experience compared to my girlfriend's G7 Plus.
I've noticed that since the latest update, this issue has gone away for me. Anyone else confirm?
I don't think it was the update, but certain apps seem to exaggerate performance issues. I fixed mine by marking Pokemon Go (the only 3d game I play), as "Restricted" under battery usage settings.
I've been testing this configuration for about 2 days now and it looks like that solved it.
Just to set the record straight, the Android 10 update fixed the random performance problems that have plagued the device so far. There is some hitching right after a reboot, but if you let the phone settle, it's fine until the next reboot.
