Glitches in MP3 Playback - Verizon HTC One (M8)

Hardware: Verizon HTC One M8, Gunmetal Gray, with a Sandisk Ultra 64GB microSDHC card (Class 10)
Modifications: Rooted, S-OFFed, TWRP 2.7.0.2 and ViperOne(M8) installed @ version 1.3.1, Firmware, Radios and hboot updated from Santod's uploads. Installed Viper4Android FX v2.3.3.0, using "High" quality driver. I've modified the EQ curve a bit, but made no other changes to effects. It's only enabled for headphones.
Problem: Occasional glitches when listening to MP3s via Google Music (and only experienced when using headphones so far). I'm not playing from the cloud; the MP3s are stored on the microSDHC card. Seems to occur every 20 minutes or so, within the first 10-30 seconds of the start of an MP3. It's not at the same point each time, and I can't repeat it on demand or I would assume it's a bad copy of the file. The glitch is a very brief but very noticeable gap/hesitation in the file that's playing, like it's rebuffering or something. It only lasts a tenth of a second or so, but that's plenty long enough to be noticed.
I'm tending to think it's a problem with Viper4Android; next step is to uninstall it and see if things improve. Not sure what I'm going to do for EQ without it, though.
If anyone has thoughts to share, they'll be appreciated.

I've been experiencing the same thing. I've tried several different audio players but there's little difference; there are skips in tracks played off external storage. I'm on stock rom, with faux kernel. I experienced this with a completely stock device. My gut feeling is that the issue lies in the sd card, I have been trying different i/o schedulers and read ahead cache values. Some combinations have helped slightly but not enough to eradicate the issue, it could even just be coincidental.
I'm going to go ahead and say it has nothing to do with the rom, and it shouldn't be a cpu issue like I've seen on other devices since the glitch occurs regardless if the phone is awake or not.

Same here, playing off the sd card it will skip

Wow, so I'm not alone. I'm surprised I didn't find more hits on this issue when I searched; perhaps my google-fu is weak.
I couldn't imagine it being hardware related; this thing is orders of magnitude more powerful than any of my old MP3 players. I guess I'll live on the bleeding edge with ROMs and new kernels to see if it clears up. Thanks for your feedback!

Happens on my stock rooted/s-off using Poweramp

I'm pretty sure it has to do with the CPU being used too much. I was messing around with different clock speeds and trying to see how low I could take it and still be usable, and the lower I got, the more and more glitches came up.
Also, it is not just for mp3's. I get the glitches on spotify too, so I'm assuming it has to do with the overall audio output process, not just the reading of music files.

I'm inclined to say it is not a cpu issue, as I haven't encountered any problems using music stored on the internal memory.

I've been giving this issue some thought, and did a little research (probably not enough to talk authoritatively, though ). I've come up with the following observations:
This issue appears to have surfaced with Kit Kat.
Wiith Kit Kat, Google made some significant changes to the handling of external/removable SD-cards; no more direct write access to them from applications.
A lot of media player applications were "broken" by KitKat and needed to be redesigned to support the new restrictions.
The standard protocol for moving files to the removable SD-card is now MTP.
Which raises the following questions, at least for me:
Does this mean that MTP is the protocol for accessing MP3/media files from player apps, and therefore there's now an arbitrator/server in between the filesystem and media players?
Now that direct write access to SD-cards has been restored via an edit to /system/etc/permissions/platform.xml, is there a chance that an older MP3 player may have better luck playing MP3 files, given that it would probably use direct filesystem access vs. going through MTP (if in fact MTP is used for "new" applications)?

So it's not just me? It doesn't happen as often for me after the ota

You're doing god's work, man. It would certainly make sense if mtp was the reason behind all of this, as mtp is generally broken and incapable of parallel tasks. Perhaps, then, there is some kind of operation that the OS is performing at fairly regular intervals that disrupt what should otherwise be a simple read. Media scanning? Entropy generation? I'm not really sure, but clearly there is something silly going on in the I/O. Maybe a programmer like @SSukk could shed light on this

I think part of the problem is the amount of storage on the larger cards, and/or the fact that they're just not fast enough . My 64g card is a ultra and has problems. I bought one of the faster extreme pros and have never had any problems even when fully loaded. It's only 16g though. When the larger cards get faster speeds well see this disappear entirely.

A microSDHC card doesn't have to be very fast to keep up with the demands of playing MP3s. MP3 players were using much slower flash memory 10+ years ago without glitches or skipping.

I think you're onto something. I'd love to get some input from someone who understands the nuts and bolts of media playback in Android.

I have Google Music playing from the cloud on occasion, but most of my playlists are cached to SD. I don't use anything to modify output other than leaving BoomSound on, and I've not run into this glitch with headphones or Bluetooth,

Bump!! Wanna see more answers to this question! Haven't put MP3s on my phone yet but already installed a 64 GB card for the intentions on doing so!

Had mine in airplane mode for a while this morning as I was traveling to NYC. If anything, the glitches seemed to occur more often. I don't think they were predictable enough to say with authority that airplane mode was related, though.

Just curious, how are everyone's cards formatted? My 64gb is fat32, apparently. I suspect this to be a problem, even though it wasn't on other devices. However, I'd like to see if we all have that in common before I reformat and have transfer 60 gigs of music back over...

I didn't format mine after installing it, and I'll bet it came formatted as ExFat. I'll see if I can find a way to verify and report back.

I used this to figure out how I was formatted: https://play.google.com/store/apps/details?id=com.sylkat.AParted

Mine's definitely ExFAT.
On a related note . . .
I was sitting in the Stage Door Diner at 33rd and 8th Ave this evening (no, that doesn't really have anything to do with this issue, but it injects a little bit of local color into the story . . . I live in Maine, but I love NYC ), browsing XDA on my M8 while stuffing my face. For no apparent reason that I could see, a toast popped up with "Preparing SD Card." Now, I wasn't doing anything specific that would be accessing the SD card; as I said, I was just doing a bit of web browsing. But I thought that toast normally displayed only when the phone was booted and/or plugged into a computer via USB (and nowadays, with MTP being the default transfer mechanism to the SD card, it normally isn't seen then). But it looks like some process was doing something that caused the SD card to be "prepared," whatever that means, and since my music is on it, I'm suspecting it might have an effect on playback if it occurs when listening to MP3s.
Has anyone else noticed this symptom during normal usage?

[Q] Apps on SDcard go missing? usually??

Is anyone running into a problem with apps that have been moved to sdcard just disappearing? Most of the time I see little green droid icons all over my launcher (ADW), and lots of missing apps in the app drawer. I can reboot several times and eventually all show up.
I'm running ee4_debloated-v421 / 0730_charge_voodoo kernel / sdcard_patch. Am on my second handset (first one had a clicky button go dead). The earlier handset occasionally did the same thing.
I presume the sdcard is the culprit, as it is the common element. But I have popped it out, run fdisk and defrag all with no errors.
Any theories??
I had this happen when I first got my charge. How I fixed it was I took the SDCard out of my phone and put it into my flash media reader, and then did a full format using HP's Format tool with default device settings. It took a long time to do the full format, but after doing so, I didn't have any more issues with apps disappearing that were installed to the SDCard.
Full format, huh... (gulp) well it's certainly worth a try! I'll report back.
Thanks,
Larry

I know when the phone first came out, there were several users with SDCard problems. I'm not sure how others fixed them, but a full format and a half hour or so fixed mine
Well, I'm disappointed to report that the problem did not disappear :-( Could it be the contents? I copied *everything* from the card before full formatting with the HP tool (which tooks hours as you said), then copied it all back. Same result... if I reboot enough times it will come up with all apps showing.
I've ordered a Class 10 card. Plan to use the HP tool on it straight away. What else would you recommend? Maybe move all the apps back to the phone? Would you start from a fresh load of the ROM?
Many thanks,
Larry

I know that DroidXcon over in the Android Central forums advises NOT to move apps over to the SDcard because of problems like you have experienced...the higher (class) speed card may help. I've noticed that on my stock class 2 card when I view a subdirectory that contains large wallpaper files using QuickPic or Gallery, the thumbnails will often "time out" and not display towards the end of the list unless I refresh the listing several times. I would assume it is for the same reason that recording video to the class 2 card will time out after a few minutes.
Good luck with the Class 10 card...keep us posted!!!
Well, the Class 10 arrived in time to try again, so formatted with HP Utility and copied all the saved files over. Same behavior.
If it's the sheer quantity of apps on the SD card and there is a timeout involved, that might explain it! Reformatting the card would effectively defrag it which would speed it up, perhaps explaining imnuts' observation. And if reading in all those apps at startup is not I/O bound but maybe CPU bound, that would explain my experience.
I'm going to try moving apps back to the phone just to see.
Wow, this is persistent. Moved all the apps from SD back to phone using TiB, which seemed to hang sometimes. Tried different access methods with no clear winner. Anyway, after a reboot, the situation was unchanged. Unreal.
So I am starting from scratch with a freshly-formatted Class10 card, a full data/cache wipe, and a new ROM: GummyChargedFE1.9.1. Haven't had a problem yet, but haven't restored anything to SD either. Proceeding cautiously.
Ok, I'm converted. GummyChargedFE1.9.1 solved this problem. Everything seems to run better. Added the V6 SuperCharger thing which tweaks minfree levels and much more, and the combination runs extremely well.
Biggest problem for me is that I'm satisfied... spent the last two years trying to get my "original" Droid to run well, then got the Charge, started over. What do I do for an encore?
Fast Boot option may be the culprit
In case anyone is following this old thread ...
I did not need to install a new ROM
CUT TO THE SOLUTION BELOW -- SEARCH FOR ////
Some (not all) of my apps moved to SD (all by Titanium Backup Pro) have begun to disappear and (sometimes) reappear without warning after I began to add and delete large Virtual Machines created in QEMU from my 16GB SanDisc class 10 microSD card on my HTC Droid Incredible running rooted stock Verizon Android Froyo 2.2.3. I know this thread is far from my phone's "home base", but from what I can tell this problem with disappearing apps located on an sdcard is NOT determined by hardware or even Android version.
I also happen to use LauncherPro by Federico Carnales instead of the built-in HTC Sense launcher. I noted elsewhere on XDA that a user had suggested that because at least some (maybe all) launchers start before the SD Card that this may be a problem, especially if changes are made to the sdcard that the launcher did not perform, or was not active during their performance by other apps such as Titanium Backup. That fits my situation, because I unmounted the SD, physically removed it to a PC, and added/deleted large VM files to save (lots) of time. No problems of this sort before I did this, so there must be some connection.
I noted that other users have tried reformatting SD, substituting different brands of SD, using newer/older SD etc. None of these reliably helped. So I skipped these options.
//// The (simple!) solution I tried that SEEMS to work (only time will tell!) is buried in the main Android Settings (accessed from the Menu button while in Home screen). Under "Applications" there is a setting "Fast Boot" that I checked long ago and forgot about (it seemed like a good thing to do at the time). The text warns "Turn off to use some Market apps" (that shows the age of my 2-yr old used phone and Android OS -- ohmygosh!-- because it refers to Market rather than Google Play Store!) Anyway, I unchecked the option and rebooted the phone.
Yes, it took a bit longer to boot (maybe a whole minute!), but after waiting about another minute ALL my home screen apps had normal icons and loaded properly. Titanium Backup Pro batch scenarios confirmed there were no apps in a forced uninstalled state (i.e. I had not done the deed, the system somehow had done it or at least rendered the apps "invisible" to Titanium, which decided they needed reinstallation).
The only odd behaviour was that auto brightness was turned off after I unchecked Fast Boot and rebooted. Going into Android Settings > Display and rechecking "auto brightness" took care of that. No other oddities or strange behaviours thus far (but it has only been about an hour).
I will report back here on this thread only (Samsung Fascinate > Fascinate Q&A > What just happend? apps on sdcard) if anything else requires reporting. Silence implies success!

[Q] ICS, Sd card, and usb radio, seems incompatible.

Hello.
just signed up, but have lurked and searched for a while.
I've recently updated my phone to the official ICS update.
And, i regret it. Loved it before, and should have gone with the old saying of "If it ain't broke, don't fix it.
Phone is not rooted, and is on TMOUS.
radio is a pioneer deh-p6000ub
sd card is Lexar MicroSDHC 32 GB Class 10
I have searched here, and on google trying to find an answer to my problem, but to no avail.
I thought I had found it in the noob question thread, but nope.
Problem: SD card is giving me a lot of issues when plugged into my car radio's usb. I'm going to be as detailed as possible, so may be a bit of a read.
when first plugging it in, the phone doesnt recognize that its plugged in, stereo gives me "N/A USB" plug an unplug a few times and it works.
**already solved this first minor issue, apparently the phone has to be unlocked to register that the usb is plugged in now. wasnt like this in GB, minor inconvenience, but not a big issue.
once i get it connected it will register, and start playing.
then, while playing, it will randomly go silent for a second, then continue. will play at least one song all the way through while periodically going silent, then start the next, and after about 20 to 40 seconds, will just jump to a random song, play about 30 seconds of it, and jump again, rinse, wash, repeat. annoying.
When going through the menu's on the radio, its very slow. it takes about 10 seconds to load each folder name(one folder per line, 3 lines show on the screen at a time.)
Some albums will play fine for the most part, maybe just a couple of silent moments (we'll call it skipping.)
some albums are unplayable.
While listening to the music on the headphone jack, it works fine. no issues at all. only issue is that after plugging it into the usb, the phone itself no longer has saved where i stopped playing music previously through the headphones. always did before.
Probably related is the issues with the gallery. after being plugged into the usb and then disconnected, the gallery takes forever to load and be useable. cant access pictures or videos on the sd card for at least 30min to an hour. can take new pics and view them with no problem, but cant see the old ones. i can go through root explorer and access the pics on the sd card that way, but not the galler.
I have no need for a custom rom, i dont do enough fun stuff bc i dont have time. and the majority of what i use my phone for right now is music. and i cant use it for that bc of the usb issue. stock rom does everything i need it to at the moment.
What i have tried:
different cables.
I put the sd card into an old motorola droid i had thats still on GB and tried it on the car radio and it worked perfectly. no issues.
i did a factory reset to the sensation
i cleared the media app cache
did a soft reset.
deleted and completely loaded a fresh copy of the album that has given the most issue, changed nothing (was hoping that maybe that particular file was corrupt)
took the sd card out and reformatted it (the suggestion on the noob thread for slow sd card issues.)
tonight, i hooked it up to a completely different usb radio (dont know what brand, etc, it was) and it gave the same issues.
one difference was that after playing a song all the way through, it disconnected from the usb. and the phone showed that it was connected charge only, not disk drive.
this card is extremely slow on this phone, and i cant figure out why. been searching for over a week now.
i beg of you, help me before i break it. lol. i hate singing along to my favorite tunes at the top of my lungs in my car, and then the song cut off and having to hear how awful i sound.

While I am not sure how to help you with your USB music issues, I can help you get back to ginger bread if you like once you have s-off on your phone you could simply flash the firmware and ruu of your choice to have a stock ginger bread sense rom but, before we try that have you tried to clear the data from the gallery apk to see if it makes a difference? Also do you have USB debugging enabled? It sounds like your rom is having issues with mounting the sdcard efficiently. Do you have any apps that maybe trying to access the sdcard while it is unmounted, thus causing an issue?

I would suggest a simple solution of ruu... It installs fresh copy if ics.. But at the cost of losing phone data... It won't touch the sdcard though...

just cleared the gallery cache. USB debugging is not enabled, I enabled it for a couple days and it didn't make any difference.
no apps installed that should have any effect on sd card. running on bare min right now, less crap I'll have to reload after continuously resetting and deleting.
will save going back to gb as the last resort. would really like to enjoy ics, just this one issue I'm having.

will prob try this soon, at least before reverting back to gb.
one more thing I forgot to put in the first post:
the sd card is not encrypted as far as I know. and the encrypted sd card option is not selected in the storage menu. not sure if this has any bearing on anything, just thought I'd post it up just in case.
Well at this point a ruu would be the vest man for the job. Do you need a link to one or do you have one? If you need what's your network?

http://shipped-roms.com/index.php?category=android&model=Pyramid OK here is a link to all the ruus I can find for the htc sensation. And here http://shipped-roms.com/download.ph...0U_11.23.3504.07_M2_release_256085_signed.zip
Is the most up to date tmobus ruu that I can see. Make a backup of everything you can like text messages, ect. Anything on your sdcard will be safe. Once you ha e done that plug your phone Into the PC/laptop and run the ruu. It will flash the phone with the stock tmobus ics rom. And hopefully fix your issues good luck
Usual disclaimers apply, if you phone explodes, starts a revolution, Marrys a dog or leaves you late for work its on your head what you flash onto your phone is your call.

[Q] Spotify on SD card

So I just got my Z3 and a 32gb sd card, and I would really like to have my music collection on my sd card. I found out how you do it but you need a hardware menu key for that.
Do you guys have any idea how I can store my offline tracks on my sd card?

First uninstall Spotify from your phone
Then before you reinstall it make your your 32GB card has more free space in it than the internal card. Spotify will automatically create it's offline storage folder on the SD Card with the most space at the time of installation.
That's it. Nothing more complicated than that and it will create this folder on the SD Card even on Kit Kat Android.
Even with a hardware menu key it still wouldn't be possible.
This phone hates SD cards altogether unfortunately. No option to transfer apps to sd card, no way to transfer things using 3rd party apps, and most annoyingly of all, you can't even transfer content to it over USB either, as either the file explorer crashes or Sony's own media go app crashes.
Simply put, the phone does not have permission to access the SD card for anything other than the built in apps, i.e. file explorer.
I had to use one of those sandisk usb to micro usb flash drives just to get my music on there. 2MB/s read/write speeds are NOT fun when it involves 20GB of data.

This is just plain incorrect information. See my post above.
I have Spotify, PocketCasts and tTorrent Pro all accessing and writing to my external SD Card on my unrooted Xperia Z3. Once the app being installed creates a folder on the SD Card then it can write to that folder.
Thank you G1032, it worked, I think.

Could be different for each region then I guess.
As for the stock unbranded UK one I have, it just doesn't allow it at all. Same was true for the previous 2 defective Z3s I've had. The whole thing is botched for me.

What was defective about them? My camera app has started freezing today and the the phone shut down and wouldn't boot up again unti lI plugged the charger in...(there was 73% battery left)
I'm thinking of returning it on Monday.

The first one had a very poor screen, the bottom half was very bright compared to the top, as if the panel was bent showing more backlight through at the bottom. It also had a broken wifi/bluetooth chip. Wifi signal was unobtainable on my AC router in a location where all my other devices had full reception. Bluetooth dropped out when I put it in my pocket or covered the back of the phone with my hand. On top of all that, the battery drain was ridiculous. On 20% brightness I was struggling to get through the day even with many features and sync disabled.
The replacement had a faulty camera button, so I didnt even bother to go any further with it. The screen was far better in colour and contrast though compared to the first, which was strange. No horrible backlight bleed at the bottom though.
The one I'm using now is almost perfect aside from the top speaker crackling/buzzing. There is small backlight bleed at the bottom, but it isn't bad enough to make the screen uneven like the first.
If the speaker becomes more of an issue, I think I'm just gonna return and stick it out with the Moto G till the Note 4 drops in price (should be about 400 quid by christmas).
Your camera issue sounds software related though. Similar to the SD issue I have probably.

I think you're probably right but I'm going to return it anyway. Should be no issue getting a new one. I'm not having a Z3 that freezes every time I take a photo or refuses to power on until plugged in!!

If it does it every photo then you certainly should get one. Sounds very annoying! Think I've seen a couple of people on here report similar issues.
Don't think I've seen a phone launch with so many different issues at once.

Buggy?

A little concerned so far. Won't recognize my ringtones. Won't run UC Browser. Some problems with SD cards.
Gonna give it a couple more days, but I've had phones that inspired more confidence.
And I do realize some challenges may come from running Marshmallow, not really being HTC's fault at all.
What do you mean by not recognizing your ringtones? And UC browser has a problem with Marshmallow, so it's not the phone. Can you elaborate 'some problems with SD cards'?
I mean I put notification and ringtone .ogg files on the phone and it will list them in some apps but not in others. But when I select one of my notification sounds even in the apps that show them on the list, the selected sound shown in the app is Firefly. The ringtone initially works if I can select it, even in the apps that display Firefly, but after a reboot they seem to stop working until reselected.
The phone's internet speed is very good, but very laggy/stutters when scrolling in browsers. Tried Chrome and Dolphin, both slower than my G2.
Still working out the SD issues. Phone says my SD card is slow. I do not have spec for this particular card, so I don't know if that's true. It's about a year old, so it's surely slower than the newest cards you can buy today.
The first card I tried got that slow warning but the class 10 Sandisk didn't and is working like a champ.

Note 20 ultra Disappearing video, unrecognizable file type.. and more crazy things. HELP!

So last week the tornadoes hit my hometown in Western Kentucky. If you watch TV, then you have seen it. 75% of the town is wiped out.. I have (should I say had) amazing video from that along with the destruction, the fear, there aren't really words for it all.. several friends are having issues with insurance and looting. I'm hoping some of their belongings are on my videos so police can prosecute the looters. (Totally not cool to steal from people who just lost everything.) Here's my dilemma
A couple days prior I changed My settings in my phone to record straight to sd card so I didn't have to move files to it. It's a SDHC. 1024GB MICRO SD. It was formatted because I've been using it for a while... just moving photos over to it from my gallery, no problem. Later that day I went to show the video and when I opened gallery I watched every video I had disappear and be replaced with the grey box and white exclamation. Photos I took are fine... eventually it has now greyed out 95% of my video.
I've tried playing on pc, with vlc, media player, Samsung video player, "unrecognizable file format " They are mp4. Here's what I noticed interesting.
I checked the SD card and it says healthy, no bad sectors.
The time length on each video says 0.00
The size of the file is different from the size shown in my explorer on my phone, pc, and what's shown by a file explorer/recovery program
I changed my settings back to record to the internal memory but still nothing.
I'm guessing headers or something didn't transfer or or hell who knows
I've changed the file extension and name. Nothing
I've tried converting but the file type isn't recognized.
Help! Here's photos of what I see
The last time I saw something like this, there was an issue with the card, not the phone. That doesn't necessarily mean that's your issue. But it's highly probably.
I agree it's the most likely scenario. Best thing to do is take a few similar test videos and replicate what you did on a new or different microsd card and see how it turns out. If it works and retains it then it's the original card. If not then it's an issue with the phone/ hardware itself.
I actually ended up copying the card and put it back in... the recordings I made next were fine! No settings were changed, and it's only the one Day they messed up... could it be because there was zero cell signal in town? Nothing could upload to the cloud.... I know moving files or even recording straight to sd will leave file pieces and signal most definitely should not affect storage on a device. I did get this data off one video though. Any ideas?
I've never heard of a data connection messing with storage of a device unless that device is separate and not directly connected. Again, doesn't mean it can't happen. But the most likely problem is still the card. You said you copied everything back on, what is happening to new content?
