Using CM7, having problems with Music Player

So the problem is, after I update the Network Widget Lite my Music Player starts to randomly skips music (like a scratched CD). I figured out that this new version was using too much CPU (like constantly 1%~2%) so I removed the program and the problem stops, but after a while it come back.
Tried to check my microSDHC using chkdisk and fsck.vfat without success (the FAT32 partition is aparently fine). So I don't know what to do. I am using Cyanogen Mod 7-RC1 and my microSDHC card is from my old Nokia XpressMusic 5800 (a 8GB One, original with Nokia logo).

Ok, so after I removed the data from Music Player and restored the original settings from ADW Launcher the problem minimized, but it's still anoying. Now it only happens when something spikes the CPU (like installing a new program from Android Market, opening a program, opening the main menu, etc). But this didn't happen before. Any clues?

Hi
I have the same problem when I unplug my headset(original HTC) the music player starts playing randomly and to stop it i have to kill the task. But the problem doesn't occur all the time it happens sometimes.
I think there is a bug in the event system, that restarts the player again and again.

[Q] App causes scrolling stutter

I have the Sprint HTC Arrive. Got it and the phone worked perfectly. Then after installing some apps, the home screen and apps menus would stutter when scrolling. So I hard reset the phone and it didn't go away. I went to Sprint and they agreed it was an issue so they replaced the phone.
With the new phone (which worked perfectly), I checked every menu after installing any new app. Everything was great until I installed POCKET RECORDER. As soon as I did that, the stutter came back. This time it's in my PEOPLE menu, pictures and web. Of course, I immediately uninstalled and hard reset. Well, the stutter is still there after that.
Anyone have any ideas on how to resolve or what it could be. It's a very annoying stutter. I am hoping I can resolve without an exchange again. Any help/comments would be appreciated.
Thanks.

I have the same problem,I own two HTC 7 PRO and one of them has the same problem - stutter when scrolling.
Either HR or Reflash do not help.

stuttering? how bad is it? and how are you scrolling?

i have an HTC HD7 and i do experience slight stutters when scrolling up and down the tiles(only noticed stutters when scrolling up and down the tiles). sometimes its scrolls smoothly and most of the time it stutters. i suspected as well that some apps make scrolling stutter yet im not that sure if there are apps that make scrolling a little laggy.
if compared with the page that shows all the apps, scrolling is much smoother than that of the start screen.
btw, i only have 24 tiles pinned on my start screen (just a run down of tiles. maybe somebody will be able to pinpoint which one is the culprit. i have settings, people, phone, messaging,xbox,zune,bible7, fs calculator, the weather channel, camera, me tile and 4 fave contacts tile, 2 email tiles, htc notes and notepad free, ie, marketplace, pictures and HTC hub)

Don't have any stutter and have pocket recorder installed. Never actually used the program though so just uninstalled as a precaution.

My guess is that this is due to the use of SD memory rather than NAND. The more you write to the SD the more you will notice "lag" when the OS has to re-read certain information.
Of course, this does not explain why it still lag's after a hard-reset, so I could be all wrong. I haven't come across it on my Omnia7 though, but did notice it on an early HD7 (this was part of why it went back to the store).

it's pretty noticeable. in some areas, it almost skips.

I dont have any of these programs installed. You may have to get it exchanged - that seems like the only fix.

BUT as soon as I loaded POCKET RECORDER, it started the stutter. My guess is the Pocket Recorder writes the the SD card in such a way that it causes some read issues. So even after an uninstall, the problem is still there.

Good plan. I would highly recommend not using that app! The stutter didn't happen until after I used the program once.

I have that problem on my HTC htd7. Makes sense if you have lotsof you sd card, but doesn't after a hard reset. I dunno do sd cards needs to be defrgmented? Could it be a hardware or software issue? Its starting to feel lke ms released wp7 way before it was ready.

Which phone do you have?

I have pocket recorder on my Omnia 7.
I'm pretty sure at some point in the past I have used the program.. I don't notice stuttering.
Any one else opened this program and not received lag / stuttering?

Let me address the stutter and NAND/SD Card issue.
The Lag in List Scrolling likely has absolutely nothing to do with the SD Card.
Lots of apps do not cache their data on the phone, so the issue is rarely from loading since the phone is downloading and loading that data into RAM, not to the storage. In some cases it may cache the data, but keep in mind that there are applications that actually store lots of data on the disk which do not lag when scrolling (horizontally or vertically). Stock apps do not display this, and most of them scroll (Calendar, for example, and I have a lot of stuff in mine) without any issues.
The issue I think is with the list control and how it functions.
Some people's phone may stutter, but the stuttering may be within their own personal "tolerance" limit so they don't think about it or notice. Some applications stutter a lot more than others, which leads me to believe it's a code issue.
NAND and SD Card are non-factor when an app downloads data from the internet to RAM and puts it in a list control to display on the screen. In many instances, the data those apps are loading into those lists aren't even touching the storage, nor is it even cached to storage.
Also, Windows Mobile Applications could be installed to SD Card, and even witih large lists most of those apps did not display this low level of performance... And that's running from a Class 2 SD Card on an HD2 (WM 6.5 Latest Stock ROM) with the entire application and all of its data cache installed to the SD Card.
If you can play Videos and Music off an SD Card, do you really think loading some data to display in a list control will make the phone lag? Really... Get serious about this, people...
The Storage Type is not the issue. The entire OS runs pretty good off of that SD card. There is something wrong with the list control, IMO... The Silverlight control, specifically (because I am starting to think Microsoft used more than enough Native Code in its stock applications).
A Web Browser with a large cache and caching almost every page you view scrolls flawlessly but a list in a twitter app that doesn't even cache data stutters? Seriously? It's the Storage Type's problem? Lol... No, it's not. And I've never seen any conclusive test to prove that (nor am I willing to perform my own, so take it with a grain of salt... it just makes absolutely no sense.. it's almost laughable...).
I've never experience any system-wide stuttering (I wonder if some of the SD cards are rubbish, in that case), but the list scrolling in WP7 is just unbearable. It causes ghosting and all kinds of effects on the screen that are neither bearable or ergonomic (leads to eye strain, headaches after prolonged use, etc. among other things).

I have to say I'm confused as to how an app could cause permanent problems to the phone. On a hard reset I think I am right in saying the internal storage will be completely wiped and re-written with the core OS data from the ROM?
And being ROM there is no way this can be affected without a flashing process... Unless you have some dodgy hardware/SD card and it is just a coincidence that this particular program was run when the problem appeared?

Bizarre behaviour when syncing large amounts of music

I had something bad happen to my rooted one x running leedroid 4 yesterday.
I sync'd a lot of music to the phone, around 15gb. I then disconnected it and went out in the car and the phone freaked out, everything crashed then it wouldnt boot for a good 10 mins, then when it did, it was really slow. The back of the phone was red hot.
anyway, i ended up having to restore from a nandroid. Everything was back to normal.
So, i decided to try again tonight. It did the same thing. This time i've narrowed it down to the music apps scanning the music. If I freeze out the apps (music & player pro) the phone works normally.
I've tested this a few times and get the same results. I've also noticed that when the music player is scanning (you can see the album list updating) the battery discharges faster than usb can power!!!.
During normal use, it's doing things like bluetooth streaming and gps at the same time with no issue. It just seems that writing to the internal "sd" is killing my phone.
Has anyone else transferred a huge number of tracks to this phone? Is this a rom issue?
It seems to work ok with lower numbers of tracks. which is leading me to believe that the scanning of music is the problem

This is an issue.
Had it too, sync the first 5gb, let it do its job. It will freeze, stuck, bug and **** as long as it is indexing the new music.

the irony is, my old desire v1 happily syncs and scans 16gb without a problem

Identical issue. I returned it lol
New one seems fine but I have left it stock. Its possible issue with my old one started after unlocking though it was present even after relock and RUU

[Q] Video glitch

Hopefully the powers that be don't do a DMCA takedown on my youtube video, but I've uploaded an example of a video playback glitch that regularly occurs on my device. Does anyone else see this on their Note 10.1 2014 edition? Very annoying... SM-P600, 32GB, USA version, MK1 firmware. Not rooted.
http://youtu.be/gU6x1CLGa8E

So far, I must be in the less than 1% that have experienced this problem...

you didn't include any info on the clip. audio codec, video codec, bitrate, profile, etc. what videomplayer are you using. is the glitch repeatable at that exact frame each time?

You can be sure that when somebody else had such problems, you will already find it here in the forum. So, no, never have such an issue. Also not over the network.
And, as mad squabbles already wrote: For more we need much more information.

The movie was downloaded from Samsung Hub to the device. HD quality. The videoplayer was the only one that plays these movies (to my knowledge): The stock Samsung video player. The glitch is not repeatable at exact locations. I can go back and rewatch the same clip and it will not appear, which says to me that there is not a data corruption problem. It seems like an I/O or "interrupt" problem to me. I've run Androbench on the device and I get as good as or better than the Anandtech benchmarks for the device.
This type of glitch occurs on any kind of move I play, including those I put on the device (mp4, etc). For the ones I have put on the device manually (not through Google Play or the Hub), I've tried the following players: Dice, MX, Archos, and the stock player.
In all other respects, the device works flawlessly: no lag to speak of (except for the occasional stutter on the notifications pull-down, which seems to be the norm). It doesn't crash randomly and battery life seems normal (no less than 7-10 hours of screen on time, ~4% drain overnight. The only thing that I have that probably isn't too common is that I do have MDM software installed (MaaS360) so that I can sync with my employers Exchange servers using TouchDown.

Normally I would expect that you have an background process which got more attention from Android then your video player. This can be anything. Did you have this issue also after a directly after a restart?

I just removed MaaS360 and rebooted. The glitch remains...

Factory resetting now. Will report back when I get it back online. I'll test video before installing any third party apps...

And.....it's still glitching after a factory reset.

First thing I noticed was that this scene is similar to super Mario live action movie
Second, this glitch can happen when you read from a slow SD card or can be reading and writing at same time, for example downloading from torrent or installing apps and playback movies from same location.

Indeed. However, movies are playing from the internal memory without any other significant activity going on. (no D/Ls, etc. just normal device behavior that is native to the OS) going on in the background. I also have played video in airplane mode...

and the media scan which have issues with scanning some files. Maybe you check which processes are running in the background?

There is always *some* process running in the background... I have cleared all other applications while playing a movie, but really, should this be necessary? (Problem still remains) I've tried playing movies without any non-stock apps installed. Problem occurs. I've tried freezing as much bloatware as possible without rooting before installing third part apps. Problem occurs.
What I would like to explicitly know is this: has anyone rented a movie from Google Play, played at least 30 minutes straight while doing nothing but watching the movie, and saw any stuttering whatsoever during that 30 minutes. I can live with it if it is a suboptimal experience due to firmware (I'm on MK1, btw) if this is "normal" for this device. I could only hope that it would be fixed in a future firmware update if that was the case. However, I have a strong feeling that if I sent this in to Samsung, they'll fiddle with it for 10 minutes, see that it "seems" to be fine (except for this glitch, the device performs completely as-expected for an Android device), then it be returned to me with no action taken. I can live without this thing for a few weeks, but it will be extremely annoying if nothing is actually done about it. Given that this glitch is not reproducible on command, I fear it will be an ongoing thorn in my proverbial behind. Unfortunately, my return window has expired or else it would go back in an instant.

Used Kies to download and reinstall the MK1 firmware in case one of the OTA updates were corrupted. No joy. Still stutters. Samsung Live Chat help of no use. I expect a call or email from them telling me to send it in in the next 3-5 business days unless someone else states that they have the same tablet and sees this problem too, possibly confirming that it is a firmware/device combination issue.

Mmm this is weird, I have no problem with video playback (any supported format by this device)
I have no MK1 but MJ2 and maybe media scanner is working hard in background

MX player shows glitches as well on movies that it can actually play. i.e., MX player doesn't play nicely with rented (digitally rights managed) movies from Google, which is the primary problem. Perhaps Android tablet users just don't rent movies all that much?

Media scanner isn't working hard in the background as far as I can tell. No to the two questions.

Issue with stock Music Player using available RAM!

Hey Folks,
I have an issue with the built-in stock Music player constantly taking all of the available RAM, which causes Android to start killing other processes like the launcher (Apex Pro), Tasker, nearby devices service (force closes occasionally), etc. It is very odd. I have tried several attempts to remedy the situation. I have, so far, cleared the Media Storage data, cleared the Cache partition from the boot recovery menu, have music on built-in storage and un-mounting my MicroSD card, to which none of these efforts helped. It seems like the Music Player app has a memory leak, which I am wondering if this was introduced in 4.3. I did not see it listed yet in the 4.3 issue threads, and not really sure if 4.3 is the culprit. I upgraded to the S4 from an S2 recently and a week later the official 4.3 upgrade was available. Thus, I do not know if this issue was happening in 4.2.2.
The interesting thing is that this leak or loop is occurring whether or not I have music on the device. So, to be clear, the issue specifically is when I launch the Music Player and then go to Task Manager to see the used RAM, the RAM will just continue to get used up until it reaches about 1.70GB or so out of 1.78GB available and then Android will start killing other processes to accommodate for more memory. This is when Apex and /or Tasker and other services start getting the ax. What's more, if I kill the Music Player (either right away or later), the memory continues to be consumed until it reaches about 1.5GB - 1.6GB and then finally releases and drops to 700MB - 900MB.
I am on a stock ROM, non-rooted and I have also confirmed this issue with my wife's S4 as well. We can use Google Play Music with no issues, but prefer the stock player if there is a solution to this "memory leak" or other situation that is causing the issue. If anyone has some insights as to what this issue is and a fix, please let me know. Also, if anyone can launch the Music Player and watch the RAM in Task Manager to confirm that this is or is not occurring on other S4s out there as perhaps it is an issue that some may not have noticed. In fact, my wife has been using her device in the car for a couple of weeks and streaming with Bluetooth and not noticed this was occurring. However, if she were to have music and use Maps/Navigation at the same time with this issue, Maps will get killed along with other multitasking tasks. I happened to noticed this behavior when I moved my music on the device and was playing around with the player, when I saw that Tasker restarted itself and then shortly after the nearby devices service forced closed and the music app got real sluggish. I then started observing the RAM usage with the launch of the player and realized why apps were closing. The funny part is that the music plays fine and never dies, it just kills everything else in its wake.
Any insight to this will be greatly appreciated. Also, I have been scouring the forums and Google in general to see if this has been mentioned and have not found this exact situation. However, if I did overlook a thread/post that has this as a known issue, please let me know what that link is. Thanks.

First off, damn. You might want to take a refresher course on how to say what you mean without all the extra words. You wrote a book man. 90% of what you typed is unnecessary. Nobody wants to read all of that and must won't even entertain a response. Just a friendly heads up.
Now, are you sure that the RAM is being taken up by the music app and not a combination of apps/processes? The stock task manager isn't very good for situations like this so you'll need to download a system monitor. There are quite a few out there, take your pick.
Could be that when you open the music player the media scanner is eating up RAM along with other processes. Those together are killing your memory. If that's the case you need to create a .nomedia file to place in the folders on your internal/external memory. Also, do you have any other music or media apps installed?
Figure out those then post back. You might try uninstalling all your apps then reinstall them one by one ( backup first). Yes, it can take a while if you have a lot but once you install the culprit - you'll know it. Hope that helps.

SOLVED!!
Ah, thanks for the heads up! Sorry about the long-winded post, I just wanted to convey the issue and what I have done so far. In future posts, I will be much more concise and to the point.
On a good note, I have solved my issue and found that if you disable/freeze/uninstall apps but still want to use the built-in music player, there is a conflict if you disable S Voice. I was going through the settings in the music player and noticed the voice control feature (which was unchecked), but clearly the player still wants to talk with or "see" S Voice out there. I took a shot in the dark and once I re-enabled S Voice, the gobbling of RAM from the music player launching stopped. Yay!!

Not solved!
Well that victory was short lived. That seemed to have only worked for about 10 minutes and it is back to the same memory gobbling issue when the player is launched. I reactivated Google Play Music and am using that with no issues, so it seems that will have to do.

Well that was all I had. I don't use the stock music player since I stream with Google Music.
You might look in the app store for an app to replace the stock one. Then uninstall the stock app so you don't have the issue anymore.
