Bug Report: Probable Cause of Stuttering in iTunes v7.0.2.16 -- Crossfade

Has anyone ever tried to send a bug report into Apple? I've looked all over and can't find anything that would let me send in a bug report.
I think I have tracked down one of the issues with stuttering in iTunes v7.0.2.16 Its in the crossfading in the play back options. If I disable crossfading, gone is the stuttering and cpu hogging at the start of a track. The length of the stuttering, how far it goes into the next track, is the length of the crossfade. Also, has anybody else noticed that with the stuttering comes a maxing out of the CPU? While typing this my computer will go unresponsive when iTunes starts a new track and stutters and I can watch the CPU Usage History spike during the attempted crossfade.
I hope that Apple finds this and it is a help in fixing the issue as I really do like iTunes. And if anyone knows how to send this on to Apple as a proper bug report, just post a comment letting me know and I will do it.
And lastly, any comments showing the reproduction of this evidence would probably be helpful to Apple in resolving this issue.

Okay Chris...
I've double and triple checked all of the bullet points in your troublshooter document, and all is in good order.
I found that my Direct X was out of date, and got excited when I upgraded it and started playing tunes. For about 5 or six tracks, there was not any skipping during the crossfade, but alas, the problem is still there, and still garbles the tunes at the very end and release of the crossfade.
Not ALL tunes, just a certain intermitant few.
FYI, this bug was never an issue until v7.0 was released. Crossfading in previous versions was not a problem, until now. So there must have been something that has changed, from the previous to this release, and my assumption is the gapless playback. Just a guess, as it is new.
Any other thoughts as to the cause? And beter yet... the solution?
I sincerely would like to keep using iTunes as my default music player...

  • Bug Report - uninstalling causing reboot

    Environment:
    WinXP, 32bit
    VMWare Player 6.0.1
    Network PPPOE
    When upgrading to 6.0.4, I have to uninstall 6.0.1.
    But during the uninstall process, my network PPPOE disconnect and then reboot.
    Workaround:
    Disconnect the PPPOE, then uninstall VMWare Player.
    I don't know if other VMWare products face this, neither if v6.0.4 faces this.
    Does anyone know where can I submit a bug?

    Can confirm.
    Installed A03 today and now I get duplicate keypresses every now and then, it's mildly annoying. I haven't tried rolling back to a previous BIOS.

  • Is there a place to submit bug reports for iTunes 11?

    I was wondering if anyone knows of any communities, or ways in which we can submit errors, or bug reports for the new version of iTunes, version 11.0? The 2 issues so far that I am seeing, is:
    1. My account information: iTunes shows I have hidden purchases, when on all my iDevices, I have 0. (In fact, before the update, I un-hid all previously hidden purchases, and it showed correctly).
    2. When syncing a device, on the last tab for items on device, on my iPhone 4, iOS 6.0.1, it shows I have 2 songs downloaded from my collection, when I know I have 0. (Verified by checking Settings>General>About>Songs = 0

    Yes,
    In iTunes;
    Help (pulldown)
    "Provide iTunes Feedback"
    However, as of this writing iTunes 11 isn't listed in the 'Version list, so make sure that you state the version in your description.

  • Stop 0x0000001e (0xffffffffc0000005, 0xfffff8800a07d7f0 - Windows Server 2008r2 SP1 patch level March 2014 - WinDbg probably caused by mrxsmb10.sys

    we run several Windows Server 2008r2 SP1 Enterprise as VM on two Stratus Avance xenserver based VM hosts. On both hosts we run a VM as file-server, RDS server including a little bit of DFS traffic. the underling physical machines are Intel based S5520UR
    with plenty full of needed resources, running since 2012 more or less without problems.
    Recently we on both physical hosts the STOP error 0x0000001e (0xffffffffc0000005, 0xfffff8800a07d7f0, 0x0000000000000000, 0x0000000000000000).
    This has happended now twice and we have no clue or idea why the Stop error arrives now were the VM is running for month without such an error.
    We have tried to analyze the problem with WnDbg and the result reported: Probably caused by : mrxsmb10.sys ( mrxsmb10!MRxSmbDeferredCreate+18a )
    We have searched for a solution and have identified some hotfixes which could be related to our problem
    Hotfix http://support.microsoft.com/kb/2521220/en-us
    and / or
    Hotfix http://support.microsoft.com/kb/2764302/en-us
    The latter one matches the typical use of the VMs in question, file-server function and a flat file based database system with corresponding file I/O. (However, no dramatic system load and approx. 20 concurrent users on the system.)
    The file NTFS.sys in the folder System32 are with a newer date and version as the version from the hotfix and we are not sure if this would be a good idea to replace it with the hotfix version.
    As we are a small cap company we could not test the outcome of such a change of essential OS files and we tend to stay away from this approach. On the other hand we have a high pressure to solve this issue as we have to rely on the function of this core
    system.
    WinDbg points us towards mrxsmb10.sys as a possible root cause, but my believe is limited and we have not the knowledge to understand the output of the memory dump file. (mrxsmb was over the last 15 years always a difficult “thing”!)
    Would someone so kind to point us to some useful steps or direct us to any helpful advise?
    Thank you!

  • Bug Report - Some items in your iTunes Library ... because the file could not be found.

    10.6 and this is still this is a problem?!?!?!?!
    Not like this is an obscure issue only affecting a few noobs. Google returns 11,200 results on this issue!t'
    Can we PLEASE at least allow the list of broken files to be dumped as a text file so I can find them manually! guess not,
    I'll just have to get out a pencil and write down 100 songs to spend my saturday looking up and fixing. Or I could let my wife purchase 100 songs she already has whenever this comes up...
    What's really infurating is that non-technical wife thinks this means she must go to the iTunes store and buy them again.  Is it just coincidence that this only happens to songs that we ripped from the CD with iTunes? Hmmmm?....
    what follows is for the programmers, please make sure this get's to the development group.
    iTunes is the only music library manager, Media player was not even activated.
    iTunes is configured to "Keep folder organized", "Copy files to folder when adding"
    this has been a recurring issue since iTunes 9.x for us
    The issue is persisted accross system and library rebuilds.
    some of the same songs recurr but most of the time the list differs.
    Library survived transfer to new computer and back for a system rebuild (new hdd) w/o this issue.
    I'm guessing 100 songs is an arbitrary limit for error reporting.
    Songs seem to get lost for the following reasons.
    Track number added to filename
    Spelling of some tags like Album, Artist, Title differ in iTunes library and the file path !!!!
    Only seems to happen to mp3 files.
    My suspicion is that iTunes is downloading meta data from the store and updating the mp3 tags and iTunes Music Library.xml then predicting the new file location without actually moving the file to that new location. I've enabled insert/update auditing on the NTFS folder to see if that provided any new info.  I'm also capturing iTunes Music Library.xml so I can compare it to the new one WHEN this happens again and see if there is a pattern there.
    Would love a bug number and feedback chanel on this.

    The missing file thing happens when files are no longer where iTunes expects to find them. Possible causes are that you or some third party tool has moved, renamed or deleted the files, or that the drive they live on has had a change of drive letter. It is also possible that iTunes has changed from expecting the files to be in the pre-iTunes 9 layout to post-iTunes 9 layout, or vice-versa, and so is looking in slightly the wrong place.
    Select a track with an exclamation mark, use Ctrl-I to get info, then cancel when asked to try to locate the track. Look on the summary tab for the location that iTunes thinks the file should be. Now take a look around your hard drive(s). Hopefully you can locate the track in question. If a section of your library has simply been moved, or a drive letter has changed, it should be possible to reverse the actions.
    Alternatively, as long as you can find a location holding the missing files in a relatively sensible structure, then you should be able to use my FindTracks script to reconnect them to iTunes .
    Although you say you haven't used Media Player it can be raised as a background process by visiting enabled web sites. Possibly worth you reviewing this post: Getting iTunes & Windows Media Player to play nicely

    Unlike Windows Media player iTunes doesn't have a feature to automatically update tag data, although it will sometimes spot when a 3rd party program has (say during playback) and then update its own copy of the data. The iTunes (Music) Library xml file is provided for querying by third party software and is rewritten every time there is a change to the library, but is otherwise of no relevance to iTunes. The library is maintained in the iTunes Library.itl file. I suppose what could be happening is that iTunes issues a command to the file system to move a file based upon its tag, updates its knowledge of where the file is supposed to be, but the OS fails to move the file for some reason. Alternatively everything could go as planned, but iTunes could fail to get the updated copy of the library written out to disk so next time you start you get the previously stored locations.
    I have ideas of my own about the best way to organise my media, but I'm quite familiar with the way iTunes does it. It might be interesting to see the details of one of the broken tracks, the path iTunes thinks it is at, and the actual path, in case there is anything that can be deduced.
    Apple don't run an open bug tracking system so you won't be able to follow reports/progress based on a bug number. You can drop a line to iTunes Feedback or get a free Apple Developer account and submit a bug report report there.

    One other possibility is having sufficient rights, especially if you are invoking it via some other app, rather than manually as a logged in user. If you are not logged in and instead invoke it via a web site action, I believe you will have problems reading the registry, accessing a desktop, writing to disk, etc.
    Sorry I can't be more definitive, but perhaps it will help.
    Please post your conclusion, if you find it.

  • Bug report: Energy Manager causes slow performance...

    Very slow Windows Startup..
    Energy Manager's plans and the problem occured using any plan as I remember, and it wasn't an issue with the maximum processor state. I had heavy disk usage, especially access to the Page File, which is what the person in the second link I posted also described. CPU usage was low. The disk usage was seemingly not related to Energy Manager (Chrome was usually the worst), but removing Energy Manager completely resolved the problem. If you would find it helpful. I'm quite confident that even with Maximum Processor state at %100, CPU usage was low when it was slow, and that disk access was the culprit.
    previously have use 1.0.0.31 or 32 not sure.
    Windows 8.1
    Im using Lenovo Energy Management Driver
    1.0.0.28
    4.6.2014

    I actually have the same problem.  Sorry to work on a old thread, but...
    I've got my Lenovo B50-70 less than 1 month ago, and had switched it to SSD and had set everything up and is working perfectly.  However there are a bunch of lenovo programs that came pre-installed.  This computer is used mainly for work and I really don't like programs that suddenly pop-up and ask you to do stuff, as it is quite distracting, and with Lenovo Energy Manager being one of them so I removed it.  (I did do some research before I remove...)
    Everything was fine, until when I try to switch on my wifi (I usually have it off, as I use LAN most of the time)...  For the B50-70 there is a airplane button on F7, which allow the user to switch wifi and bluetooth on/off.  That button was unresponsive...  After some digging it is actually related to the power energy manager being removed.  So I've downloaded the latest version from Lenovo and it was working again...
    However though, whenever I start my computer it is taking so long to start...  And I tried uninstalling the power energy manager and it solved the problem...  And I am stuck with either having no wifi on/off ability or a really slow boot, which loses the whole purpose of the SSD.  After you enter your username and password it originally takes around 5~10 seconds to login, now it takes over 1 minute.
    I have found this other link, which says Lenovo Power Manager having the same problem.
    https://forums.lenovo.com/t5/ThinkVantage-Technologies/Bug-report-Power-Manager-causes-slow-performa...
    There is a solution, which you can change the registry to switch a function off.  I've tried it and it didn't work, which is not surprising as it's a different program..  But I am hoping that Lenovo can provide a similar solution for Lenovo Energy Manager...

  • ITunes for Windows 7.0.1.8 bug report

    Do Apple employees actually read these forums? Is there some other (e.g. better) way for me to submit substantive iTunes bug reports to them?
    I've noticed a bug in iTunes for Windows, spanning both versions 6 and 7. I'm currently using 7.0.1.8 and the bug still manifests there. My iPod is a 60GB photo model, firmware version 1.2.1 (which is the latest available). This bug is reproducible on multiple PCs (by ripping the same CDs to two different iTunes installations on two different PCs), so it is definitely not a misconfiguration
    issue or a fouled up OS install or faulty PC hardware.
    If a song's artist field contains an ampersand character, then when the song is uploaded to the iPod, that artist entry does not appear at all in the "Artists" menu on the iPod itself. I have this problem with songs by "Korn & The Dust Brothers" and by "Larry Graham & Graham Central Station". Due to this bug, it's not possible to locate these songs by artist using the iPod's UI, even though the songs are indeed present on the iPod and can be accessed by album title.
    This bug is extremely obnoxious and needs to be fixed ASAP. Thanks.

    Chalk this one up to "bad feature design".
    Apparently the songs I was having trouble with just happened to be flagged (in "Get Info") as belonging to a compilation, and my iPod was set to "Compilations: On".
    I've never used the Compilations feature and I didn't understand how it worked. Apparently, any song that belongs to a compilation won't show up under the "Artists" view but will instead show up only under the "Compilations" view on the iPod (if "Compilations: On" is set in the iPod's UI).
    The Compilations feature isn't designed or explained very clearly anywhere, so I'm sure I'm not the only person who has been confused by its behavior. Especially since I never manually turned the feature on or manually set any songs I ripped as belonging to any compilations. I hope Apple will do something in future iTunes releases to alleviate that confusion.

  • ITunes desperately needs bug reporting tools

    Since this is the closest I'm going to get, I'd like to say that for some reason, if iTunes is minimized, whenever I use my media keys for volume (V up/down or mute), it gets counted twice. Works fine if iTunes is closed or focused, but otherwise, it doesn't. I also only noticed this behavior in iTunes 7.1.1. Why do all of their .1 releases break the control interface? 7.0.1 didn't let external programs control iTunes. Stupid people.

    hi Lance!
    actually we've also got (at long last) a dedicated itunes application feedback form now. it has a "bug report" feedback category. here's a link through to that:

  • Bug Report (reproducible) - Adding an appointment to Google Calendar causes Pre to display a blank calendar.

    I have been able to reproduce an important bug on the Pre (webOS 1.0.2).  I didn't see a way to submit an official bug report, so I'm posting it here.
    Step 1: Import the following ical file into a Google calendar:  http://www.halfwayproductions.com/test.ics
    Step 2: Sync the Google calendar to your Pre
    Step 3: Your Pre calendar appears completely blank!
    It's worth noting that this file doesn't import correctly into Google calendar.  Google gets the repeat wrong and puts the appointment at the wrong time.  However, this shouldn't cause the Pre to display a blank calendar!

    I confirmed that a meeting location with an apostrophe causes the event to not sync to Google Calendar. Interesting enough, I created an event on Google Calendar with an apostrophe in the location and it sync'd to my Pre, without causing the calendar to go blank. BTW, I'm on 1.1.0.
    This seems like it would be a very common occurance as many meetings or appointments could possibly contain apostrophes in the location (Joe's office, Dr's office, Arthur's Tavern, etc). It leaves me with little confidence of what is on the Pre and what is in my Google Calendar, as there could be other issues causing events not to sync, and they are obviously not "in sync." Is anyone looking into a fix for this? (Is Palm or Google listening?) In the mean time, is there any way to get a log of events that did not sync, as opposed to blindly assuming everything was uploaded fine?

    Some of these are known occurrences and I believe have been logged into the Palm SW database. Symbols had also been causing Facebook contacts to not sync properly as well. I don't know if getting a log of events that do not sync is possible at this time. However, if a user could post characters and their entry points that are known anomalies that cause the errors, that'd be useful.

  • Bug Report - Windows 8.0 - 6.0.1 USB arbitration causes USB keyboard driver failure

    Can't find a place to submit a bug report. So here goes.
    Full Error Message:
    Windows cannot load the device driver for this hardware because a previous instance of the device driver is still in memory.
    Problem Occurs:
    Windows 8.0 x64
    Vmware Player 6.0.1 build-1379776
    Problem:
    A USB keyboard ceases to function on the host operating system following the first host OS reboot after installing 6.0.1 on Windows 8.0. This issue does not occur with 6.0.0. The issue disappears upon uninstalling Player 6.0.1. Reinstallation allows Player to operate as expected, but issue re-appears after host OS reboot.
    The issue happens immediately after host OS loads, and continues irrespective of whether VMWare Player is launched.
    Looking at the keyboard drivers, the usb keyboard's driver has not loaded (see attached images). The built-in keyboard driver however reports no errors and continues to operate as usual.
    Changing the USB keyboard device to that of a different manufacturer does not resolve the issue. Any USB keyboard driver appears to fail.
    Work Around:
    1) Launch msconfig
    2) Disable VMWare USB arbitration service
    3) Reboot
    4) USB Keyboard works. VMWare Player continues to operate as normal, minus the ability to mount USB storage devices on the guest OS.

    This issue was fixed on my PC as follows.
    1) Taking ownership of the above usb*.sys files in  the drivers folder
    2) renaming them to usb*.sysold
    3) Using Device Manager to uninstall all USB devices with the yellow warning ! next to them
    4) Doing a Scan for Hardware changes via the Device Manager toolbar and then waiting a few moments whilst the USB devices are re-installed with signed drivers.
    Hope this helps you....

  • Bug report: ube_ipa: internal error when compiling with -xO5

    When compiling imlib2-1.1.2, one source file causes compilation to fail with the following error message:
    ube_ipa: internal error
    cc: ube_ipa failed for loader_tiff.c
    The command which fails is (probably wrapped):
    cc -DHAVE_CONFIG_H -I. -I. -I.. -I. -I.. -I../src -I../loaders -I../libltdl -I/usr/X11R6/include -I/usr/openwin/include -I/opt/csw/include -I/opt/csw/include -I/opt/csw/include -g -fast -xarch=386 -xstrconst -v -xildoff -xO5 -c loader_tiff.c -KPIC -DPIC -o .libs/loader_tiff.o
    Changing -xO5 to -xO4 works around the problem. The source file in question is imlib2-1.1.2/loaders/loader_tiff.c
    Patch 112756-10 has been applied, and doesn't correct the problem. GCC doesn't have any problem compiling the file.
    A quick note to any Sun employees reading this: it took me 45 minutes to find somewhere to submit this bug report. Searching sun.com for "submit bug report" turned up many forum postings where people asked "Where do I submit bug reports?", a bug report form for Sun One Java Studio, and not much else. It might be in your interest to make submitting bugs easier.

    Internal errors, such as the one you encountered, are generally considered compiler bugs. They indicate that the compiler reached an unexpected state and therefore bailed out. I opened bug 20703141: internal error: pic_relocs(): hh reltype? to investigate. I see the same error message emitted by the current Studio development release; I will update this thread if I find a work-around.
    Thanks,
    Mark
