You were getting help on this problem in your other thread. It usually is best to continue the active one rather than start an all new one for the same problem. If the answer(s) you get in the other thread don't help, specify why and the original poster, or others will usually add detail to their answers. Starting a new thread usually results in repeated work, as the respondents may not have seen what was proposed in the other thread.

  • When im listening to music and doing other things with iPad at the same time, the music stops and starts at random?

    Can't understand why my music cuts in and out?

    Have you tried restarting the iPad?  (Not just sleep, but hold the power button down until you get the slide to power off.)

    Try the standard fixes:
    - Rest. Nothing is lost
    Reset iPod touch:  Hold down the On/Off button and the Home button at the same time for at
    least ten seconds, until the Apple logo appears.
    - Restore from backup
    - Restore to factory defauslts/new iPod.

  • How may I automatically stop and start Mail services at a set time please

    Hi folks. I was wondering if anyone could tell me how to automatically stop and start Mail services (or any other services) at a set time please in Leopard Server? Is there a script someone has created which might help?
    Cheers, David ( a realy newbie when it comes to administering OS X server)

    launchd works through a series of XML documents that define tasks to run, either at launch, on a time schedule, in response to network events, etc.
    So you'll need to create two .plists - one to start the mail server and one to stop it. They should be saved in /Library/LaunchDaemons. I'd suggest something like:
    /Library/LaunchDaemons/local.postfix.stop.plist:
    <?xml version="1.0" encoding="UTF-8"?>
    <!DOCTYPE plist PUBLIC "-//Apple Computer//DTD PLIST 1.0//EN" "http://www.apple
    .com/DTDs/PropertyList-1.0.dtd">
    <plist version="1.0">
    <dict>
      <key>Label</key>
      <string>local.postfix.stop</string>
      <key>ProgramArguments</key>
      <array>
        <string>/usr/sbin/serveradmin</string>
        <string>stop</string>
        <string>mail</string>
      </array>
      <key>StartCalendarInterval</key>
      <dict>
        <key>Hour</key>
        <integer>1</integer>
        <key>Minute</key>
        <integer>00</integer>
      </dict>
    </dict>
    </plist>
    and /Library/LaunchDaemons/local.postfix.start.plist:
    <?xml version="1.0" encoding="UTF-8"?>
    <!DOCTYPE plist PUBLIC "-//Apple Computer//DTD PLIST 1.0//EN" "http://www.apple
    .com/DTDs/PropertyList-1.0.dtd">
    <plist version="1.0">
    <dict>
      <key>Label</key>
      <string>local.postfix.start</string>
      <key>ProgramArguments</key>
      <array>
        <string>/usr/sbin/serveradmin</string>
        <string>start</string>
        <string>mail</string>
      </array>
      <key>StartCalendarInterval</key>
      <dict>
        <key>Hour</key>
        <integer>4</integer>
        <key>Minute</key>
        <integer>00</integer>
      </dict>
    </dict>
    </plist>
    You'll need to either use launchctl load /Library/LaunchDaemons/local.postfix.stop (or start) to load the tasks, or reboot your server.
    I'm curious, though, as to why you want to do this. Mail is typically one of the services that people want to run 24/7 so they don't miss out on any emails (even though SMTP can tolerate this). Why do you want to shut yours down?

    Could be many things, we should start with this...
    "Try Disk Utility
    1. Insert the Mac OS X Install disc, then restart the computer while holding the C key.
    2. When your computer finishes starting up from the disc, choose Disk Utility from the Installer menu at top of the screen. (In Mac OS X 10.4 or later, you must select your language first.)
    *Important: Do not click Continue in the first screen of the Installer. If you do, you must restart from the disc again to access Disk Utility.*
    3. Click the First Aid tab.
    4. Select your Mac OS X volume.
    5. Click Repair Disk, (not Repair Permissions). Disk Utility checks and repairs the disk."

    Do you have current backups?
    Those symptoms could indicate a failing Hard drive. If it dies, all your documents go with it unless you have Backups.
    I have had very good luck with physical and battery problem diagnosis at the Genius Bar. Those guys put their hands (and their ears) to these machines, all day every day, and they know immediately what all those sounds mean.

  • Communication Channel Stop and Start

    Hello everyone,
    We are using XI along with MQ for queing messages to our 3rd party logistics. Due to some issues happened in the past, it is decided to stop and restart the MQ channels every weekend. Now the problem is, when the MQ is down, some of the XI communication channels will go down,  and will not start automatically, when the MQ bounces back. Now this had created a manual activity every weekend to stop and start all communication channels.
    Question is, is there any way we can schedule it as a job to stop and start the channels, at a specific time ?

    Hi!
    It is possible in scheduling the messages in XI...
    1.  But before doing this make sure that at what time you want to be schedule ?
    2.  Is that time will be uniform for every week or else is it may varies ?
    3.  If Uniform please make schedule or else if it is varying note the difference between those timings I mean
         If your Messages are flowing for every Tuesday and also every Thursday...., etc..
    4.  You can schedule what ever may be the time it is suppose if those timings are varying weekly once a
         day but in that single day or next day if it was more than once..then better scheduling the
          communication channels to be start for and to be process for that particular 2 days and remaining days
          it wont work I mean stopping Cc
    5. Now when come to process...in scheduling...
    a) Click RWB>Component Monitoring>Communication Channel monitoiing
    b) Right side u can check Availability TIme planning option click that..a seperate window will opens
        THere u can observe these options..
    c) also u can see the log
    I hope it will be useful to you...
    Availability plan--> ONCE /DIALY / WEEKLY/ MONTHLY based on your req select any one...
    Create: to create the scheduling...
    change: to change the existing one
    Save: to save
    Reset if u want toreset alll
    Delete and copy also as u know these..
    While creating you can again see these options 3 main TABS
    details:  --> Corresponding details
    CC: select ur chanel
    OPTION 2
    In XI 3.O you can directly do scheduling there after selecting the radio button of any Comunication channel and there adjacent to Audit log u can see availability time plan other than rt side top corder..
    I hope it will be useful to u

  • Cluster stop and start

    Hi Experts ,
    Is it possbile to stop and start the Sun cluster as like VCS (hastop and hastart).
    Regards,
    R.Rajesh Kannan.

    So many questions!
    It depends what you're trying to achieve. Sun Cluster is only started and stopped when you boot/shutdown Solaris.
    However, may be you actually only want to be able to make changes to a service without Sun Cluster trying to restart it, etc. If that is the case, then you simply need to disable the monitoring on the service in question and then you can do what you like with the service and Sun Cluster won't react.
    A typical example would be for HA-Oracle. If you don't stop the monitoring and then have the DBA try and shutdown the database, they will find that Sun Cluster detected the 'failure' and restarted the service. However, disabling the monitoring will allow the DBA to shutdown Oracle manually, make their changes and bring it back up again. The monitoring can then be re-enabled on the database.

  • Videos stopping and starting every three to five seconds

    I am having problems downloading videos from U Tube and msn. I can't even download videos from the Apple Site. The videos from U Tube stop and start every 3 to 5 seconds. They resume after 3 to 5 seconds. I have downloaded the latest version of QuickTime. I have gone into preferences-advanced and changed the transport setup to custom; set transport protocol to http and post to 80. I have also clicked on the streaming tab; set the speed to one lower than the ISP connection and move th enable instant on slider 2-3 bars from the left. What else can I try?

    There is currently no official version of MSN Messenger for Mac that supports video, unfortunately-- you might try aMSN instead, but I haven't used it myself so can't comment on the video support:

    However, the built-in camera works fine for me on Skype (and Yahoo last time I tried, which was a while ago), which suggests something else might be wrong somewhere...

  • Waveburner resets (64bit) IK Multimedia plugins when stopping and starting

    Does anyone else happen to have this problem:
    I'm finding that while mastering, I want to look back at the incremental changes made and have found that the Pultec EQ and some other plugins seem to default to a preset.
    In order to get to this problem I did the following:
    1 track in Waveburner, added the Pultec EQ,
    2 added a limiter chose a preset 'MIX PRESENCE' then got my desired sound.
    3 When listening everything seems fine and then you stop and start again, or go back to the beginning of the track by pressing the 'BACK ONE TRACK' button on the transport and all of the sudden the Pultec EQ resets to that original preset.
    So not too sure what to do, the only way of getting round this issue was to mix as best as I could, save as a new preset while it was playing and then when hitting start again then while it is playing then I quickly hit the preset on that I made and have to bounce my mix at the same time in order to finally get my desired output which is less than okay.
    Can anybody help. I'm running on an iMac, 64bit Version10.6.7 OS and Waveburner is 1.6.1
    Many thanks

    It is not just IK Multimedia and Waves plugs that are resetting on me; it is also the WaveBurner 'native' plug "Linear Phase EQ" and who knows how many others, were I to begin testing instead of trying to work through this.
    This little bug renders this software effectively useless for professional work.
    Some of my Waves plugs hold their values, others don't.
    Elysia products screwed up too; so much for that demo.
    As far as I can tell I am not using any automation, but, is there a way to globally turn off the possibility of automation (I tried RightClicking in the mix lane but there is no choice of automation available there, perhaps 'cause there is none as I suspect)?
    I am using WaveBurner 1.6.1.
    C'mon Apple, its November already; you must fix this.

  • APEX 4.2 aligning issue of Stop and Start Grid Layout item

    My APEX application application is in the process of moving from 4.0 to 4.2.  I am experiencing an issue with aligning (left margin justified) of Stop and Start Grid Layout items that have a border around them.  Earlier I had an issue with the border itself not showing up in the 4.2 application.  I was able to resolve that with a workaround by adding inline code in the CSS section of the page: #P23_OFFICE_START_TBL {width:682; border:1px solid #369; margin:5px;}. This created the border which I needed, but there are 2 Stop and Start Grid Layout items that are indented and not aligning with the border of the previous line.  I have tried a number of different things but none of them have worked.  This seems like a very simple issue to fix but I am having a tough time resolving it.
    I tried to put the item in question in a different grid, which corrected the indention but then I lost the border around the item.  It seems that the above CSS code does not work on the new grid.  I also tried to put attributes such as margin-left:5px; float: left; clear: left; float: left, in the CSS code but that did not work, too.
    Any suggestions?
    Thanks
    Ajay K

    I deleted and added back the Stop and Start Grid Layout items not aligning properly.  This worked.  Apparently, the 4.0 to 4.2 upgrade did not handle/convert these items properly.  Deleting and adding them back resolved the issue.

  • Burned DVD issues in DVD player not reading or music issues stop and start

    I'm a PC converted to a MAC (less than a month) and love it so far. I have been able to create and burn a DVD. The problem I'm having is one DVD player will not read the DVD (Hitachi). The other DVD player will play it, but the music stops and starts when it transitions (twirl) to another picture (Panasonic DVD/VHS combo). I'm using a DVD R Memorex. Neither one of the player are new. Would love to use this to make the Grandparent's a DVD of the grandchildren from birth to present as Christmas present. What do I need to use or do to be able to watch on any DVD player as well as the computers?
    Message was edited by: me01

    Hi me01
    Welcome to apple discussions. Try using 99 photos / less to avoid issues with audio fades / drops. Also do a search for Memorex on this forum and you'll see it's not the first choice of dvd's for most users. Instead try Verbatim, Maxell, or Taiyo Yuden and burn at 4x from a disc image for best results. Wish you luck and feel free to post back with results or any further questions.
