  • I have a new iPhone 5C, have the sounds alerts set up. But I'm not getting sound alerts for new voicemail, only the red circle on the screen.  How can I make the sound alert work?

    I have a new iPhone 5C, have the sounds alerts set up. But I'm not getting sound alerts for new voicemail, only the red circle on the screen.  How can I make the sound alert work?

    I have had this same problem for weeks now with my 4S.  I just got a new 5S after being extremely frustrated and the same thing - no sounds.  After searching posts all over, I couldn't find a solution. I just told my friend of the issue and he asked "Do you have the Do Not Distrub on?"  I didn't even know such a function existed.  Upon looking that was exactly the issue.
    To resolve, go to Settings> Do Not Disturb> Manual.  If it is green, turn it off.  You will now get phone calls and text alerts.
    This functionality is also on your quick access utility menu (slide up menu).  I assume this is how it was enabled on my phone.
    I will post on other sites since I searched for weeks for this solution and didn't see it anywhere.  Good luck!

Here is something interesting that i have noticed though. my main pc (which is the one i have always managed my itunes account with for years) is a 32 bit system running windows 7. Yesterday I installed itunes for the first time on my new netbook which is a 64 bit (windows 7) system and it works just fine. i have three other laptops (all window 7) in my household that are all 64 bit operating systems and ALL have updated to 10.5 and THEY ALL work fine. this is FOUR 64 bit systems ALL updated w/10.5 that work and ONE that is a 32 bit that will not. Can't get any help from apple. their suppot *****! I want to get someone on the **** phone or a live chat but cant. *** APPLE????? please let mw know if you find SOMETHING i can try next. I'm out of ideas and patience!

  • The maximum SOUND level is low on iPad mini retina, compared to an iPhone 4s. Research shows this is a common problem for this model around the world. Has anyone succeeded in solving this issue? Many Thanks, Peter.

  • Migration of balances for new ledger using the New GL

    Hi everyone,
    I have a specific scenario into this customer where we have implemented the SAP version ECC6.0 with the table FAGLFLEXT is active and using just one ledger (0L - standard). We need to create a new ledger for IFRS (e.g: 1L), as the customer didn´t use the splitting document functionality, it was not purchased the migration services.
    Now I need to upload the balances in the accounts into new ledger, I understand that for general accounts there is no problem because I can use the transaction FB01L and specifying the new ledger (1L).
    My doubt is : How can I to do the upload balances for open items into the AP and AR accounts?
    Anybody can help me?
    Thanks

  • As of yesterday 3/1/2015 T'bird stopped reading mail rationally on ONE of my two Windows 7 PC's and when aksed to check for new email retrieves the SAME message

    no matter how many times I ask T'bird to check for new mail I get back ANOTHER copy of the same message dated 7:28am and NO MAIL received after that reaches my INBOX. On my other PC running Windows 7 only ONE copy of the 7:28am transmission arrives as does all subsequent email sent to me at this address... both PC's are protected by Avast anti-virus software. Turning the rogue PC off and on did not help nor did uploading and installing an updated version of T'bird.

    Are the setup the same? same accounts, same folders, same messages, same filters same add-ons?
    If that the case make a copy of the good profile and replace the bad one with that.

  • Unable to create custom phone labels for new contacts since the upgrade

    I have a AT&T iphone 4 version 4.3.1 and since the last couple of recent upgrades I have been unable to create custom phone labels for any new contacts because the lower label options are gone. This is only a problem with new contacts. My existing contacts with custom labels are still there and if I edit those contacts the table that has create custom labels is also still there, but not for new contacts. Has anyone else noticed this problem.

    If you read the error above about the hash and manifest, you will se this is a RB Setup error and not a CM12 error. You would be better to post your question in the SQL forum or better yet to use BIDS instead.

  • DB Adapter: Polling For New Records returns the First record multiple Times

    I Polling for New or Chnaged Records against DB2 on iSeries. The DB Adapter returns the first record from the Table multiple Times. If the Table has 5 records it displays the first record 5 times. I am using BPEL 10.1.3.1 Can anyone help me with this.

    Hi there,
    please check out the DBAdapter trouble-shooting guide:
    http://download-east.oracle.com/docs/cd/B31017_01/integrate.1013/b28994/app_trblshoot.htm#CIHFEHFA
    I am copying an entry from there into here:
    A.1.21 Some Queried Rows Appear Twice or Not at All in the Query Result
    Problem
    When you execute a query, you may get the correct number of rows, but some rows appear multiple times and others do not appear at all.
    This behavior is typically because the primary key is configured incorrectly. If the database adapter reads two different rows that it thinks are the same (for example, the same primary key), then it writes both rows into the same instance and the first row's values are overwritten by the second row's values.
    Solution
    Open Application Sources > TopLink > TopLink Mappings. In the Structure window, double-click PHONES. On the first page, you should see Primary Keys. Make sure that the correct columns are selected to make a unique constraint.
    Save and then edit the database partner link.
    Click Next to the end, and then click Finish and Close.
    Open your toplink_mappings.xml file. For the PHONES descriptor, you should see something like this:
    <primary-key-fields>
    <field>PHONES.ID1</field>
    <field>PHONES.ID2</field>
    </primary-key-fields>
    Thanks

  • Remotely control your PC from ANYWHERE in the world using JAVA/RMI!

    I have just developed a project named XtremePC.
    This well commented Java project involved RMI technology, can be used to control the server from anywhere in the world including features of listing running processes, file transfer, shutdown/logoff/lock/restart server PC, execute programs, browsing in DOS/Linux fashion. The server is protected by encrypted password. I bet my time and energy on this project most for increase the strength instead of designing GUI. In response to huge request from AIUB, Bangladesh teachers and students for uploading my project of Object Oriented Programming-1 course, I have decided to come up with this Java RMI project with source code!! (Tested on jdk1.3, 1.4)
    Get it from the MyDownload section of my homepage: www.tanzim.tk

  • Is there a new version of the book "Beginning Java Web Services"?

    I am new to programming web services with Java. Is Beginning Java Web Services a recommended book for a beginner? Does it have a newer version as the one available was written in 2002. Can anyone suggest a latest beginners guide book?

    The MD387LL/A, MD388LL/A, and MD389LL/A are the latest models in the USA and Canada. It's the same in other countries, except for the LL.

  • General Trouble Shooting Tips for New Users

    Ok so we're starting a Topic to help out people just starting up with Logic Express.
    Me and a few others who frequent this board with a load of good answers thought it would be a good idea to offer a little helping hand to new users. Hopefully avoiding them their lapses in confidence and creativity by the way of limited techincal knowledge.
    As far as Professional sequencers and recorders go Logic is pretty straight forward and quite basic too. If you're coming from either using Garage Band 1/2 or maybe even a PC with Cubase, Cool Edit, Sonar or otherwise. You may find it baffeling to start with.
    So we hope this can be of some help to you.

    Crack open the champagne it's Tip 1.
    First off if you are using an external audio interface make sure it's plugged into your computer, it's powered up and drivers are installed. If using the internal sound card make sure all your connecting cables work ok and they are plugged in.
    If you're running Logic for the first time, it should recognise compatible audio interfaces when you run the initial setup. It should also set this to be the default interface from now on.
    If you've already been using Logic for a while and have just invested, then make sure and to to Preference/Audio and to the drivers panel. Select the driver there and leave all other settings as they are by default to avoid confusion.
    This should then allow you to record audio. SO go to the Edit/Arrangement window and make an Audio if there's not already one there. Then head over to the Mix window and find that channel (Audio 1 is normally all the way to the left). You'll see the faders and just above them the panners, above these will be two boxes the top is to set the input channel on your interface, and the second is the output.
    Set these according to the signal path you're trying to record hit the "Rec" button on that channel and you should either see the meter move up and down corresponding the sound, or you'll see the meter and hear the sound as well.
    You can turn off the software monitoring (ie being able to hear the sound coming in) in the same preference panel we looked at earlier. Under "Software Monitoring".
    Now you should be ready to record the sound. Switch back to the Edit/Arrange window and hit record in the transport bar. PERFORM. Hit stop. Go back to the start of the sound and hit play.
    NOW
    If you don't hear sound check the easiest things first. Is you audio interface or internal sound card connected to a set of speakers? Be it by means of an amplifier first or maybe you got some flash active ones!?
    Do the cable you're using to connect with actually work?
    Is the volume control up on the amp? Are the speakers plugged in?
    This may sound stupid but it's the most annoy thing to do wrong and it DOES happen.
    If this still doesn't work then double check all your drivers are there present and correct, the volume control in the computer is turned up, you have assign a valid output, and all levels within any software mixer that came with your interface are also all the way up.
    Still nothing? Post a detailed description of your setup and problem in the forum and someone will answer it probably within a day or so.
    Don't forget READ the manual, don't expect this to as easy as Garageband it's a different scale of operation which given time can reap massive rewards. Not always monitary mind you.
    Good luck.

    P.s. don't forget to rate posts you find helpful.

  • Looking for newer Mobo, like the MS-7345 Platinum P-35.

    Hello,
    I'm thinking about upgrading my P-35 MS-7345. I really like the MSI brand. I'm going on 5 years, but because of possible GPU issues (like screen ghosting, Non-responding, and timer continues to spin, even when I make a very simple video action, like adding a transition, everything freezes and hangs, to the point of rebooting. 
    Some people have asked if i updraded Win7 drivers for the MSI boardw hich i'm sure i did. Some asked me to check the board for bad or damaged caps, so I checked both the GPU, and Mobo, but could not see anything.  Then someone told me it could be the Power supply...really?
     In looking at Video cards, Like the PNY Quadro 600 ($150.00) requires a PCi-E 2.0x16, which I have now, but the higher end cards like the PNY Quadro 2000, ($400.00) and others, reqiuire a PCI-E 3.0x16.
    WISHY WASHY~  Don't know if i should wait to get a new mobo, before I buy a new card, becuz it's going to be a while. I don't want to buy the Q600 DDR3 now, to be obsolete and a non-performer compared to the Q2000 DDR5, which would be more faster, then I wonder, i7, more DDR3 memory, and a new Mobo, then use a slower DDR3?  Ummmmmm.
    To be honest, I like MSI, I bought my new MSI Platinum five years ago, and love it!  I'd like to keep it if i could, but technology supercedes practicallity, with the newer atx case with front USB 3.0 (mine is only 2.0....if it's backward compatible, then fine.) I'd like to ahead of the game, but not if i'm going to go BROKE!
     With my old build, with the mobo, Intel Quad Q6600,700W Toughpower PSU, memory,hard drives, That set me back about $1200.00.
    So..... for someone like me who is not a gamer, does not overclock, wants a minimum of 32GB DDR3, 700W PSU, three SATAII hard drives, does anyone have some Mainboard choices of newer LGA 1155 or 2011 that would either of these work?
    This time, I'll need the i7 (or i5) new mobo, new DDR3 memory...up to minimum 16GB, maybe 32GB, and that's that. I'll use what I can,. or give or sell this tower and everything inside to my sister.
    I was only looking at these two for specs:
    Z77A-G43 DDR3 1600  LGA 1155 ($ 97.00)  OR
    X79A-GD65 (8D) ATX DDR3 2400 ($ 291.00)   
    I know the MS-7345 Platinum is off the production, but is there a board out there that's similar to the MS-7345 P-35?  {it's just easy to set up.}

    If you already looked at X79A-GD65 (8D) and you are going for 16GB ram minimum or 32GB a Socket 2011 Core i7 would be a good choice. If you are just looking for an easy to setup system a X79A-GD45-8D would be of the same socket without any flaws but still somewhat less expensive.
