    <p>I have developed an app that plays audio files with some voices recordings. When I debug it I have no problems with it, when I download it from the AppStore it works perfectly, my friends use it and they haven't got any problem with the app, but a few people from all over the world have contacted me to tell me that the app doesn't sound. </p> <p>It is very strange because they tell me that the sound of the bell (mp3 44100Hz, mono, 128kbps) that plays first sounds but the voices (mp3 44100Hz, stereo, 96kbps) don't sound. The people that contact with me has different devices models and different versions of iOS 6.</p> <p>I use AVAudioPlayer to play the files and I think that it work well. </p> <p>Have you experienced the same problem?</p> <p>Thank you </p> <p><strong>UPDATE</strong></p> <p>This is the Localizable.strings that I have</p> <p><img src="https://i.stack.imgur.com/jmRMZ.png" alt="enter image description here"></p> <p>I load the file like this: </p> <pre><code>// NSString *fileLang = NSLocalizedString(aItem.fileName, nil); //more code ... thePlayerURL = [[NSBundle mainBundle] URLForResource:fileLang withExtension:@"mp3"]; //more code ... AVAudioPlayer *player = [[AVAudioPlayer alloc] initWithContentsOfURL: aItem.urlAudio error:&amp;error]; player.delegate = self; [player prepareToPlay]; </code></pre> <p>This is an example of the Localizable.strings with the file keys and values, by default the name of the key is the spanish version of the file:</p> <pre><code>//AUDIO NAMES "1_au_es" = "1_au_en"; "2_au_es" = "2_au_en"; "3_au_es" = "3_au_en"; "4_au_es" = "4_au_en"; "5_au_es" = "5_au_en"; "6_au_es" = "6_au_en"; "7_au_es" = "7_au_en"; "8_au_es" = "8_au_en"; "9_au_es" = "9_au_en"; "10_au_es" = "10_au_en"; "11_au_es" = "11_au_en"; "12_au_es" = "12_au_en"; "13_au_es" = "13_au_en"; "14_au_es" = "14_au_en"; "15_au_es" = "15_au_en"; "16_au_es" = "16_au_en"; "17_au_es" = "17_au_en"; "18_au_es" = "18_au_en"; "19_au_es" = "19_au_en"; </code></pre>

    1. COhave you ensured that their vibrate button isn't flipped on? I wrote a translate app that had the users simply mute/put the vibrate button flipped on. It seems simple, but I've gotten almost 15 emails for that alone, no audio. lol

    2. CO`AVAudioPlayer` uses the device's volume settings while `AudioServicesCreateSystemSoundID` uses the system volume (eg. alert volume). Does the bell use the system sound API, while the rest uses `AVAudioPlayer`? They may have the sound muted or turned all the way down.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
