ios - AVAudioPlayer does not audibly play, throws no errors, calls no delegate method -

-

encountering weird issue. i'm trying use avaudioplayer play simple sound file disk. maintain strong reference via property arc doesn't kill prematurely. said in title, no sound, errors , no delegate methods called--including didfinishplaying (which expect). thing seems "happen" hear 2 quiet clicks...

now weird part...if set breakpoint before [_player play], step over, audio plays fine!! confirms me have set things correctly, , makes me think else stepping on shared avaudiosession thread? i'm not sure. total lack of delegate calls odd--it seems something should called whenever avaudioplayer finishes.

i using openears speech recognition, call suspendlistening on before attempting play audio. have tried disabling openears entirely, try , isolate cause--but had no effect, either. perplexing. appreciate help!

-(void)playaudionotewithpath:(nsstring *)filepath {     nserror *error = nil;      avaudiosession *audiosession = [avaudiosession sharedinstance];     [audiosession setcategory:avaudiosessioncategoryplayandrecord                   withoptions:avaudiosessioncategoryoptionallowbluetooth                         error:&error];      if (error) {         dlog(@"error setting audio session category: %@", [error localizeddescription]);     }      nsurl *url = [nsurl urlwithstring:filepath];     if (!url) {         dlog(@"no file path!!");     }      _player = [[avaudioplayer alloc] initwithcontentsofurl:url                                                  error:&error];      if (error) {         dlog(@"error initializing audio player: %@", [error debugdescription]);     }      _player.delegate = self;      [_player preparetoplay];  // setting breakpoint here cause playback succeed.     if (![_player play]) {         dlog(@"error playing!!");     } }

well, seem have found fix, though i'm not sure why...since it's not code, moved calling class. calling class plays audionotes directly, instead of audionotes playing themselves. works.

-
i've been using 2 methods render data. the first one: function name($id,$name){ return '<div id="'.$id.'">'.$name.'</div>'; } echo implode($pdo->query("select id,name user")->fetchall(pdo::fetch_func,'name')); the second one: $users = $pdo->query("select id,name user")->fetchall(pdo::fetch_obj); foreach($users $user){ echo name($user->id,$user->name); } i don't understand how pdo::fetch_func works. tried figure out. however, not well-documented. could please explain fetch mode? , also, 1 performs better? thank you. both methods wrong , have learn how use templates , how separate business logic presentation logic. $users = $pdo->query("select id,name user")->fetchall(pdo::fetch_obj); tpl::assign('users', $users); is code business logic part. then in template <?php foreach $users $row): ?> <div id="<?=$...
