ios4 - iPhone SDK AVAudioPlayer - stop and then fail to start -

- 

- (ibaction)triggersound {     if (player == nil) {         nserror *error;         player = [[avaudioplayer alloc] initwithcontentsofurl:url error:&error];     } else if ([player isplaying]) {         [player stop];         player.currenttime = 0;     }      if (![player play]) {         nslog(@"fail");     } }

where player avaudioplayer , action linked uibutton. sound can played, , can played again after sound finish, when press button again during playback, message "fail" logged , sound cannot played, without exception.

i , using ipad ios 4.2.1.

i have noticed audio stream fails play after calling stop(which according reference undoes preparetoplay , play does). instead of calling stop, setting currenttime player.duration(end of stream) worked.
