Popping Sound

I made a simple app to play audio using custom audio engine.The audio engine supports audio format that encrypted like audio DRM and used a framework of Audio Unit.If the remote control in iPhone presses a playback button then must playing audio and changing playback icon to pause icon. So, my custom audio app had played, but the icon in remote controller was not changed.I think that may my custom app don't send an event notification to remote control. I want to send an event that my audio app is playing.I would like to get your good idea.rcc = [MPRemoteCommandCenter sharedCommandCenter];pauseCommand = [rcc pauseCommand];[pauseCommand setEnabled:YES];[pauseCommand addTarget:self action:@selector(playOrPauseEvent:)];playCommand = [rcc playCommand];[playCommand setEnabled:YES];[playCommand addTarget:self action:@selector(playOrPauseEvent:)];...- (MPRemoteCommandHandlerStatus) playOrPauseEvent: (MPRemoteCommandEvent *)playOrPauseEve

I am trying to use the AudioQueue to get the raw PCM audio data,but when the program is running ,it will first call four callbacks with an interval of 0.001s(seem to happen at the same time),and then after 0.5s it will call the next four callbacks repeatedly.Does anyone have come across this situation?note:I make reference to an example (SpeakHere);I set my buffer size as 2048 Bytes; here are the part of my programs:_recordFormat.mSampleRate = 8000;_recordFormat.mChannelsPerFrame = 1;_recordFormat.mFormatID = kAudioFormatLinearPCM;if (inFormatID == kAudioFormatLinearPCM){ _recordFormat.mFormatFlags = kLinearPCMFormatFlagIsSignedInteger | kLinearPCMFormatFlagIsPacked; _recordFormat.mBitsPerChannel = 16; _recordFormat.mBytesPerPacket = _recordFormat.mBytesPerFrame = (_recordFormat.mBitsPerChannel / 8) * _recordFormat.mChannelsPerFrame; _recordFormat.mFramesPerPacket = 1;}while I am running the APP the print is shown as follow:(note the time)2015-07-20 16:45:53.235 HelloWorld[4115:239431] bufferByteSize

I'm really new to xcode and Mac Development, so please bear with me.I'm trying to create an Audio Units plugin that will use the Chromium Embedded Framework. I've seen and successfully compiled projects such as this one:https://github.com/acristoffers/CEFSimpleSampleAnd I've been able to create a compiled and loading Audio Unit plugin too. However, When I try to load the Chromium Embedded Framework.framework via copying into the Frameworks folder and use the following build script:install_name_tool -change @executable_path/Chromium Embedded Framework @executable_path/../Frameworks/Chromium Embedded Framework.framework/Chromium Embedded Framework $PROJECT_DIR/Frameworks/Chromium Embedded Framework.framework/Chromium Embedded FrameworkI get this error on test of the AU: AU Validation Tool Version: 1.6.1a1 Copyright 2003-2013, Apple Inc.

My watch alarms are not working at all. I tried to use the nightstand feature, and the watch would light up at the time the alarm was set for, and indicate the alarm had been triggered. However, there was no sound or haptic alert. Tried this several times, with a reset, and no change in behavior. Checked mute/sound etc. and tried several configurations: haptic 0, 1, 2, sound mute on/off etc. No change in behavior. Pretty consistent when it's in nightstand mode: watch would light up, ask if you wanted to snooze or not, but no sound or vibration. It's worse outside of nightstand: when the alarm should go off, nothing happens at all. I'll go back into the alarm app, and the triggered alarm is now set to off. This happens repeatedly and consistently. WatchOS 2 beta 3
