Reply to Crackling audio w aggregate device after Monterey upgrade
For me, I like to create an aggregate device so I can use 2 sets of headphones inside of Logic Pro X to mix my songs with whatever artist is in my studio. I like for them to hear the instrumental and their voice while recording, and I also want to be able to hear them as they record simultaneously through the use of the aggregate device that I create with the audio Midi Setup on the computer. So I add in my case my Scarlett 2i2 audio interface along with my pair of headphones(it should pop up as External Headphones inside of the audio Midi Setup app) which I plug directly into my MacBook and my artist that I'm recording will use the headphones that plug directly into the audio interface. When you do this however, you have to make sure to tick Drift Correction for both of the devices that are being linked or however many devices you may have. If you only have 1 ticked, then you will experience weird crackling noise when you try to playback things. As soon as I ticke

Bluetooth Audio Streaming
Does anyone else have to put their watch into airplane mode when streaming music via Bluetooth. I have already completely factory reset my watch and iPhone and continue to have this issue. If the watch is allowed to be connected while Bluetooth audio streaming is occurring, the audio becomes choppy.

NSUserNotification no sound ?
(OSX Sierra) The only time a banner or sound shows / plays is when the app is not in focus, when in focus a message still appears in the desktop notification center but I would like at least a sound when it arrives, preferably including the alert banner. Any suggestions ?

Audio Volume increases by itself
I am using an AVAudioPlayer to play a tick sound once per second in a SwiftUI app. When running the app on an iPhone 16 (18.2.1) the tick sounds increase in volume after a few seconds. This does not happen in the simulator nor on an iPhone SE 2020 (18.1.1).

System Sound Path
I have a system sound( eg: Voicemail.caf) to play through AVAudioPlayer.It has different location in iPhone and iPad /System/Library/Audio.Is there a interface to get path of system sound directly rather than browsing through system directories.If not, could we include this sound file in our app bundle(eg. Resources). Are there chances of App rejection/licensing part if we do so?

Periodic sounds from the background
I appreciate that very similar questions have been asked already, but users of my app have requested certain functionality that simply doesn’t seem possible given the current background mode regulations in iOS. However, many similar apps do have this functionality. So, could it be that I am missing something.Basically, a meditation timer app needs to be able to play bell sounds periodically. Some users, those who meditate for long periods of time for example, like to switch their screens off to preserve the battery charge, and because of that the app needs to play these bell sounds from the background.So far, my solution has been to use Local Notifications to play the sounds as they can be timed accurately and also can play custom sounds.However, there are two issues that my users are unhappy about:1. They want the bell sounds to play even when the silent switch is on (they don't want to be disturbed by other notifications, but do want the meditation bells)2. They want the

AVAudioEngine no sound from Mac mini built-in audio devices
Hi,I've tried to get some audio things going on a new Mac mini 8,1 macOS 10.14.2 (18C54), and ran into an issue where there is no output from the built-in audio devices when using AVAudioEngine.Xcode prints this while setting up the AVAudioEngine:[AudioHAL_Client] HALC_ShellDriverPlugIn.cpp:104:Open: HALC_ShellDriverPlugIn::Open: opening the plug-in failed, Error: 2003329396 (what)If the built-in speaker or the headphone jack is selected as sound output device, no sound comes out from my AVAudioEngine app.If I select output via DisplayPort or AirPlay, sound is working, even though above error is also being printed.Here's repo with an example project: https://github.com/nsdvr/avaudioengine_basic_outputIt just plays a .wav file when you press the button. My own project uses a custom AudioUnit generator, and its internalRenderBlock is getting called, so the engine seems to be running fine, there's just silence at the physical outputs.Relevant setup code:- (void) setup

Setting Audio Input node for AVAudioEngine causes outside audio to stop
I'm building an app that will allow users to record voice notes. The functionality of all that is working great; I'm trying to now implement changes to the AudioSession to manage possible audio streams from other apps. I want it so that if there is audio playing from a different app, and the user opens my app; the audio keep playing. When we start recording, any third party app audio should stop, and can then can resume again when we stop recording. This is my main audio setup code: private var audioEngine: AVAudioEngine! private var inputNode: AVAudioInputNode! func setupAudioEngine() { audioEngine = AVAudioEngine() inputNode = audioEngine.inputNode audioPlayerNode = AVAudioPlayerNode() audioEngine.attach(audioPlayerNode) let format = AVAudioFormat(standardFormatWithSampleRate: AUDIO_SESSION_SAMPLE_RATE, channels: 1) audioEngine.connect(audioPlayerNode, to: audioEngine.mainMixerNode, format: format) } private func setupAudioSession() { let audioSession = AVAudioSe

Unwanted "Redeem Code" pop up window when app starts
One of the users of an app I have developed tells me that a Redeem Code window is popping up every time he starts the app. I have not seen this in any of the testing I have done. How do I make sure that this pop up window will not appear? (The app is a fixed price app without in In-App Purchase or Subscription.)
