Thanks for responding Tamas. I will definitely report the bug. Would there
be any work-arounds to this issue? Is there a way to change the default
device if it is an aggregate prior to instantiating an AVAudioEngine?

Re: AVAudioEngine Aggregate Device Crash

2018-02-09 Thread Tamas Nagy

This is a known issue - at least DTS confirmed this is an AVFoundation bug - , 
exists from 10.10 Yosemite if I can recall. Please report it at 
bugreporter.apple.com . I’ve reported it around 
6 months ago, but nothing really happened since then. The more bug reports to 
more chance this will be fixed in 10.14.

Thanks!

AVAudioEngine Aggregate Device Crash

2018-02-09 Thread Christopher Baine

Hello all,

I am having an issue with AVAudioEngine starting with an Aggregate Device
as the default output device. Below is my sample code, which works fine
with any other output card selected. When I select an aggregate as my
default device in the System Preferences, it crashes on the
engine.connect() call. I am on 10.13.1, and am having the same issue on
10.12.6


import Cocoa

import AVFoundation


class ViewController: NSViewController {



let engine = AVAudioEngine()

let player = AVAudioPlayerNode()



override func viewDidLoad() {

super.viewDidLoad()



addPlayer()

startEngine()

}





func addPlayer() {

engine.attach(player)

engine.connect(player, to: engine.outputNode, format: nil)

}





func startEngine() {

do {

try engine.start()

}

catch {

print("ERROR", error)

}

}




Here is the log:

*2018-02-09 13:53:53.014046-0500 TEST_AVEngineAggregate[18127:655111]
[DDAgg] DefaultDeviceAggregate.cpp:58:GetPreferredStereoChannels: Error

[General] required condition is false: isInput ? auv3().canPerformInput :
auv3().canPerformOutput*

*...*


I have tried checking to see if the preferedChannelLayout, or the
preferredStereoChannels is an issue, via:


func getOutputCardPrefferedChannels(id: AudioObjectID) {

var propAddress = AudioObjectPropertyAddress(mSelector:
kAudioDevicePropertyPreferredChannelsForStereo, mScope:
kAudioObjectPropertyScopeOutput, mElement: kAudioObjectPropertyElementMaster
)

var prop: Array = Array(repeating: 0, count: 2)

var propertySize: UInt32 = UInt32(MemoryLayout.size(ofValue: prop))

let err = AudioObjectGetPropertyData(id, , 0, nil,
, )

print(err, prop)



}





func getOutputCardPrefferedChannelLayout(id: AudioObjectID) {

var propAddress = AudioObjectPropertyAddress(mSelector:
kAudioDevicePropertyPreferredChannelLayout, mScope:
kAudioObjectPropertyScopeOutput, mElement: kAudioObjectPropertyElementMaster
)

var prop: AudioChannelLayout = AudioChannelLayout()

var propertySize: UInt32 = UInt32(MemoryLayout.size(ofValue: prop))

let err = AudioObjectGetPropertyData(id, , 0, nil,
, )

print(err, prop)

}




Which prints:

** AGGREGATE *


*Aggregate Device*

*0 [1, 2]*

*0 AudioChannelLayout(mChannelLayoutTag: 0, mChannelBitmap:
__C.AudioChannelBitmap(rawValue: 0), mNumberChannelDescriptions: 4,
mChannelDescriptions: __C.AudioChannelDescription(mChannelLabel:
4294967295, mChannelFlags: __C.AudioChannelFlags(rawValue: 0),
mCoordinates: (0.0, 0.0, 0.0)))*



*** BUILT IN OUTPUT *


*Built-in Output*

*0 [1, 2]*

*0 AudioChannelLayout(mChannelLayoutTag: 0, mChannelBitmap:
__C.AudioChannelBitmap(rawValue: 0), mNumberChannelDescriptions: 2,
mChannelDescriptions: __C.AudioChannelDescription(mChannelLabel:
4294967295, mChannelFlags: __C.AudioChannelFlags(rawValue: 0),
mCoordinates: (0.0, 0.0, 0.0)))*



These don't throw any errors.


The aggregate consists of the Built In Output, and SoundFlower 2ch. (So 4ch
output total) I have also tried making an aggregate with only the built-in
output as well as aggregates with other output cards, but it also crashes.


Any help or thoughts on where to begin troubleshooting this would be
greatly appreciated!

Thanks,

Chris
