AudioQueueNewInput callback data is all 0 on macOS app - audiotoolbox

Question

I try to receive audio data from BlackHole2ch or other loop audio plugins on macOS.
I run this test code for macOS app. It callback with all 0 data.
#import "ViewController.h"
#implementation ViewController
#define DEVICE_UID "BlackHole2ch_UID"
static AudioQueueRef s_queue;
static AudioQueueBufferRef s_buffers[3];
- (void)viewDidLoad {
[super viewDidLoad];
[self audioInit];
[self audioStart];
}
- (void) audioInit
{
AudioStreamBasicDescription format;
format.mSampleRate = 44100;
format.mFormatID = kAudioFormatLinearPCM;
format.mFormatFlags = kLinearPCMFormatFlagIsSignedInteger;
format.mBitsPerChannel = 16;
format.mChannelsPerFrame = 1;
format.mBytesPerFrame = 2 * format.mChannelsPerFrame;
format.mFramesPerPacket = 1;
format.mBytesPerPacket = format.mBytesPerFrame * format.mFramesPerPacket;
format.mReserved = 0;
OSStatus err = AudioQueueNewInput(&format, virtual_speaker_callback, (__bridge void *)(self),
CFRunLoopGetCurrent(), kCFRunLoopCommonModes, 0, &s_queue);
NSLog(#"AudioQueueNewInput err=%d AudioQueue=%p", err, s_queue);
CFStringRef deviceUID = CFStringCreateWithCString(kCFAllocatorDefault, DEVICE_UID, kCFStringEncodingMacRoman);
err = AudioQueueSetProperty(s_queue, kAudioQueueProperty_CurrentDevice, &deviceUID, sizeof(deviceUID));
NSLog(#"Set target device:%# err=%d", deviceUID, err);
for (int i = 0; i < NUM_BUFFERS; i++)
{
err = AudioQueueAllocateBuffer(s_queue, BUFFER_SIZE, &s_buffers[i]);
NSLog(#"AudioQueueAllocateBuffer err=%d", err);
err = AudioQueueEnqueueBuffer (s_queue, s_buffers[i], 0, NULL);
NSLog(#"AudioQueueEnqueueBuffer err=%d", err);
}
}
- (void) audioStart
{
OSStatus err = AudioQueueStart(s_queue, NULL);
NSLog(#"AudioQueueStart err=%d", err);
}
static void virtual_speaker_callback(void *inUserData, AudioQueueRef inAQ, AudioQueueBufferRef inBuffer, const AudioTimeStamp *inStartTime, UInt32 inNumberPacketDescriptions, const AudioStreamPacketDescription *inPacketDescs)
{
uint8_t *p = (uint8_t*)inBuffer->mAudioData;
int64_t sum = 0;
for(int i=0;i<inBuffer->mAudioDataBytesCapacity;++i) {
sum += p[i];
}
if (sum == 0) {
NSLog(#"virtual_speaker_callback all Zero ptr=%p data[]=%d %d ...", p, p[0], p[1]);
} else {
NSLog(#"virtual_speaker_callback valid data ptr=%p data[]=%d %d ...", p, p[0], p[1]);
}
OSStatus err = AudioQueueEnqueueBuffer(s_queue, inBuffer, 0, nil);
NSLog(#"AudioQueueEnqueueBuffer err=%d", err);
}
#end
I also try console app with same kind of code. It works with valid callback data.
I enabled "Audio Input" on Xcode capabilities settings.
