Segmentation fault with AudioHardwareCreateAggregateDevice

[TnTora]

Describe the bug Calling AudioHardwareCreateAggregateDevice from the CoreAudio framework results in a segmentation fault

Platform information

• Python 3.13.1
• installed via homebrew
• macOS 15.2 (x86)

To Reproduce

import CoreAudio
aggregate_device_properties = {
    CoreAudio.kAudioAggregateDeviceNameKey: "TestAggregateDevice",
    CoreAudio.kAudioAggregateDeviceUIDKey: "com.user.TestAggregateDevice",
}
stat, aggr_id = CoreAudio.AudioHardwareCreateAggregateDevice(aggregate_device_properties, None)
print(f"aggr_id: {aggr_id}")
CoreAudio.AudioHardwareDestroyAggregateDevice(aggr_id)

Expected behavior Give the same result as the following code

#include <CoreAudio/AudioHardware.h>
#include <CoreAudio/CoreAudio.h>
#include <Foundation/Foundation.h>

int main() {
    OSStatus status;
    AudioObjectID aggregate_device_id = 0;
    NSDictionary* aggregate_device_properties = nil;

    aggregate_device_properties = @{
        @kAudioAggregateDeviceNameKey : @"TestAggregateDevice",
        @kAudioAggregateDeviceUIDKey :
            @"com.user.TestAggregateDevice",
    };

    status = AudioHardwareCreateAggregateDevice(
        (CFDictionaryRef)aggregate_device_properties, &aggregate_device_id);

    printf("aggr_id: %u\n", aggregate_device_id);
    
    AudioHardwareDestroyAggregateDevice(aggregate_device_id);
}

Additional context I'm trying to replicate some of the functionality of this code.

And here is the output from lldb
