如何从聚合CoreAudio设备启用/禁用输入或输出通道？

#include <AudioToolbox/AudioToolbox.h>

void enableDisableChannel(AudioDeviceID deviceID, AudioObjectPropertyScope scope, UInt32 channel, Boolean enable) {
    AudioObjectPropertyAddress propertyAddress;
    propertyAddress.mSelector = kAudioDevicePropertyElementMaster;
    propertyAddress.mScope = scope;
    propertyAddress.mElement = channel;

    UInt32 enableValue = enable ? 1 : 0;
    AudioDeviceSetProperty(deviceID, &propertyAddress, 0, NULL, sizeof(UInt32), &enableValue);
}

void enableDisableChannelsInAggregateDevice(AudioDeviceID aggregateDeviceID, Boolean enable) {
    AudioObjectPropertyAddress propertyAddress;
    propertyAddress.mSelector = kAudioAggregateDevicePropertyActiveSubDeviceList;
    propertyAddress.mScope = kAudioObjectPropertyScopeGlobal;
    propertyAddress.mElement = kAudioObjectPropertyElementMaster;

    UInt32 dataSize;
    OSStatus status = AudioObjectGetPropertyDataSize(aggregateDeviceID, &propertyAddress, 0, NULL, &dataSize);
    if (status != noErr) {
        // 处理错误
        return;
    }

    UInt32 subDeviceCount = dataSize / sizeof(AudioDeviceID);
    AudioDeviceID* subDeviceList = (AudioDeviceID*)malloc(dataSize);

    status = AudioObjectGetPropertyData(aggregateDeviceID, &propertyAddress, 0, NULL, &dataSize, subDeviceList);
    if (status != noErr) {
        // 处理错误
        free(subDeviceList);
        return;
    }

    for (UInt32 i = 0; i < subDeviceCount; i++) {
        AudioDeviceID subDeviceID = subDeviceList[i];

        // 启用/禁用输入通道
        for (UInt32 inputChannel = 1; inputChannel <= maxInputChannels; inputChannel++) {
            enableDisableChannel(subDeviceID, kAudioDevicePropertyScopeInput, inputChannel, enable);
        }

        // 启用/禁用输出通道
        for (UInt32 outputChannel = 1; outputChannel <= maxOutputChannels; outputChannel++) {
            enableDisableChannel(subDeviceID, kAudioDevicePropertyScopeOutput, outputChannel, enable);
        }
    }

    free(subDeviceList);
}

int main() {
    // 获取聚合设备的ID
    AudioDeviceID aggregateDeviceID = getAggregateDeviceID();

    // 启用通道
    enableDisableChannelsInAggregateDevice(aggregateDeviceID, true);

    // 禁用通道
    enableDisableChannelsInAggregateDevice(aggregateDeviceID, false);

    return 0;
}
