Qt中的QAudioDeviceInfo::availableDevices接口可以轻松的获取到音频设备信息

    //获取输入音频设备名称    QVector<QString> aDeviceListI;    QList<QAudioDeviceInfo> audioDeviceListI = QAudioDeviceInfo::availableDevices(QAudio::AudioInput);    foreach (QAudioDeviceInfo devInfo, audioDeviceListI)    {        QString strName = devInfo.deviceName();        if (devInfo.isNull()) continue;        if (strName[0] == 65533) continue;        bool bFound = false;        foreach (QString dev, aDeviceListI) {            if (strName == dev){                bFound = true;            }        }        if (bFound == true) continue;        aDeviceListI.push_back(strName);        ui->comboBoxInput->addItem(strName);    }    //获取输出音频设备名称    QVector<QString> aDeviceListO;    QList<QAudioDeviceInfo> audioDeviceListO = QAudioDeviceInfo::availableDevices(QAudio::AudioOutput);    foreach (QAudioDeviceInfo devInfo, audioDeviceListO)    {        QString strName = devInfo.deviceName();        if (devInfo.isNull()) continue;        if (strName[0] == 65533) continue;        bool bFound = false;        foreach (QString dev, aDeviceListO) {            if (strName == dev){                bFound = true;            }        }        if (bFound == true) continue;        aDeviceListO.push_back(strName);        ui->comboBoxOutput->addItem(strName);    }
