This code works fine, find the device name success.

auto list = CoreManager::getInstance()->getCore()->getExtendedAudioDevices();
auto audioDevice = find_if(list.cbegin(), list.cend(), [&] ( const std::shared_ptr<linphone::AudioDevice> & audioItem) {
   qWarning() << "[set capture device] devId " << QString::fromStdString(audioItem->getId());
   return audioItem->getId() == devId;
});

Don't know what the problem is

    CoreManager::getInstance()->getCore()->setCaptureDevice(devId);
    CoreManager::getInstance()->getCore()->setInputAudioDevice(*audioDevice);
    emit captureDeviceChanged(device);
    resetCaptureGraph();

According to log analysis, Diff MSAlsaRead MSVolume MSResample Addresses vary widely.

Need help, Thank you!

void SettingsModel::resetCaptureGraph() {
deleteCaptureGraph();
createCaptureGraph();
}

The final code verification is createCaptureGraph() issue.
more analyze:
createCaptureGraph();
--->mSimpleCaptureGraph->start();

Solution：
Setting audio annotating resetCaptureGraph, There is no functional impact.
