May I know what does "record sound card" mean? Do you mean you want to capture audio from a capture device? If it isn't, can you show more details about your expected behavior? In addition, why don't you want to use MediaCapture api?

I want to capture system audio (sound card), not device audio (microphone). I know that the MediaCapture API can capture microphone audio, but this is not what I need.
