How to record the audio in my system

[Rajagopalan-M]

Hi Kapoor,

I have utilized your ruby gem to capture both video and audio during recording. However, I recently acquired a new system and unfortunately, I am unable to locate the audio system. When I ran your command, it presented the following message.

C:\A\Rajagopalan\VideoRecorder>ffmpeg -list_devices true -f dshow -i dummy

I used this one Microphone Array (Intel® Smart Sound Technology for Digital Microphones in

advanced = { log: 'AppData/Logs/recorder.log', f: 'dshow', i: 'audio="Microphone Array (Intel® Smart Sound Technology for Digital Microphones)"' }
ScreenRecorder.ffmpeg_binary = File.expand_path("VideoRecorder/ffmpeg.exe")

And it's recording the voice which is going through the mic not what's coming through the speaker and it's expected. Last time In my system, I found these two in my system

However, I am currently unable to locate this feature on my current system. What steps can I take to address this issue and find a solution?

I encountered a new bug where the video recording works fine, but unfortunately, it is not capturing the audio. Could you kindly take a look at it, please?
