No Audio Despite of setting the Speaker(Playback) & Recording(Internal AUX)

We are capturing the audio stream from the virtual audio driver like vbcable or Loopbe. I want to do the same with this driver (capture samples from the Internal AUX Jack). Is this even possible? How can I achieve this?

Hi @Raj123456788, that's a blind device which I should probably remove. It will not do anything.

If you want to capture the PCM output you might want to write a simple multicast listener that can dump the data into a file. This can be either onbox or offbox. For inspiration, look at the .NET code of the Windows receiver or the Pulsaudio Linux receiver.

Hope that helps!

@duncanthrax : can you please send me links that would help? We have tried this but it does not compile. We are looking for a virtual audio driver open source. Our expertise is C#. Any help will be appreciated. Thnx

Check ScreamReader, around this line:

In addition to sending the PCM data to the audio subsystem, write it to a file.
