Linux – Is it possible to “pipe” audio into the “line in” for a particular program

One thing you can do since I had the same issue is set your OS to use a virtual cable as the default device.

Adobe Flash uses windows defaut and in doing this you will have set firefox to use the VAC for flash based objects (I have verified that flash is sending the audio not firefox for flash based objects or movies)

Then simply use a repeater to send that VAC to your original sound device (soundcard) so you will hear everything like normal but have a VAC tied in the middle that you can work with to do other things.

Ultimately, what worked best for me was to just use a secondary device and send it to my computer with a line-in (use my hp touchpad) this let me drop the huge net of VAC and Repeaters that was causing a delay in my recordings and also let me control that external audio source while in game easily since its on a separate device.

I found a way to do this with Virtual Audio Cable and 1 Skype open.

1. Open VAC Control Panel and make 2 lines
2. Open 4 Audio Repeater(MME)s
3. Set the First to Wave In: Line 1 and Wave Out: Speakers or primary output device
4. Set the Second to Wave In: Primary Microphone and Wave Out: Line 1
5. Set the Third to Wave In: Primary Microhone and Wave Out: Line 2
6. Set the Fourth to Wave In: Line 1 and Wave Out: Line 2

Once this is done set Line 1 as your default playback device in Windows and as Line 2 as your default recording device .

Make sure when you change your Skype settings to also have Line 2 as your microphone and your primary output device as the speakers.

This will make it so both you and your caller can hear any audio that comes from your computer (youtube, spotify, pandora, etc.). You can still talk and you won't hear yourself in an echo and neither will the party on the skype call.
