[Alsa-user] output from one application to input of another

[Michael Di D. <mdi...@gm...>]

Here's what I'm trying to do, though I'm not sure it's possible.

I have one application that takes input via the line-in port on my computer
It then processes the sound and outputs the audio to the speakers

I want to take the audio destined for the speakers and re-route it to
another program that is not alsa aware.  It's looking to open
/dev/dsp, which reports busy if i try to load both programs currently

Is there a way to take the output from the first application and
redirect it into a /dev device for input into this second program?

I poked around the net, but could not find anything that related, I'm
running Centos 5.5 i386 latest patches

Thanks
