Since I have no sound card, how do I configure my system to use the dummy PCM driver and use the pcm.file plugin?

Thanks, -Caleb

audio into a file, or maybe it would create another device that could be read simply by 'dd' or some custom command. Then I'd pipe the data into
It works with named pipes as well.
