[alsa-devel] Grab PCM stream into file

Hello,

I'm playing with embedded system without any hardware sound device. Strategically we'd like to forward PCM stream from ALSA clients on user level to proprietary application. As initial proof of concept stage I'd like to grab sound from ALSA application, for instance Firefox displaying YouTube clip inside flash plugin and to store output PCM stream into file on local disk.

Please advice how I could achieve this goal.
