[alsa-devel] Grab PCM stream into file

[Alexander Indenbaum]

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.
