Hello,
I'm playing with embedded system without any hardware sound device. 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. I got an advice to use File extension. So I defined following /usr/share/alsa/alsa.conf
pcm.default {
type file
file /tmp/pcm.out
}
But when alsa lib still complains about
"Unknown PCM plughw:0,0"
"Cannot open shared library /usr/lib/alsa-lib/libasound_module_pcm_file.so"
I have a nasty feeling that syntax of my /usr/share/alsa/alsa.conf is broken beyond recognition. I wonder what is the correct way to define my situation:
* No real audio devices
* All sound is output goes to file as PCM stream
Do you have a clue?
