Please don't hit me over the head. I'll freely admit I'm dense. I
couldn't make heads or tails of the .asoundrc documentation (or the many
other links I found on the Web) if my life depended on it. I want to
create a virtual soundcard that is actually a file.
Eventually I was able to move away from square one. I created the
following .asoundrc in my home dir:
pcm.fileout {
type file
slave.pcm "hw:0"
file /home/jcastro/alsaout.raw
}
And aplay works as it should when I use "-D fileout". A file is
generated. Now I want to do the following four things:
1) Free the slave -- I want to get rid of the physical sound card, and
still be able to "play to files". But if I take out the "slave" line,
aplay complains about the lack of it and doesn't play.
2) Convert formats -- I want the generated file to have a fixed encoding
X, bitrate Y, stereo or mono, at my will, regardless of how the
application (aplay in my tests) programs the (pseudo-) soundcard.
3) Use an existing raw file to simulate input (mic) while another
simulates, as already done above, output (speakers).
4) Have the resulting virtual soundcard usable via OSS, by way of the
existing kernel emulation. Would defining it in /etc/alsa.conf instead
of my home dir help?
Can the above be done?
Thanks,
Juan
