Hi,
i wonder if there's a pcm plugin available, that is writeable and also
readable in a sense that everything that is written to it, will be
readable again. this could be useful for recording alsa app output if
the hw does not support capturing the line-out or mix.
Let's call this plugin "redirect" for now.
.asoundrc:
pcm.redirector {
type redirect
# we don't need a slave, since this is purely virtual
}
pcm.mymulti {
type multi
# here we combine "redirector" and "hw:0,0" into one device. too lazy
to look up the syntax
}
pcm.sniffable {
type route
slave.pcm "mymulti"
slave.channels 4
ttable.0.0 1
ttable.1.1 1
ttable.0.2 1
ttable.1.3 1
}
now, when i do
aplay -D plug:sniffable
i should be able to hear the playback and record that stuff by using
arecord -D plug:redirector
I know there exists the file plugin, but i think using a recording app
for this is more convenient.. Is this possible and is this feasible? and
did i maybe just miss something in the pcm plugins docs and it already
works?
