What does --with-jack do? Does it just compile the jack pcm
Yes, the pcm_jack plugin.
And
what can I do with the jack pcm? Is it possible to send the sound
played on this device, for example with aplay, to the jackd? Is
Yes, and record from jackd, for example with arecord.
aplay and arecord are the only applications tested. But they _do_
work. you will need to configure the plugin like this: (in your
asound.conf)
pcm.jackplug {
type plug
slave { pcm "jack" }
}
pcm.jack {
type jack
playback_ports {
0 alsa_pcm:playback_1
1 alsa_pcm:playback_2
}
capture_ports {
0 alsa_pcm:capture_1
1 alsa_pcm:capture_2
}
}
now, you can aplay -Djackplug
If I try to ctrl-C out of aplay while it is playing, playback stops and
it prints "Aborted by signal Interrupt..." twice and hangs in there.
Further ctrl-C's have no effect. State of the process in a ps listing is
"SL". A "kill pid" from root makes it print "Aborted by signal
Terminated..." but the process is still there (same state). Killing the
jack server finally makes aplay quit.
