Yes, the pcm_jack plugin.

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
