dsnoop

["David E. Storey" <dave@tamos.net>]

Folks,

Would anyone be so kind as to offer up an example of using dsnoop? I'd
like to use jack to perform all kinds on monitoring on a device and use
an alsa app, namely arecord, to do the actual recording. I've tried
using the jack plugin and while it works, when I hit CTRL-C on arecord
to stop recording, it pretty much halts jack.

When I use dsnoop now, if there's nothing using the device, it returns:

set_params:810: Channels count non available

And if something, like jack, is using the original device, it just sits
and waits without doing much of anything. My .asoundrc file looks a
little something like:

pcm.intel8x0 {
        type hw
        card 0
}

ctl.intel8x0 {
        type hw
        card 0
}

pcm.snoop {
        type dsnoop
        ipc_key 3346
        slave { pcm "intel8x0" }
}

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
        }
}

Any help would be GREATLY appreciated. And if I should be using another
list, please let me know kindly.

d!
