Close, more like

                                +-->[some jack recorder]

Does it let you type in the alsa device, or just give you a drop-down 
box? You need to be able to use the default ALSA device or be able to 
type in an arbitrary string. A drop-down box usually means the author's 
worldview is limited and he thinks there are only hardware devices, and 
it won't work.

On the other hand, if you can choose OSS or PulseAudio, that opens 
another door.
