jackd also
includes an alsa to jack bridge, as does the aforementioned
zita-ajbridge. both are easy to use, the latter is very low latency
"bridge" is sort of the wrong word. both these tools make ALSA-supported
audio interfaces available to JACK clients, in addition to whatever backend
the JACK server is using. they do not "bridge" between an application that
uses ALSA and JACK.
sort of.
Just so I understand, the practical result of this is that I can use
an audio application which lacks jack support (perhaps iTunes?) and
send its audio output to jackd?
