Re: jackd integration

Dear friends,

jackd is not really at the same logical level as alsa.

As far as I know, it needs alsa to work properly, so it works on top. Or am I wrong?

From the documentation:

What is JACK?

JACK is a low-latency audio server, written primarily for the GNU/Linux
operating system. It can connect a number of different applications to an audio
device, as well as allowing them to share audio between themselves. Its clients
can run in their own processes (ie. as normal applications), or can they can
run within the JACK server (ie. as a "plugin").

<snip>
Jack has two sets of parameter options. The first part are specific to running
the jack server. The second part are run time options for how jack interfaces
with the sound driver - currently only ALSA.

The easiest way to start jack is to run this command:

jackd -d alsa -d hw:0

Of course that gives you very little control over what jack does to the audio
stream and which device you use. You can specify a card name by setting up an
.asoundrc file. Visit the online ALSA docs for your card/device to get one.
