JACK is a low latency audio server, written for POSIX-conformant operating
systems.  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 (i.e. as normal applications), or
can they can run within the JACK server (i.e. as a "plugin").
JACK was designed from the ground up for professional audio work, and its
design focuses on two key areas: synchronous execution of all clients, and
low latency operation.

- ALSA: off
- DOXYGEN: off
- SNDIO: off
It is recommended to run Jack with real-time priority (-R).
The recommended way to start Jack is to add the following
lines to /etc/rc.conf:
jackd_args="-R -doss -r{sample-rate} -p1024 -n3 -w16 \
--capture /dev/dsp{N} --playback /dev/dsp{N}"
- your-jack-user: is the user who is going to use jack; currently
only one user is supported
- sample-rate: can be 44100, 48000, etc.
- /dev/dsp{N}: your OSS devices, usually /dev/dsp0
Please note that the port option COOKEDMODE is "on" by default, which
makes your system to automatically scale the sample-rate between
Jack and audio hardware. One reason COOKEDMODE=on is because
Jack's OSS driver doesn't support some sample-rate and hardware
combinations when COOKEDMODE=off. To achieve the best sound quality
please make sure your hardware natively supports the sample-rate set
in jackd_args, and set COOKEDMODE=off.
