======================================================================
|
|
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_enable="YES"
|
|
jackd_user="{your-jack-user}"
|
|
jackd_rtprio="YES"
|
|
jackd_args="-R -doss -r{sample-rate} -p1024 -n3 -w16 \
|
|
--capture /dev/dsp{N} --playback /dev/dsp{N}"
|
|
|
|
Where:
|
|
- 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.
