The manual install guide is good to go, but the stage4 install guide is still being worked on.
You need to configure some settings for real-time audio processing on Linux. Start by adding the realtime and audio groups:
> groupadd realtime > groupadd audio
Create a regular user and add it to the realtime and audio groups.
> useradd -m -G users,wheel,audio -s /bin/bash (username) > passwd (username) > gpasswd -a (username) realtime > gpasswd -a (username) audio
> nano /etc/security/limits.conf
Since the default file is entirely commented, delete all lines in the file and replace it with the following:
* hard rtprio 0 * soft rtprio 0 @realtime hard rtprio 20 @realtime soft rtprio 10 @audio - rtprio 99 @audio - memlock unlimited
To accommodate any IEEE1394 devices you may have, you need to create a new file:
> nano /etc/udev/rules.d/fw.rules
Add to this file the following:
KERNEL=="fwx", GROUP="audio", MODE="0664" KERNEL=="fwy", GROUP="audio", MODE="0664" KERNEL=="fwz", GROUP="audio", MODE="0664"
where fwx, fwy and fyz are your Firewire devices. You can find these by turning on all of your Firewire devices and looking for /dev/fwn, where n is an integer. If you have one device, the above file should have one line. If you have five, you should have five lines.
