I have had my best results with defining a custom runlevel. ksysv
helps with this if you run a system that uses SysV style init (this
would include Debian and Ubuntu). Then you can do a simple "sudo
telinit 3" to turn off all daemons that may interfere with audio
performance (usually, on Debian at least, 2 is the default run level,
and 3-5 are available for custom usage, 0 is halt, 1 is single user,
and 6 is reboot). One approach is to copy the /etc/rc.1/ directory to
/etc/rc.3/ and turn things on selectively until it makes a usable
system. This is also a great way to learn about all those little tasks
that are idling in your htop display, and what they are doing. This is
a bit of work, but is worth it.
