    44== Get a real-time kernel == 
    55 
    6 Quite a few people have reported good results with 2.6.31.4-rt14. Generally, it's advisable to get the latest [http://kernel.org/pub/linux/kernel/v2.6/ stable release]: if a friend tells you 2.6.X is good, and by the time you download, 2.6.X.Y is out, go for that. Low-latency behaviour will very likely be identical for the same X, but you will also some important security fixes. Same goes for the [http://kernel.org/pub/linux/kernel/projects/rt/ realtime patch] release. Always get the latest - they usually get better, not worse.

    88See if your distribution has the in-kernel config list enabled: search for a file named {{{/proc/config.gz}}}. If it exists, unzip it to your kernel source tree and rename it to {{{.config}}}. It will contain the kernel configuration of your currently running kernel, which you can use as a base. Then proceed as described in [http://www.alsa-project.org/main/index.php/Low_latency_howto the low latency howto at alsa-project.org]. It's slightly out-of-date but mostly usable.
