Enter the following: | Code: | | echo "media-sound/jack-audio-connection-kit alsa jack-tmpfs sse mmx cpudetection" >> /etc/portage/package.use |
Then recompile jack-audio-connection-kit. This assumes that your machine is at least a P-III. If not, drop the sse. The most important setting is the jack-tmpfs setting. It lets jack use memory for caching operations rather than using the hard drive.
Also, for best results, you need to tweak your kernel as follows:
| Code: | Processor type and features -->
[*] Tickless System (Dynamic Ticks)
[*] High Resolution Timer Support
[*] Single-depth WCHAN output
[*] HPET Timer Support
Preemption Model
(*)Preemptible Kernel (Low-Latency Desktop)
Timer frequency
(*) 1000 Hz |
There are those who also extol the virtues of the fully preemptible kernel. I am sure that there are some out there who have actually managed to get said kernel monstrosity to be more than an irritation and a source of unending crashes. I am; however, not one of those people. I have had no luck with the FPK, so I do not recommend it.
Blessed be!
Pappy

I apologize for the inconvenience, however, I do not enjoy encountering religious/spiritual terminologies more than I appreciate or value being helped/assisted. Sorriez =/
