Hello sweet, sweet list!
I am wondering what the state of low-latency high-performance
linux audio is?
I am running 2.6.10 on fedora core with gnome and a few other
processes (see post script for top | awk \'{ print $13 }\' output)
and the realtime module (modprobe realtime gid=mygid).
For performances I stop xscreensaver and cups.
I saw lots of emails about rlimits: is that some new
realtime-esque kernel option?
My hardware:
AMD64 3400+ laptop (early version xtremenotebooks raptor)
1GB RAM
ATI Radeon 9600 M10 graphics card (never really set up under linux)
HDSP Hammerfall w/ Multiface
Fedora Core 3T1
Jack 0.99.43 and qjackctl
Xorg
Release Date: 18 December 2003
X Protocol Version 11, Revision 0, Release 6.7
Build Operating System: Linux 2.4.21-14.ELsmp x86_64 [ELF]
Current Operating System: Linux musicbox 2.6.10 #1 Thu Dec 30 21:12:01 MST 2004 x86_64
Build Date: 02 July 2004
Build Host: thor.perf.redhat.com
Mainly running PD (pure-data)
My questions are:
Best kernel
Best X (manager and/or settings)
Best graphics setup for ATI (if it affects audio performance)
Distro - a distro is just a starting point, right?
A tweeked debian machine and a tweaked fedora machine each
could each be made as fast as the other, no?
Is there a site that has the current state of high
performance linux audio somewhere?
Thanks for the help, one and all!
