[linux-audio-user] kernel-2.6.14.2-lsm only slightly better...

Hi again! I built and installed 2.6.14.2. Like the standard FC4 kernel on this machine I had to disable acpi - I don't know if that could hurt anything besides battery performance... I built and installed realtime-lsm-0.1.1, running it with modprobe gid=500 any=1. I built jackd using: --with-default-tmpdir=/dev/shm (Fedora's tmpfs ram device, or so I think) (BTW: my fstab is weird about jacks temp directory (# This file is edited by fstab-sync - see 'man fstab-sync' for details (LABEL=/ / ext3 defaults 1 1 (LABEL=/boot /boot ext3 defaults 1 2 (/dev/devpts /dev/pts devpts gid=5,mode=620 0 0 (/dev/shm /dev/shm tmpfs defaults 0 0 (/dev/proc /proc proc defaults 0 0 (/dev/sys /sys sysfs defaults 0 0 (LABEL=SWAP-hda5 swap swap defaults 0 0 (none /dev/shm tmpfs defaults 0 0 (/dev/hdc /media/cdrecorder auto pamconsole,exec,noauto,managed 0 0 (none /dev/shm tmpfs defaults 0 0 --enable-capabilities=0 (I thought this was bad 'cause the ccrma jack.spec file as capabilities disabled. Same results with enabled) --enable-posix-shm --disable-oss The best I can do with jack without out more then the 13 initial XRUNS is: /usr/local/bin/jackd -R -P70 -u -dalsa -dhw:0 -r48000 -p256 -n2 -m -H -M ...though qjackctl says cannot use real-time scheduling (FIFO at priority 69) [for thread -1211757648, from thread -1211757648] (1: Operation not permitted) cannot lock down memory for RT thread (Cannot allocate memory) the qjackctl statistics window says realtime is enabled. When I run PD I use nice -5 pd but at the above frames/period I get all kinds of static when I change or move windows. I have to go back to -p1024 to avoid thoes pops (A/D/A sync errors PD calls them) So I guess I am ready to try changing the IRQ's of my sound cards (Mark?) . What should I do to make my machine perform better? I am going to ask the pd-list about pd optimizations. Thanks! -thewade
