Hi
I'm into shapeing up my system to work better. I have installed a Debian
lenny and migrated 64Studio multimedia packets on to it, and use
64studio's kernel 2.6.21-1-multimedia-486, then installed irqbalance and
try to find the best setup for my RME Hammerfall Multiface card.
I use a lenove T61 laptop and my problem is that the PCMCIA card share
IRQ with some usb device on IRQ 16:
debian:~$ cat /proc/interrupts
CPU0 CPU1
16: 5328 20016 IO-APIC-fasteoi uhci_hcd:usb4, yenta,hdsp
I want to move my hdsp to another IRQ, but can't figure out howto, it is
a matter of firmware version on my Multiface card ? I can't move the
PCMCIA card since there is only one available slot....

Ok, of cause Iv'e had looked im my BIOS, but how do i match the IRQ's
numbers here "A to E" to the ACPI's ? As default in the BIOS they are
set to IRQ11, If I try to disable og move some of them it does not
change anything, which make me belive that Linux handle the devices
during system startup and therefore can be ajusted to my needs ? I just
dont know how.
But thanks anyway.

I think I just did a trial'n'error with the BIOS settings and cat
/proc/interrupts.

Afaik most mainboards have hard-wired interrupts for the devices and the
slots.
So in a desktop-system moving devices in their slots is a way of changing
their interrupt.
With a laptop you are out of luck.
Then the only solution is to make sure that only one of the sharing devices is
used at a time. On my laptop fw and wifi are sharing and when I shut down the
network, I don't get problems with the firewire. Whereas on my big machine
one of the usb-ports is sharing with the graphics. Back when I used usb-audio
I figured which port it was and used that only for the mouse, not for
audio...

You can't. Unless you have a ThinkPad. Or a desktop machine where you can move cards
to different slots.

Ok I'm begining to be a little happy :) I'ts down to one usb port
sharing with the hdsp. I manage to get the latency under 3ms which I
find farily good, I made a little script from documentation I found on
the net, and placed it in my rc system:
SCRIPT START
#/bin/sh
#set -v
#script for tuning latency under Linux
#Setting what soundcard you want to work on
#export card="RME"
#Find your soundcards place on the PCI bus and put it in a variable
export Sound_Card_ID=`lspci|grep "RME"|cut -d ' ' -f1`
#allowing medio long bursts for all PCI devices
setpci -v -d *:* latency_timer=b0
#..then maximize latency timers for audio
setpci -v -s $Sound_Card_ID latency_timer=ff
SCRIPT END
Then i got this result, which you can se here:

But is it possible to get ZynAddSubFX to run lower as the 5.3ms internal
latency ?
I don't know if thats an issue, but if I load tons of tones on the
keyboad the sound getting noisy but there are no X-runs, and playing
together with Hydrogen the drum sound don't seem to be affected from the
noisy sound from ZyndAddSubFX.

ZynAddSubFX itself is not RT-save. There are some ports of the various
zyn-engines to other synths that are rt-save (whysynth for example includes
zyn's PAD-engine).

See above, its zyn's fault...

There is setting about internal buffer size.
