I am still unable to run Jack at anything less than
1024 without having
Xrun hell. I set the HD to DMA "on" I had apm as opposed to acpi
running...turned it off and found no difference.
Check that your CPU speed is not getting screwed up by the power
management (i.e. you have the full 650 MHz). I don't know if it's even
a problem for Dell laptops, but it was/is for certain Thinkpads.
I notice that running Ardour (Beta .9beta 9 RPM from
Thacs RPMs), after
I have fired up Jackstart or Jackd-realtime from Qjackctl with -d alsa
hw:0 1024 2 as root and then fire up Ardour and add a track, the pcm
chain is connected (also visible in Qjackctl "Connect")and I have sound
but the pc starts running slow and the Hard drive light is constantly
on. I'm not recording anything...is this Jack writing to disc? I only
have 128 megs in this machine...
It's worth maxing out the RAM in your laptop. I have a Thinkpad with
similar specs, and I found upgrading from 128 to 384 Mb RAM made a huge
difference in performance. Make sure you get the right kind, or at
least a compatible kind. It seems likely that this is the problem; even
if it isn't, it's still a very worthwhile (and cheap) upgrade.
