Thanks Arnold. It comes back to the age old question of "What am I
actually trying to do?" I see now that Jamin was never intended for live
effects, which is fine as there are excellent compressors and eq LADSPA's
for those. Now I'm seeing much better how it all fits together.
I realise that the Intel-HDA is a bit of a space filler in my laptop (my
SB is a tower PCI card). I understand that USB soundcards are rubbish if
you want excellent latency (various posts somewhere). So on the hunt for a
new soundcard for it.

Running Jamin, Ardour and Hydrogen is about it at
the moment on my system.
I can get ZYn in there, but Rosegarden is a no. Jamin seems to eat lots of
CPU, which it didn't used to on my other Kubuntu boxes. Anyone got got any
other ideas? What I need is lower latency and I need to be able to run all
the apps I need at the same time. I used to run Hydrogen, Jamin,
Rosegarden and Zyn on my little PC (1.6GHz Athlon, 512M ram, SB Audigy),
but I don't seem to be able to get even there on my 2.6 GHz dual core
Intel with 2G ram, but Intel-HDA. Would really love some help with this or
some links.

You don't want to run jamin with low latency.
</jedi mind trick>
Actually you can't really run jamin at low latency, because the math involved
to do the eq and the cross-over adds at least 10ms. And there is a _lot_ of
math involved, so jamin has always been a cpu-hog. And will always be. After
all its a mastering-tool, not a live-usable effect...
Normally one would create a new session with the stero-exports from all the
songs and route that through jamin. No need for low-latency and not much cpu
used by ardour which leaves all the cycles for jamin.
And Zyn (the original) is not realtime-save either. Don't expect miracles
there.
And don't expect miracles from the Intel-HDA. Except for the name there is
nothing really high about these devices. Better add your SB to that machine
to get quality.
Or invest the next lunch money for a real high-quality device.
Have fun,
Arnold
