donno. i can start audacity fine when running jack. maybe it is the
window manager's sound server thats claiming your /dev/dsp? with GNOME
you can look in the menu Preferences => Sound. unselect the "enable
sound server startup" option.

you are supposed to run LADCCA as normal user. what version of LADCCA
do you have? i got the same message when i ran the older 0.3.1 from the
RH9 iso images. the current version 0.4.0 should have this fixed. see
also this recent thread on the ladcca mailinglist:

well my computer also has 256MB and it also swaps heavily every now and
then, consuming lots of cpu cycles. but it has never caused me any
(recording) problems until now, i think audio apps run at higher

is the swapping causing you problems???
