Hi Anthony,
The jackstart command only works if you have realtime enabled, which means
configuring your kernel to support it and building the realtime module from
source. Try that if you're interested; but to launch jack without realtime
support just use the jackd command - all options are the same.
That's what man jackd says, but I just tried jackstart on my realtime-enabled
box and got the same error as you! However jackd --realtime does work. Go
figure.
I suggest using qjackctl to manage jack - makes it easy.
As for your other issues, it could be a lot of things; try disabling the KDE
sound system, and if you really only have soundcore loaded, make sure the
snd_* modules are loaded, including the one for your soundcard.
Then run alsaconf, check that jack is not running (some apps are not jack
aware and won't work), check your mixer settings to make sure nothing is
muted; then play a file using any ordinary alsa-using program, like say,
aplay.
If none of this works, post again with the errors.
Good luck,
John
