I actually went back and forth over the issue with Falktx on irc and got it
to where audio would work but it's extremely choppy when it plays.

After trying 'every trick in the book' and also remembering that I had the
exact same problem with kdenlive (choppy audio) in 8.04 I've come to the
conclusion that there's an issue with this onboard sound card.

For the record, it's an Intel Corporation 82801EB/ER (ICH5/ICH5R) AC'97
Audio Controller (rev 02).

Damn.

Thanks for the input, all.

What's the best way to kill jack in KXStudio then?

.....and then only have ALSA running?

I'd like to attempt some video editing (tall order, I know)

No, not so tall anymore. KDEnlive 0.7.8 runs much better than its 0.6-serie=
s for me. Not entirely flawless but perfectly usable for productive work.

but this audio
issue is killing it.

I'm assuming that after I kill JACK, I can restart it with 'pulse-j=
ack' and
all should be well, no?

Also, does avidemux work with JACK?

I also recommend Open Movie Editor if you want perfect Jack-integration for=
a videoapp. Anyway, I would prefer to use KDEnlive for film-editing, expor=
t a video, do the Audiostuff in Ardour synced to xjadeo playing that video =
or synced to OME playing it.

>From my experience I suspect one of these problems:

1.) the ogv could be not very well supported and/or in a very high resoluti=
on.
2.) you have certain effects running on the video (especially color-correct=
ion modules gave me some trouble here...)

Both issues are related to very high system load. If there is really someth=
ing broken, we would not talk about stutter but about crashes/freezes.

kdenlive also has jack support iirc.

Nope, it's on todo.
