I think this might have something to do with kdenlive needing to use ALSA
(not pulse) and pulse running all the time in kxstudio.
?
When I import an .ogv to the stage the audio is a stuttering, digital mess.
My first inclination is to attempt to stop the pulse daemon from running so
ALSA can do its thing.
Would this be a step in the right direction?
Thanks.

kdenlive also has jack support iirc. Can you play the ogv with another
app like mplayer without sound issues?
Thanks.

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) but this audio
issue is killing it.
I'm assuming that after I kill JACK, I can restart it with 'pulse-jack' and
all should be well, no?
Also, does avidemux work with JACK?
Thanks for the input.

No idea, sorry, Haven't trid KXStudio so far.

AFAIK, there are just 4 video tools than can make use of JACK:
Blender's video sequencer (needs a plug-in) and the following VJ
tools: LiVES, VeeJay and FreeJ. Blender's VSE, as well as those VJ
tools are not very well suited for editing video.
It's possible that VLMC, VideoLAN's own NLE, will support JACK, since
VLC supports it, but it's not stable yet and only available from Git
(requires VLC from Git too).
In other words, video production with JACK-driven audio is currently
very clumsy.

So there's no way to stop jack/pulse and just use alsa for this one app?

Yep, indeed it does. Not that I had any positive experience with OME
as video tool, though.

Maybe not what you need for this task, but for editing audio for video then
xjadeo will play your video in sync with jack, so you can see the video in a
window while you scroll around in ardour or your choice of sound editor.
Does not help if you want to edit the video as well.

No, not so tall anymore. KDEnlive 0.7.8 runs much better than its
0.6-series for me. Not entirely flawless but perfectly usable for
productive work.
but this audio
issue is killing it.

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,
export 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
resolution.
2.) you have certain effects running on the video (especially
color-correction modules gave me some trouble here...)
Both issues are related to very high system load. If there is really
something broken, we would not talk about stutter but about crashes/freezes.

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.
