dan –

same thing happened to me around november 2009… eventually after uninstalling and reinstalling etc, the audio problem went away.

it just started coming back again yesterday for no apparent reason. and i don’t even have kona drivers, i only work with video.

pleeeease let me know if you found a solution. i can’t work with this problem. the audio crackling is so loud and sudden that it makes me jump everytime. and once it starts, it also starts affects the sound system wide.

problem only ever happens when i’m in FCP.

alex….
this may be a very dumb question, but i assume you’ve tried running all the software updates too, right?
i am trying again… after that i am thinking of selling my MBP and buying a 2nd hand one that’s not on snow leopard.

hi alex,

yes, it got to the point where i thought it must be me being a complete idiot but at least now i’ve found one other person who has the EXACT problem.

i’ve tried everything. i’m still at square one.
do you think it might have sthg to do w/ using the FW800…? i’ve always set my renders and audio files to go on my external.
i haven’t really tested it w/out the FW800 because i have literally nothing to work w/ on my internal HD. and if i can’t use an external HD w/ the MBP, then the machine is simply useless for video editing.

hi alan,

so i went back to the apple store, and had a tech guy who is an experienced editor in FCP. we looked at console and looked at the log and saw that i kept getting an error message looking for an audio plugin (/library/audio/plugins) – sthg like that, so he suggested that i move that plugin so it couldn’t pull that anymore. did that, problem still there.

he said otherwise it’s really my workflow and i shouldn’t mix 44.1 w/ 48khz. so i converted all my audio to 48, problem comes back.

then i noticed that my audio render files and autosave files weren’t where i expect them to be (ie where i defined it in FCP) in fact i can’t seem to find where they are being saved regularly at all…. i suspect that might be part of the problem?

then i also repair disk permissions every time after the PZZZZP happens, and it’s always the same thing that needs to be repaired…

i wish i could switch back down an OS, but because my MBP is spanking new, i can go below snow leopard…. i’m so frustrated that i want to cry. put in a chunk of money and i have less of a system than before.

if you have any breakthroughs, please please let me know…

hi john,

thanks for responding.

yes, i rendered the tracks. and it still cracks… and the render ends up containing the crack because when i burn a DVD of the movie, it starts cracking (i burnt 2 copies and tested them on a different computer, they both start cracking at about the same place.)

what do you mean by monitoring audio…? i’m just using the standard/default stuff w/ fcp7 and the mbp.

last night i took out the e-sata drive and switched it to a FW800 enclosure and i managed to go alot further before the sound started breaking again. i ran a hardware test and everything came back as fine….

the mbp shipped w/ 10.6 (SL)…so i’m not sure how well fcp 6 will work on that?

ok, i’ve wiped my system and done a clean install.
and still have the problem. but for me the biggest issue is that my audio is crackling. it seems to play fine for a while and then it will suddenly go PZZZZPPP. and once it starts it becomes more frequent – to the point where it is impossible to edit.
i have the drop frame issue too, but i can still live with it.
ok, so i have a mixture of audio clips 48, 44… i know i should have them all 48. but given that my old crappy white macbook could handle it just fine w/ barely over 1gb ram, it seems preposterous that my new 17″MBP can’t handle it. (so yes i’m also on snow leopard)

it’s just SD footage. nothing fancy.
i have 2 external hard drives connected. 1 FW800, the other an e-SATA, via an express card.
this is so frustrating that i’m almost going to cry.
is it a FCP 7 problem or something else? would it make sense to go back to FCP 6? i’ve done quite a bit of work in 7 and i’d hate to re-do it all, but right now i can’t do ANYTHING.
