Logic x audio fizzle out

i have a problem where my audio fizzles out and the comes back very delayed. i have to restart core audio to correct the problem. sometimes audio fizzles, then comes back in real time, but always eventually returns with the delay.

As I said earlier.....
Note: The latest TC drivers do not specify that they are 10.9 compliant.. They only officially support Mountain Lion 10.8 but they are worth a try with Mavericks just in case...
This is likely why you are having these issues because your Audio Interface is not fully 10.9 (Mavericks) compatible as there are no drivers for it)
Your choices are...
1) Contact TC Electronics and see if they have a 10.9 driver on the way or available as a beta.. or if they have a solution to your issue... I would do this first above everything else.
2) Borrow an FW device and test your FW port in the rare chance you have somehow blown the port.
3) Start again, reformat your Hard Drive and install 10.8 Mountain Lion (if you can) Install Logic...and then install the latest TC drivers... and test. If all is well reinstall your 3rd party plugins etc... Tip: Dont try and take any shortcuts here... like trying to install Logic and its content or 3rd party libraries etc..from Time Machine backups... It just often doesn't work well at all and is likely to cause your more issues in the long term Restoring Logic projects and other personal data like docs and photos from TM backups is usually okay however..
4) Buy a new Audio Interface from a company that actually brings out drivers in line with OS X Updates.. so you don't have these kind of issues.. (Motu or RME to name but two..)

Logic Pro X - Record in time - Logic moves audio automatically out of time

I have a mac book pro
OSX Version 10.8.4
2.3 Ghz intel core i5 processor
8 GB memory 1333 MHz DDR3
Latest version of Logic Pro x
When I record an audio track using the mac book pros built in microphone, I sing or play an acoustic part in time (yes in time, I'm not dodgy time-wise!)
But when I play back the audio, Logic has shifted the audio file to be out of time by some way, from the click
- it also does this when I connect up my mbox 2
any ideas anyone?

Sounds like you are not monitoring through your soundcard or logic and the latency of your audiobox/soundcard is placing the recording too late. Try to reduce the buffer to 256 or 128 in your mbox mix display, and use software monitoring if you can.

Audio cut out and midi miss sync

Lately I have been getting audio cut out, and the missing, 'error while trying to sync audio and midi'.
I thought it was that I had too many instances of virtual instruments. So I mixed the song down. Imported that into a NEW song, with only one audio track, and then proceeded to try to do an organ overdub...Well Logic still drops out and gives me the message, even though there is NO midi information in this file...
Then I noticed that even AIF or mp3 files, didn't play properly from the desktop preview mode. They stop too. Activity monitor doesn't seem to be showing anything overworking..
Disk Warrior fixed some volume errors,
Anyone have any ideas to try?

I'm using a motu828. I disconnected the firewire connection, and ran audio from the headphone jack to the motu, and VOILA, no problems... Last year, I went thru two motu units, not really sure if they are the issue.
I think it might be LOGIC's firewire circuitry. Apple techs couldn't find the issue, I had the G5 motherboard replaced. Another factor was I had 3 Lacie firewire drives (2 firewire 800, 1 400) I have had 4 Lacie drives die on me in the last 3 years. They are the only firewire drives I have, so I don't know if the fault lies with them, or the again Apples firewire circuitry, stressing the drives out???
I also put a firewire 800 card in my system.
I have now switched to an external ESATA raid setup. No more firewire drives. So far so good. Since I had the whole motherboard replaced, I don't know what that means in terms of MOTU connected via firewire..
For now, I'm running audio out of headphone jack, using all virtual instruments, so I know it will sound better when I get firewire audio up and running, but I got tired of it cutting out every 3 - 30 minutes. I'm thinking about the apogee duet unit. But again if it's connected via firewire, I don't know where that leaves me..
My G5 is three and half years old, perhaps it's tired and wants to be retired....
The dark part of me wonders, if Apple computers don't start crapping out after three years of heavy use, or is it that technology, software, updates, push the hardware beyond it's capacity after a few years.

Powerbook audio in/out: advice needed

I don't understand my 15" aluminum powerbook's audio in/out. I know that the input jack requires a far higher power signal than my nylon string Gibson solid body Chet Atkins CE guitar is able to generate, so I have to run the signal from my guitar through a pre-amp, to boost the signal high enough to allow it to lay a decent audio track into my favorite Macintosh sound editing program (www.felttip.com's Sound Studio.)
It's also vital to be able to simultaneously hear what I'm playing, while I record it. It seemed logical to assume I would be able to plug my Bose stereo headset into the headphone jack of my Powerbook and listen to what I'm playing while I'm laying the track down in Sound Studio...but the headphone jack is totally dead while I'm recording. However, after the recording is done, I can play the .aif back with Sound Studio (or, for that matter, with iTunes) and the headphones work great.
It appears that the Mac audio system is only able to do one thing at a time...either take in sound via the Input Jack, or output sound via the headphone jack....but not both, simultaneously. And it seems to me that having anything plugged into the input jack, deactivates the headphone jack.
Is this true, or am I doing something wrong....?

Without doubt the problem rests within the particular software you are using as the PB is indeed capable of "duplex" operation - i.e. it can output sound at the same time as it is recording.
Go into the preferences section of Sound Studio (not a programme I'm familiar with I have to say) and look for an item named "Playthrough" (or similar). Check this box and all should be well.
If you want to confirm that your PB does do record/play at the same time try downloading another audio programme (such as Amadeus) - when you hit the record button in that programme you can easily set the system for playthrough from the Settings area of the pop-up box.
Hopefully you'll manage to get things sorted out.

Problems with audio line out jack

When I connect the headphones in the audio line out inmediately change to "Digital out" and I don´t listen nothing, but when the headphones is unplugged I hear the music through the internal speakers normally. What can I do about? Thanks.

I need to change the logic board? or only the audio line out jack can be replace?

Audio cutting out

Hi, I am using Logic 7.2.3 on an Intel Mac with 2 gigs RAM. I am having a problem with audio cutting out both during playback and bounces. This occurs whether or not my Mackie Onyx 400F is switched on. I work with a lot of midi instruments, and the frequency of the audio cutting out does seem to increase when I have more instruments. Do I just need more RAM, or is there something else I should do to solve the problem?

Increase the IO Buffer size.

Audio Drop Out/Popping sound Problem

Hi,
For the last few weeks (since i installed snow leopard i think), i have been getting a lot of audio drop outs, where all of a sudden the sound goes dead and i get a popping sound coming from my speakers.
I am using a pre sonus fire studio project audio interface, with its firmware updated to the latest (the latest update was a beta snow leopard update).
I am running logic pro 8 with snow leopard 10.6.2.
I think i have narrowed the problem down to my presonus fire studio because i totally disconnected it and used logics built in audio soundcard and i didn't get any audio drop out at all.
I was just wondering if anyone had any similar experiences or ideas and suggestions on what is best to do?
thanks in advance for any help.
Tom

It depends, are you running off battery when this happens? If so then morethan likely it is the audio hardware coming back online. In an effort to conserve power, what Mac OS X does is when you are on battery is that it turns off your audio hardware when it has not been used for a certian amount of time. This popping sound is typical of the audio hardware being powered up.

Midi Audio Cuts out when Playback tracks are triggered.

Hi,
I am having an issue where if I open Mainstage 2 and begin playing a Midi Sequence through a 3rd party Plug-in, the audio cuts out from the plug-in when I trigger my group of Playback tracks for the first time and only restarts when a new note is played. This is particularly a problem because the sound is arpegiated and continuous. 9 out of 10 times if I do it again right afterwards it will be fine without any issues at all. There was a time during rehearsal when it absolutely would not work, but I think a restart fixed it. CPU usage and memory usage do not seem to be the problem.
So my question is, is it normal for it to do that on the first time? Is there any reason why it would not absolutely work that time during rehearsal. And lastly, is there anyway to make it just work every time!
I have tried reading up on this, and from what I understand, putting each playback track on a separate patch might help. My issue with that is I have already designed a layout that fits everything on one screen in one patch. I don't want to be switching screens during a song to adjust levels for the playback tracks. I have One Vocal, One Midi Synth, 8 playback tracks, and 3 Aux strips.
I am new to mainstage and might not completely understand how to make a set work with patches, but from what I understand if I put the playback tracks on different patches I can't control everything from one screen.
Any thoughts, insights, or advice is greatly appreciated.

Logic has that issue at times as well- where the first notes of a midi passage may not play. I believe the timing is such that the note starts are actually slightly before the first beat. Check your starting notes to make sure that they are really starting on the first beat and not slightly before.

Audio cutting out when using D2 external Firewire Drive

Hi,
I have just upgraded to Logic Studio, using the following setup:
Macbook Pro
Motu 828
AMT 8
Logic Studio
D2 Lacie 500GB Firewire Drive
As the MacBook's internal hard drive is not sufficient to record and playpack efficiently, I was advised to get an external Firewire Drive. Given that I have very little space on my laptop - (am running windows on a partition also) I am trying to save my logic files to the external HD. When creating tracks specifically using Audio Instruments, the playpack keeps cutting out.
I am connecting the HD via usb 2. I am also having to freeze the tracks in order to record more layers. There is lots of clipping and latency. I thought by using the external, this problem would be resolved.
The HD is not playing back the tracks fast enough, and keeps cutting the audio out. The audio cuts out everytime the blue light on the drive flashes.
I cannot save the files to the MackBook HD as there is notenough space.
Is there something very wrong with my setup?
any advice would be really appreciated.
ps. I am a bit of a newbie
thank you in advance.

Connect it via firewire 800. USB2 is not good for audio or video streaming.
I have 3 D2's connected to my mac pro, works like a charm.
good luck.

Logic 9 Audio and Video sync at beginning timecode, but not in the middle of playback.

Hey Guys,
I'm working on a Trailer for a feature length, and my video playback is pretty screwy.
I've double checked the video to be 23.976 framrat and set my project to that framrate, and I've done what I normally do with bitrate and sample rate. But currently my audio and video will not sync together when I start playback in the middle of my project.
Playback works fine in the start of the project, and everything looks and sounds great. But as I'm writing and edtiting further on in the project all the audio gets out of sync. If I start the project from the beginning, then all of the MIDI for the whole piece registers as synced, and the project sounds and looks great the whole way through. The problem comes from starting playback anywhere in the middle of the project.
I'm working with a .mov file (1:45 minutes); three .AAC audio files, and plenty of thrid-party plug-ins. 10.7.5 Mac OS X, 2.2 GHz i7 core, and 4GB m
of memory.
Any thoughts?
Thank you!

Thanks guys for the input.
I am using an Aurora 16 via firewire
I did change my buffer settings and that seemed to fix it but now I am at 128. I moved over to the aurora because I preferred the extra headroom. I guess I should have stuck with the apogee.
Tonight was the first time I had the opportunity to do a full tracking session with 9. I have been doing quiet a bit of mastering with no issues. Quiet a few issues. Everything from logic quitting to it just locking up. So far.....a pretty bad experience. I wonder if it could be Snow Leopard.......

Damaged Audio line out jack

Hope to get some advice here - after messing with my MDD to get a Time Capsule up and running (while changing the ethernet connections a couple of times), I managed to thwack the audio line out cord from the box enough to damage it - I noticed one channel of the audio was gone, then after finding the jack is loose, wiggled it just enough to make it worse or better depending where the cord sits... I am using powered speakers so the apple speaker mini-jack doesn't seem to be a good option instead of the line out...
The question is, can this be repaired without replacing the logic board?
Many thanks in advance!
David

Hi, David -
Repairing that component could be not inexpensive (if done by a tech shop) or risky (if done by someone else).
As an alternative, you could consider using the Griffin iMic Adapter.

Soundcard not registering [Cirrus Logic HD Audio]

Maybe this has been said before, but I'm running the bootcamp (3.1).
I haven't seen any improvements to the driver for the soundcard.
I run two different media recording programs on my mac, but the XP side won't
recognize the soundcard (most programs enable use of recording directly from the sound card itself) on any of the programs (I've tried several different programs leading to the same outcome), it only registers the microphone.
Has anyone encountered this problem as well?
I know there's a fix posted for the realtek drivers, but the cirrus drivers still have the problem.

It's October 9th, 2010... and I can't find a solution for this. I'm using Bootcamp: Windows XP SP3. My mic works -- only playback is stuck at like 2 or 3 times slower than the regular speed. I don't know how to fix this manually and my assumption is that I need a driver. Playback voice sounds like an alien in programs I use for gaming such as "Ventrilo" -- If there is any help out there -- I could use it.
Cirrus Logic HD Audio not playing back at normal speed. Records fine. Just nobody can understand me if I talk to them via my mic.

Logic playback is cutting out

I bought a new iMac 756GB flashdrive and 24GB RAM. I migrated from my older iMac to my new one. Now on play back, in Logic, I keep getting audio cut-out as I play through my projects. It cuts out at random. I have checked that it does it in both audio interface mode (saffire pro \; thunderbolt to firewire) and in standalone with it's internal audio i/o). Is any one else experiencing these problems?

Problem solved - I had to authorize iZotope.

HELP! Audio Drops Out When Trying to Capture Canon XL2 Footage

Please help me out here. I'm a freelance camera operator w/ a Canon XL2 and several times now I've gotten calls from the editors saying they're having problems logging my footage, mainly the audio drops out quite a bit, and I'm not talking bout one second for every 2 or 3 minutes. No. It's like every 10 seconds the audio drops in and out.
What's the deal? Two times the guy was using a Panasonic DVX-100A to capture, another time it was a SONY DSR mini-DV deck. With each incident I had to go over with my XL2 and use it as the capture device, which is a pain.
The program they're using is FCP HD or 5. But I think even when they just play the tape in their Sony or Pany cameras, the audio may still suck.
Help me out here, I can't be the only one with this problem.
Thanks.

Well Robert Swanson, I hope my post wasn't taken offensively, it certainly wasn't meant as such. The only Canon camcorder I owned was the GL1. After switching to Sony's I can honestly say it would take something significant to go back. And, I was merely relating my experiences in trying to capture from other Canon camcorders so that I know where you are coming from. However, I am interested in the HVX being the "noisest" camera on the market. I am seriously considering this camera and would be interested in a review that points this out. I would be using the hard drive recorder instead of P2 cards.

I havent any vocal loops on logic pro. its greyed out. How do i access this?
