Audio dropping out during playback in timeline

Hey everyone,


I've dug through these forums and unless I just completely overlooked it I have not found a solution to this issue. I've listed my setup below and then have stated the issue I'm experiencing.


27-inch, Mid 2011 iMac

3.4 GHz Intel Core i7

16GB 1333 MHz DDR3

AMD Radeon HD 6970 1024MB

Running Mac OS X Lion 10.7.5 (11G63)


Currently working off of a portable 1TB G-Technology G-DRIVE via FW800.

Working in Premiere Pro CS6 Version 6.0.2

Editing in a sequence with settings:

1920 x 1080 23.976fps (also tried in a 29.97fps timeline with same issue)

Working with footage that is 23.98fps

Working with a combination of ProRes 422 (LT) and native H.264 Quicktime files strait from a 5D Mark 3.



The issue I'm having is during playback the audio will competely drop out. The video will continue playing on just fine but the audio drops completely out. All audio levels drop as well in the audio mixer meters so it truly is losing all communication with my audio layers in the timeline.


I read in other forums to go into Finder and delete out the .caf files, re open Premiere Pro, wait for them to be recreated then carry on. I tried this approach with no luck. Deleting the .caf did not change anything. Audio is still dropping out as I try to play through my timeline. The only way to get the audio back is to pause then press play again. I have 5 total channels of audio with only 2 of those channel active.


Any ideas on what is happening would be greatly appreciated. This is incredibly frustrating have to export out a video just to be able to watch it through.

    I had the exact same problem when transitioning from FCP to Premiere the other month. It was indeed incredibly frustrating. I solved it in my instance by keeping my projects and cache on the system drive (Documents/Adobe/Premiere Pro/6.0 on a Mac). Haven't had the audio dropouts since. I'm guessing it might be a similar problem for you as you're working off an external drive. Try keeping the media and assets on the external drive but the project on the system drive in the Adobe default location. Good luck!

    Go figure! The glitch drove us crazy until we worked it out. Our workflow with FCP in the past relied on all the media, projects, renders, etc being stored on shared network drives as jobs bounce around suites a lot. We still keep the bulk of the assets on the network drives and at the end of each day dump our project files down to them as well in case another editor needs to pick them up. They just copy the project file into their Documents/Adobe/.. folder and away they go. To date we've had no further glitches, touch wood.

    I also have been struggling with this issue with the exact setup as JordanLynn above (iMac 27", etc.). The only difference is that my FW800 is a permanent RAID5 storage device.


    I searched high and low for info and posted on CreativeCow: and spent hours on the phone with Adobe.


    I will post this as a solution back on CreativeCow and try it myself.

    Bugger. My last ditch piece of advice would be to create a new project (on your system drive, keeping the associated cache files in the same hierarchy) and then import your existing project into that. I tried that early on and it seemed to resolve one problem project, but no guarantee it'll fix your issue. Is anyone else accessing your media or files on any other machines? We've found issues with simultaneously accessing shared media.

    Getting this same problems in Premiere 7.2.1.


    Suddenly my sequence's audio drops out entirely. The waveforms are there. Video plays back at the full frame rate. But no audio.


    I'm working on a 2012 Mac, 24GB RAM, OS 10.9.1, with Prores LT files in a Prores sequence, 29.97. No mixed frame rates. Previews and caches are stored locally on the startup drive.


    All I can do is to duplicate my sequence periodically, and then I revert to my last saved version when this occurs. This is obviously not ideal.
