Premiere Pro CS6 odd Audio Dropouts
I have a ProRes sequence with 14 tracks of audio & 4 sub mixes going to a multichannel output. The source clips are generally multichannel (up to 8 channels max), and on the timeline, I select which channels from each clip that I want exposed (ctrl click Audio Channels), so at most, each track of audio is only two channels (standard tracks).
The problem I am having is that when playing the project, sound will drop out, sometimes mid-clip, sometimes at the start of a clip when it hits volume keyframes. If I stop the playhead, back it up a bit and hit play, it plays ok (i.e. the sound it wasn’t playing before), then after a while, dropouts occurs.
When monitoring the Adobe Audio mixer when this happens, the audio tracks go completely dead, nothing registered on the VU meters, so I know its something before the sound card itself.
This is extremely frustrating, as I am trying to do the sound mix. I have read about deleting media cache files, .cfa etc, but to no avail. If I render in place, then the audio plays fine.
So does premiere have an issue reading audio streams from multichannel files or is this a performance type problem? My media is on an external FW800 drive. Would moving it an internal SATA make a difference ?
I did originally have all the external WAV files and Prores MOVs in the project and created merged clips (which are unwieldy on the timeline). I put these into separate sequences for each clips and then cut these ‘clip’ sequences on the timeline. From a performance point of view, I had no issues, but working with media in this way is time consuming and brings it’s own problems (like having to keep delving into the nested clip sequences and selecting which channels are needed, CTI not matching up when you drill down, waveforms not present on main timeline easily etc etc), hence why I decided to create new versions of the MOV files with multichannel audio embedded.

I honestly believe it’s a Premiere problem, I’ve seen this happen for many years. Not often enough to bother me, but it does happen once in a while. Restarting seems to clear the issue.

I moved all my media to an internal drive and this improved things, but it still drops out occasionally using multichannel audio files. Using the separate audio files doesn’t seem to result in drop outs.
It would be nice if PP had a performance meter (such as can be found in Cubase), that shows you whether its struggling.
