Link to original thread & what does MediaInfo say about the media specs would help those of us new to this conversation.
Vaguely guessing, try transcoding to an Mezzanine format (ProRes/Cineform) for easier playback.
If you "mute" all your video tracks does the audio still drop out?
Have you checked your ASIO buffer settings in the audio hardware preference?
I had an issue with my sound being completely distorded because the buffer was at 1024 and apparently, my device needed it to be at 512.
That could be it.
Latency was set to 200 ms when I conducted this experiment. The available range is 30 - 500 ms. I tried a couple of other values (30, 500) based on your response, and the problem showed no improvement.
I recommend using Cineform proxies for all H.264 media.
Additionally, I recommend a dedicated Cache & Scratch disk. Try to keep everything off of C: except Windows and Prorgams
That solved it - thank you Jim.
