Hi. My drives are local, direct attached storage. See my signature for hardware: SCSI RAID, 1-1.5 MB/s io according to BM Disk Speed Test. I have my audio playback buffer set to the max, 4096*, the optimal setting to reduce playback issues. I have a truck load of RAM, and a very powerful MacPro. There should be no bottlenecks in my io.
Note that I exported a .wav file only, and it contained the same dropout. An audio only export would have reduced the load on the CPU & GPU to very little.
I was unaware of the Render Speed option under File, Reynaud. I'm not new to NLEs, but I am new to Resolve, and most of my hiccups transitioning from Premiere have been about settings and terms that are so different. A trip to the manual reveals that Render Speed is primarily intended to address network bottlenecks.
But, I tried a test at a Render Speed setting of 50, and the export I made had no audio dropouts. So, thanks a bunch for the tip! Now, I know it's there for the next job.
* The conventional wisdom is that high playback buffer settings reduce clicks and pops and CPU overload in audio playback and rendering (I've been doing music production on DAWs for decades.). I was experiencing dropouts in just playing Timelines in Resolve (with Color effects off), and was starting to think that something's wrong with Resolve. But, I just now reduced the buffer to 2048, and now my audio is playing far better. It seems counterintuitive, but hey, it's an improvement.
