Beta 3 Intermittent Sound

After working on a project for awhile the sound dropped out in the Timeline View. It still worked on the media page previewing clips but in the Timeline still no sound EXCEPT if I grab a clip end. The sound will play for 1/2 second then cut out. If I move a handle again, sound for 1/2 second again then out. Quitting Resolve and restarting fixes this but I haven't kept working long enough on the current project to see if it goes out again. I have noticed this on another project after working for some time. Same System as I had 14 on and this never occurred.
