I am having the exact same issue but it is related to my DeckLink card outputting sound and video to HDMI. There seems to be no way to only send picture and not both as I think Resolve trying to sync the two sound devices is what's causing my stuttering
We will need more details. I'll give you an example of the number of factors we consider when trying to isolate what's responsible for a typical audio issue...
On which page? Is it isolated to one project? or does it happen on all projects?
Do you have any Desktop video devices? any auxiliary audio hardware? is the speaker selection automatic? Could you give more information on your speakers and drivers? Does the same project with the same files work on another machine / another OS?
What audio format are you playing? Does it work in the source player? Does it cause issues in the timeline?
How complex is your project? Audio FX? number of tracks? Does it happen on a simple timeline with single wav file?
These issues happened to all projects. I had to re-install the newest focusrite driver that was already installed for my 2i4 Scarlett 2nd gen to solve these problems. So everything is working again for me.
