Core Audio requires frequent resets

A recent problem has emerged on my M1 Max Studio (up to date Sonoma) in which no media plays back after longer sleep periods. Happens in all apps - Safari ( Youtube) VLC Handbrake, Izotope RX, Premiere, Reaper … you get the idea. Timeline cursor doesn’t move on spacebar or via “play” buttons.

“Ask Siri” is off.

While the terminal command “killall coreaudiod” fixes the problem quickly, it’s an annoyance and I’d prefer to find the cause. I suspect it may be related to speech recognition within any one of several apps, but I don’t know how to sift through logs or even what to look for and how to be efficient about it.

I look forward to your suggestions.
