It's not clear to me that any of the challenges the article addresses could be improved by the use of a clock synchronization protocol, such as PTP - it is not within the gift of application software to modify the audio sample rate clock, nor the display refresh rate.

Beyond what the article discusses, I can imagine long-running audio applications where it might be useful to build an estimate of the rate at which the system time drifts relative to the sample rate clock. Even so, we're still in the realm of the application software having to take these slightly divergent timing sources as given.

Or just have a way for a chipset to expose it's clock instead of all the methods people use to guess using buffer fullness.
