After the render, it played with black holes and areas where audio motorboated. Deleting cache files wasn't the fix. Rolling back to 313.58 was.
However, with 313.58, a partial render (of a selected segment) also hosed the archival file in similar fashion, auto-rendering portions of the file when played, and then refusing to play the result without the problems mentioned above. In that case, deletion of cache files and reloading of the project restored it.
The latest driver isn't always the best, though they are said to be backward compatible.
Just conjecture, but perhaps a characteristic of the "latest" driver trips up PD, as opposed to features of the driver that was then the latest at the time the program (or most recent patch) was released.
