I believe he still uses isochronous, only with async endpoint to adjust source rate, so PLL still needed to lock on bus. Plenty of ways for jitter from the PLL clocks to get to the audio clock circuits, even when the sample clock is derived from a local oscillator. No huge surprise there. Still looks like a nice, simple design though.
