Thanks you Clemens for clearing that up. How would one go about
determining the size of this queue between ALSA and USB?

And is it correct to assume that in a best-case scenario where the
sample clock is synchronised to the USB clock and the period size
coincides with the interval at which USB frames are signalled, the
additional latency will be one period?

Cheers, Tim
