Public bug reported:

(alsa-hdspe-dkms)

On new (2021 refresh model) RME RayDAT.

repro steps:

play a youtube video or other web stream. open in a new tab:
https://solitaired.com/spider-solitaire-four-suits?difficulty=medium.
drag a card and you’ll see the audio breaks into a buffer loop.
hdspeconf (snd-hdspe’s partner app) shows rapid flipping between
samplerates and pw-top shows xruns escalating.

next, Bitwig using snd-hdspe via ALSA. broken sample rate and buffer
selectors. engine will only start at 48k/256 but any polyphonic playback
suffers bad sample/bit rate distortion.  (Unsure if this is driver or
bitwig's alsa implementation because Ardour seems better under ALSA and
can adjust rate & buffers properly).

These issues occur under various conditions when using the RayDAT
interface but the above are 100% reproducible examples.  Same behavior
in multiple Linux distros.
