AFAIK there are no additional layers; they run at the same layer.
"ALSA" is ambiguous -- it tends to apply to either the kernel API, or
the API provided by alsa-utils depending on speaker and context ...
both solutions [PA, alsa-utils] still use the kernel API -- the
additional "layer" of emulating the alsa-utils userspace API would be
next to nothing (it wouldn't really be a "layer" per se, just some
extra calls internal to PA).

ime ... PA be rockin' :-)
