Some further looking has uncovered some strange behavior on the record side.
When I use

arecord -d5 -fS8 -r8000 -traw test.raw

and then look at the data and clock lines, I see that the pcm is not
functioning as designed. aplay works as advertised.

The frame sync line is at ground before the record, during the record it
cycles between 3.3 and 2.8 V with a rough square pattern at the bitclock
rate of 256k. Not sure if this is hw or sw...will continue to invesigate.
