Get rid of the pops:
- interrupt is called when the block has been DMA'd... since LASI seems to
include a FIFO this is -not- the same as block completion which we have
to poll for. Luckily the FIFO is deep enough that polling in the
interrupt handler seems to work.
- This probably breaks capture, but I'll fix that when I get up tomorrow.
(committed to the tune of Fugazi's "Waiting Room")
