Hi Matthew,
just back from a holiday trip, so a bit late reply. But let's see...

It would seem that the SD disk you are writing to is not fast enough to
write data as it is recorder from /dev/dsp, or that ecasound is spending
too much time in passing buffers in the engine. Could you try:
1) Make a quick test recording to a ram-based filesystem (/tmp or
some tmpfs partition)...? The recording cannot be too long
anyways, but you can check whether it's the SD writing, or
something else.
2) Record with:
sh> ecasound -i /dev/dsp -o test.wav -z:nodb -z:intbuf
I.e. skip the double-buffering when writing to the SD card.
