When I tried this, I needed "rate 44100" ... the re-sampling would make aplay use a lot of CPU time. Also, I don't know if there's a transcription error, but "buffer_size 6553" looks like a typo -- it's not a power of two, but 65536 is of course.
Thanks, I made both of your suggested changes and it reduced CPU usage down to 20% per aplay process... but that still seems like too much! Is this normal?

Seems high to me. I'm just using alsaplayer and it all seems to be jsut a few percent...
