I have a Behringer UCA-202 attached to a BBB running Ubuntu. It's
running a csound score that implements a variable delay line. Audio is
48kHz stereo 16bit via ALSA, not sure what the latency is exactly but
it's small.

The PRUSS is very interesting for high speed hardware interfacing, but
it seems difficult to integrate with linux, you would need to write
kernel drivers to work with ALSA or JACK. Connecting DACs and ADCs using
I2C or SPI could work but how to synchronize with the audio system?
