There is also an OSS driver, and SDL/Pygame supports esd and arts output. No
promises wrt. latency or flexibility with these implementations.
I tried the python/alsa stuff but concluded that it was not ready for serious
use. The full duplex example actually uses C to run in a background thread,
i.e.
the python integration is a loose coupling. Also IIRC in output-only it does
not need this background thread, but does not work with more than 2 channels.
Following that I attempted to create a jack client for python. The problem
with that was python did not seem friendly to the idea giving up control
of execution to jack... so again at best it would probably be a loose
coupling using a background thread.

In the end there is really no good substitution for C/C++ when it comes to
realtime audio, but there is nothing wrong with doing a not-quite realtime
interface or some sound analysis in python.
