it is an interesting way to get an alsa client to work. if it works out,
we should document it ourselves.

it's to use pthreads and the rtc to get finer control of packet timing.
it's a new feature.

it seems that the audio format isn't coming out right, but it's probably
because a2play is old.

are you running an old version of a2play? we haven't had to pipe the
encoder in the chain for a long time. run a2play with no options and if
it doesn't show -p as a valid option you need to get the current one
from cvs.
