So I recompiled 'alsaplayer'.  It still works on all the
things it used to work on, and it now loads all the soundfiles
from 'timemachine' and appears to be playing them.  But
what I get is silence.  I don't get it.  Timemachine's little
meter is bouncing away in sync with the input, which implies
that it's getting a signal.  So what I see so far is that one
of three things could be happening:

A) 'timemachine' is not really recording properly but writing
     the file correctly
B) 'timemachine' is recording okay, but not writing the file
     correctly.
C) 'alsaplayer' isn't reading/interpreting the file correctly.

Anybody got any good guesses on what to check next?

Thanks for any input,
~Jos~
