The funny thing about Bill's predicament is that I don't know of
any test program in Linux that exercises simultaneous audio input
and output -- if Pd fails, I don't know how to set about deciding whether
it's a problem with Pd or with OSS (or Alsa or whatnot.)  I'm using 
Pd0.28TEST6 right now and enjoying full duplex, for what that's worth...
(available for Linux only so far, from www.crca.ucsd.edu/~msp/Software)
