Echo cancellation is a very cpu-intensive process (even on my Core i5)
that also involves floating-point operations. I think that omap4 is just
not powerful enough to do echo cancellation in software, and I guess
that's why your pulseaudio deamon is getting killed for running over the
CPU time limit.
Could you try to verify this theory by uncommenting the "cpu-limit = no"
line in daemon.conf? This will lock up your omap4 board, though, if I
guessed the reason correctly.
