I had similar sound quality problems on my FreeBSD Asterisk until I
did the following:

        - Added the INTR_FAST flag to the bus_setup_intr() call in
          wcfxs.c (zaptel).  (Might not be the best/final solution,
          but it works for me.)

        - Started Asterisk on rtprio 0.  If you do this, you should
          probably also modify the source so that Astrisk lowers its
          priority to normal after forking.  There are unfinished
          patches for this on bugs.digium.com.
