You should be aware of these questions:
1) is your computer fast enough to handle real-time?
2) is the buffer length ('-b' flag) set to a sufficient dimension (at
least 500 when using in and out simultaneously)?
3) is the number of buffers ('-p' flag) big enough (at least 4)?
5) are you using a 'rounded' sr (for example 40000 Hz or 32000 Hz with
'-e' flag)?
6) are you using a Sound Blaster (the soundBlasters wave-in resolution
is reduced to 8-bit  when using full-duplex, but these cards are the
only I successfully tested. I have two soundblaster in my computer to
avoid the 8-bit problem).

good luck!
