as far as I understood your experiment, you compared these two setups to
conclude "QARecord is to blame":

  1) noise -> jackmix -> QARecord -> wav-file
  2) noise -> Ardour -> wav-file

For mathematical reasons I would like to get your result from this
alternative setup (also giving better access to a root cause):

  3) noise -> jackmix -> Ardour -> wav-file

Some other interesting information would be, what program versions
(jackmix, QARecord) are you using?

Guido
