[linux-audio-user] csound5 lpc question

Hi!
  I'm trying to get some tests with lpc done with csound5. The problem I have 
is: my csound5 doesn't have it's own lpanal, so I used lpanal of 
csound4.23.something.
  it runs fine and outputs its analysis-frames. But when I run a simple test, 
it only outputs to cracks with a lot of silence in between.
  My orchestra looks something like:
  [header]
instr 1
  ktim line 0, p3, p3
  a1 buzz 15000, 110, 64, 1 ; function 1 is a sine GEN09
  krmsr, krmso, kerr, kcps lpread ktim, "voice.lpc"
  aout lpreson a1
  out aout
endin

  The audio-material, which I analysed was simple speech. Am I doing something 
wrong? Should I be sure to use one of lpanal's options to get good input for 
lpread/lpreson?
  Kindest regards
      Julien
