Please describe the problem:
When recording and playing back audio at the same, there seem to be some terrible problems where the audio at the beginning of the playback audio is very jittery and broken. Wim suspects it could be caps negotiation problems thrashing it.

This problem manifests in Jokosher. This is what I do:

  import audio into a track
  play audio
  stop
  add second track, select the input and record
  (hear broken audio for a few seconds and then stablises)
  play all audio
  add new instrument, select input and record
  (very broken, skippy audio again at the beginning)
  press play, loooong delay before audio plays
  play again

I have attached a debug log when running the above steps.

Steps to reproduce:
1. 
2.
