"Chipmunks" sound implies that the audio is being played back at a
higher sample rate than it was recorded at. Obviously this should not
happen if all layers are aware of the recording sample rate and adjust
playback accordingly. So you would need to find out what part of the
system is using (or guessing) the wrong sample rate.

It could even be that the problem is right at the end -- if pulseaudio
is outputting 44100Hz and the hardware for some reason is playing at
48000Hz. Perhaps even a hardware fault if not software. You would need
to establish at what point the wrong sample rate or conversion has been
chosen. Sorry I don't know the commands for that...

  Sound Chipmunks on playback with Jabra Evolve 65 UC Headset

Status in pulseaudio package in Ubuntu:
Status in pulseaudio package in Fedora:

Bug description:
  Whenever I choose the Jabra Evolve 65 UC Headset as the playback
  device, there are sound chipmunks. The same was the case with Jabra
  Motion Headset as well. But those two headsets worked perfectly in
  Windows, Mac OS and Android.

  There was a workaround mentioned in
  https://bugzilla.redhat.com/show_bug.cgi?id=1282285 by editing the
  contents of /etc/pulseaudio/daemon.conf :





  and then running

       pulseaudio -k

  made the sound on Jabra good (no more chipmunks). Also, when I opened
  the Sound Settings with the changes in daemon.conf in place, there
  seems to be some distortions in headset sound, which goes away few
  seconds after I close the sound settings window.

  This problem should be fixed, as many new Linux users will find it
  difficult to edit files requiring root access, and those who do not
  use command line won't be okay with it.
