"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... -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to pulseaudio in Ubuntu. https://bugs.launchpad.net/bugs/1710060 Title: Sound Chipmunks on playback with Jabra Evolve 65 UC Headset Status in pulseaudio package in Ubuntu: New Status in pulseaudio package in Fedora: Unknown 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 : Changing ;default-sample-rate=44100 to default-sample-rate=48000 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.
