Fixed by "Turning off PulseAudio timer scheduling" from https://wiki.ubuntu.com/Audio/PositionReporting .

[Launchpad Janitor (janitor)]

Status changed to 'Confirmed' because the bug affects multiple users.

[Raymond (superquad-vortex2)]

Default sink name: alsa_output.pci-0000_01_00.1.hdmi-stereo
Default source name: alsa_input.pci-0000_00_04.0.analog-stereo
