** Description changed:

  This is a bug on Ubuntu 20.04 (Focal Fossa) for pulseaudio version:
  1:13.99.1-1ubuntu3.2.
  
  Description:
  
  At random intervals, pulseaudio gives the following error message:
  "snd_pcm_avail() returned a value that is exceptionally large: 125388
  bytes (710 ms)," after which the system slows down to a crawl. It has
  occurred in two instances: while playing a video game, and while working
  in two different workspaces with a zoom client and Spotify open (though
  not actively playing any audio). The system is recoverable with the
  SysRq key. I have not been able to duplicate it on command, but it is
  recurrent.
