Title:
  [IdeaPad Z470, Realtek ALC269VB, Speaker, Internal] computer freezes
  when setting volume

Status in “systemd” package in Ubuntu:
  In Progress

Bug description:
  when i press the volume slider the volume gets stuck on maximum then
  returns to mute.. by then the window freezes and i cant use the
  keyboard to type anything.. the task bar doesnt respond to anything
  and so i have to restart my pc again.. only way to set the volume
  without having this issue is to go to settings and adjust the volume
  from there.. pretty frustrating though..
