Title:
  [Brazos, Conexant CX20590, Speaker, Internal] volume slider problem,
  Fn+arrows control

Status in alsa-driver package in Ubuntu:
  Incomplete

Bug description:
  while using Fn+right/left arrows to control the sound volume on the
  internal analog speakers output, the pop-up shows with its value bar
  growing or reducing, accordingly, but no actual volume change is
  performed, unless it is changed using the pop-up slider bar from the
  system tray speaker icon. however, the brightness control using
  Fn+up/down arrow keys works properly; the problem might be in the
  presently active sound system, which is alsa, afaik. other sound
  systems like oss or pulseaudio not tested yet as system default.
