Title:
  [P35V2, Realtek ALC282, Speaker, Internal] No sound at all after
  laptop suspended

Status in “alsa-driver” package in Ubuntu:
  Confirmed

Bug description:
  Speaker audio no longer works after suspend and resume on my laptop.
  The sound icon in the desktop sound settings does not appear muted and
  toggling the mute setting does not restore the speaker audio.
  *However* I can restore speaker audio by muting the audio and then
  increasing the audio volume from a muted state. This works when using
  the audio function keys on my laptop, I haven't tried achieving the
  same thing through the GUI. Strangely simply toggling mute doesn't
  restore speaker audio, neither does just fiddling with volume, I have
  to increase the volume from a muted state.

  Additionally headphone audio doesn't appear to have any problems, it
  continues to work after a suspend.
