Title:
  [HP Pavilion dv7 Notebook PC, IDT 92HD81B1X5, Black Headphone Out,
  Front] No sound at all

Status in alsa-driver package in Ubuntu:
  Confirmed

Bug description:
  I suspended my dv7, when I tried to resume it crashed, I rebooted it.
  Since then, audio is not working, everything seems fine visually, I
  have tried many tutorials to no avail, everything seems to be in
  working order, but no sound comes out of speakers or headphone.

  I have also tried an external usb audio driver, no sound comes out of
  it either. It seems to be recognized, there is no indication that it
  should not be working.
