Title:
  [VGN-A690, Realtek ALC260] No sound at all internal speakers and
  headphone (Green out)

Status in alsa-driver package in Ubuntu:
  Incomplete

Bug description:
  I have tried using different options in /etc/modprobe.d/alsa-
  base.conf. Without probe_mask=1 it also detects a Conexant modem.

  I just discovered there is sound output from the rear A/V Out port of
  the laptop, but there is popping whether or not audio is playing.
