Title:
  [To be filled by O.E.M., Realtek ALC898, Blue Line In, Rear]
  Background noise or low volume

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

Bug description:
  Since I upgraded to 14.04 (actually, re-installed Ubuntu because I had
  new disks) sound in doesn't work at computer startup. I have to type
  "sudo pactl load-module module-loopback latency_msec=1" in order to
  get sound from my TV (blue audio plug). But then, there's a lot of
  crackle. I have to modify the input volume up and down, the output
  volume up and down, then the crackle has gone.

  I can probably put the module load in some startup script, but the
  crackle is annoying.
