[Bug 1457476] Re: Realtek ALC887-VD speakers don't mute when headphones are inserted


Thanks Raymond, this is very useful. Just to make sure I understood
correctly: the front panel jack detection was turned off for my
motherboard by the patch you mentioned in comment 17, because it was
causing problems for some users.

So, we'd need a way to revert it, but only for those boards actually
having the ALC887-VD codec.

Is my understanding correct?

  Realtek ALC887-VD speakers don't mute when headphones are inserted

Status in linux package in Ubuntu:

Bug description:
  I Have a Gigabyte GA 970a-DS3P motherboard with integrated audio
  chipset, which alsamixer reports to be an ALC887-VD.

  I uploaded the results of the ALSA script here:

  I have a line out connector on the back of the motherboard (along with
  line in and mic), and a headphones and a mic connector on the front of
  the PC.

  The problem is that when I plug in my headphones, the speakers (connected via the back connector) continue to play as well.
  Also, I haven't found yet a way to set the volume independently for the headphones and the speakers via the Gnome/Unity sound settings. I can only do that via alsamixer, where the "Headphone" control refers to the headphones, and "Front" to the speakers.
