Dolby (5.1) sound not working

[cincho]

Hello guys,

I have been trying for a long time (over a year) to get 5.1 sound on my laptop. My computer is a HP Pavilion Sleekbook 14, which is officially supporting Ubuntu (http://www.ubuntu.com/certification/har ... 206-11167/) and the sound card is a Intel 7 Series/C210 Series Chipset Family High Definition Audio Controller Audio.

I have read forums, blogs, wikis but it seems I can't find a solution for this, so sorry if you feel this has been already solved.

aplay -l:

Code: Select all

**** List of PLAYBACK Hardware Devices ****
card 0: PCH [HDA Intel PCH], device 0: 92HD99BXX Analog [92HD99BXX Analog]
  Subdevices: 1/1

lsmod |grep snd:

soundcore              13026  2 snd,snd_hda_codec

I have tried multiple things including the change to pulseaudio default-sample-channels = 6. And this is what I can see on Gnome Sound Manager, no 5:1 at all only stereo.



Any help would me much appreciated, thanks a lot.

Why not ask Ubuntu?

Sorry, not saying I'm using Ubuntu, I'm using Debian Jessie, just mentioning Ubuntu is officially supported to denote that there must be Linux drivers for it.

I have tried this solution already, it seems to pick the configuration on load, but when I try to select it on the dropdown it disappears.
