Bug Description

i have no 5.1 surround sound,i have also google this heaps and also tried many of the fixes with no luck.also i have had this problem before and have been able to fix by changing a few lines in /etc/pulse/daemon.conf but i now have a new gigabyte m/b model h61ma-d2v,also i have been using linux for about 5 years but i ended up in desperation loading xp pro to another hardrive to see if i could get 5.1 surround to ensure both speakers and m/board were not faulty and it worked fine..any help would be much appreciated

you need to switch channel mode from 2ch to 6ch and restore this setting by alsactl before pulseaudio start

the channel mode switch from 2ch to 4ch or 6ch , retask the blue and/or pink jacks at rear panel as output jack

the driver should also change the state of rear mic jack and line jack to false

amixer -c0 set "Channel Mode" "6ch"

alsactl store

restart pulseaudio server

Realtek codecs --------------

* Channel Mode This is an enum control to change the surround-channel setup, appears only when the surround channels are available. It gives the number of channels to be used, "2ch", "4ch", "6ch", and "8ch". According to the configuration, this also controls the jack-retasking of multi-I/O jacks.

can you post the pulseaudio log ?

I don't understand how can pulseaudio server switch to active profile surround51 when blue and pink jacks had not been retasked as output ( Pin-ctls are still IN ) and channel mode is still 2ch.

after switching to 6 channel node. analog-input rear mic and line-in ports should be unavailable

http://www.intel.com/support/motherboards/desktop/sb/cs-020642.htm#6ch

Jack retasking is a feature that allows an audio jack to support more than one function. For example, the pink audio jack can support microphone input when the system configuration is set to Stereo Mode, and as Center/LFE or Rear Surround (depending on the audio solution used) when set as 6 channel.
