I have a ION 330 ASRock just updated on Precise and the sound channel mapping is incorrect.

Channel map is set as follow:

Front Left = Front left 
Center = Rear Left 
Front Right = Font Right 
Rear Right = LFE 
Rear Left = Center 
LFE = Rear Right

I am testing the sound channel using

speaker-test -c 2 -t wav

Can some one tell me how I can remap easily?

I have tried several possible changes to /etc/pulse/defaut.pa unsuccessfully.

I have an ASRock ION 330 with 12.04 LTS.

I'm not engineer, so may this maybe incorrect, but channel map works perfectly in my ASRock ION 330.

If you output sound on HDMI, open extra-hdmi.conf by running this in the terminal:

gksu gedit /usr/share/pulseaudio/alsa-mixer/profile-sets/extra-hdmi.conf

edit

[Mapping hdmi-surround]
...
channel-map = front-left,front-right,rear-left,rear-right,front-center,lfe
...

to

[Mapping hdmi-surround]
...
channel-map = front-left,front-right,front-center,lfe,rear-left,rear-right
...

and edit [Mapping hdmi-surround-extra1], [Mapping hdmi-surround-extra2], [Mapping hdmi-surround-extra] in the same way.

Save the file, then run

pulseaudio -k

to apply the changes.

In Sound configuration, choose "Digital Surround 5.1 (HDMI)".
