4.1 speaker is not working in ubuntu


Hi all,
I am using ubuntu for last three months, i have 4.1 speaker only front speakers are working rear speakers are not working.(Rear speakers are working fine in Windows) I googled and made following changes

sudo gedit /etc/pulse/daemon.conf

default-sample-channels=2 in daemon.conf

i changed it into default-sample-channels=5

But still my rear speakers are not working, could anyone help me in enabling the rear speaker.

My sound card details

Front and subwoofer, LFE, are default in alsa. You can change the default using the ~/.asoundrc file.

You could have stereo out of all speakers or genuine 4.1 if that was what was being provided by the sound source as it were.

The alsa wiki is the place to look, it is not as friendly as it might be.
