Sorround 5.1 7.1

 

 

Enabling Surround Sound in libraries

By default, Ubuntu uses PulseAudio for its sound. Also by default, PulseAudio is set to 2 channels only. Enabling surround sound involves changing one line in the configuration file /etc/pulse/daemon.conf.

In the terminal, type the following:

gksu gedit /etc/pulse/daemon.conf

This should open up the configuration file in gedit. Once open, scroll down to find the line ; default-sample-channels = 2. Remove the semicolon at the start of the line and change the line according to your surround sound configuration:

• For 2.0 channel sound: default-sample-channels = 2
• For 4.0 channel sound: default-sample-channels = 4
• For 5.0 channel sound: default-sample-channels = 5
• For 5.1 channel sound: default-sample-channels = 6
• For 7.1 channel sound: default-sample-channels = 8

Save the file the restart your computer.

ALSA

Surround may already be working, make sure alsamixer has the right volume settings (Wave Surround in particular). These commands should be useful for testing:

For 4.0 surround (two speakers in front, two in the back):

speaker-test -Dplug:surround40 -c4 -l1 -twav

For 5.1:

speaker-test -Dplug:surround51 -c6 -l1 -twav

For 7.1:

speaker-test -Dplug:surround71 -c8 -l1 -twav

If it's not working, you might try following alsa's own guide:
