The first idea was occured by windows driver, because in my laptop supported dolby sound. So i found the interesting article to enable surrounding sound.
Before you changed the sound, first test your sound with command:
- For 4.0 surround (two speakers in front and back)
speaker-test -Dplug:surround40 -c4 -l1 -twav
- For 5.1:
speaker-test -Dplug:surround40 -c6 -l1 -twav
- For 7.1:
speaker-test -Dplug:surround40 -c8 -l1 -twav
Make sure, your application audio player or video player stopped. Because the speaker-test won’t work.
if working, now change the file in /etc/pulse/daemon.conf with your favorite editor like vim, jed or nano.
Then find the line like:
“ default-sample-channels = 2 ”
Because the default is 2, so change to you want. In here i change to channel 8, save then reboot your machine.
Hopefully work!!! Thanks
