How to make subwoofer work in Ubuntu

Using the same computer with Windows 8 and Ubuntu I noticed that the sound was worse in Ubuntu and I discovered why soon: subwoofer doesn’t work out of the box!

How to fix it

The fix is quite easy to apply (but it was not easy to find the right one!). First of all edit /etc/pulse/default.pa and add this line at the end:

load-module module-combine channels=6 channel_map=front-left,front-right,rear-left,rear-right,front-center,lfe

then edit /etc/pulse/daemon.conf, modify the line “enable-lfe-remixing: no” to “enable-lfe-remixing: yes“, then uncomment it (remove the semicolon in front of it). Reboot your PC and enjoy the subwoofer!

  1. Hello Andrea,

    thank you soooo much! This did the trick for me and i finally managed to bring my subwoofer back to life!

    My Creative USB 5.1 Sound-Card worked well, but the subwoofer has always been a problem. Now, after more than 2 years this problem is solved for me.

    Thanks!
