If your surround sound is "virtualized" using only two speakers, this is a software feature and not a hardware feature that can just be enabled. Some applications could require a restart.įor 7.1 speakers and other configurations, the Arch Wiki has extensive PulseAudio documentation as well as dozens of examples.ĭisclaimer: This answer only applies if you actually have 5 true speakers and one true LFE (subwoofer). To enable the new settings, restart pulse with pulseaudio -k. Frequencies between 80Hz - 120Hz are generally recommended for the LFE crossover. Frequencies below this value will be sent to the LFE channel. You can replace 80 with the desired crossover frequency (in Hz).
Without the lfe-crossover-freq defined, it defaults to 0, which is not very helpful. (If you've altered these configs previously, copy from your backup of the original files): cp /etc/pulse/nf ~/.config/pulse/nfĬp /etc/pulse/default.pa ~/.config/pulse/default.paĪdd the following line to ~/.config/pulse/default.pa: load-module module-combine channels=6 channel_map=front-left,front-right,rear-left,rear-right,front-center,lfeĪdd (or uncomment) the following lines in ~/.config/pulse/nf: remixing-produce-lfe = yes If you have true 5.1 speakers, here's how you can configure pulse to take full advantage of all five of your speakers and your subwoofer:įrom etc/pulse/, copy nf and default.pa to your user's home folder.
See the "disclaimer" at the end of the post. This really depends on whether or not you have true 5.1 speakers.
