5.1 Soundsystem - How to move LFE only to the Subwoofer?
Solution 1:
There is an option for lfe-crossover-freq=
in pulse-daemon.conf
.
Here's what man pulse-daemon.conf
says about it:
lfe-crossover-freq= The crossover frequency (in Hz) for the LFE filter. Set it to 0 to
disable the LFE filter. Defaults to 0.
Instead of altering the settings under /etc/
, I'd recommend that you copy these files to your user's home folder. (If you've already changed them, copy from your backup of the original files):
cp /etc/pulse/daemon.conf ~/.config/pulse/daemon.conf
cp /etc/pulse/default.pa ~/.config/pulse/default.pa
Add 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,lfe
Add (or uncomment) the following lines in ~/.config/pulse/daemon.conf
:
remixing-produce-lfe = yes
remixing-consume-lfe = yes
lfe-crossover-freq = value
Replace value
with the desired crossover frequency (in Hz). Frequencies below this value will be sent to the LFE channel.
Restart pulse with pulseaudio -k
