LFE (sub-woofer) disabled in Ubuntu 10.10 Maveric Meerkat

When I updated to ubuntu 10.10, I had this mysterious problem.

The sub-woofer just worked one time right after I clicked the "5.1 System" in the ubuntu sound options. As soon as a song ended, the sub-woofer was mute again.

I expected this to be an issue of the pulseaudio integration in 10.10. The reason was way simpler!

In 10.10 by default:

enable-lfe-remixing = no

is set in

/etc/pulse/daemon.conf

Just change this to

enable-lfe-remixing = yes

and pulseaudio will mix the 2 channel sound tracks up to the 5 channels including LFE!
