Okay, found it. So, to enable the subwoofer for non-subwoofer source material (such as a stereo source), you need to set enable-lfe-remixing = yes in /etc/pulse/daemon.conf
And the fact that LFE remixing was suddenly enabled by switching profiles was a bug, sent a patch here: http://lists.freedesktop.org/archives/pulseaudio-discuss/2014-February/020122.html -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1040873 Title: [N56VZ, Realtek ALC663, Black Headphone Out, Right] No sound at all: Subwoofer not working To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/1040873/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
