So, if you want automatic LFE remixing, that should be possible through PulseAudio:
First, add a new profile for 2.1 by adding this section to /usr/share/pulseaudio/alsa-mixer/profile-sets/default.conf: [Mapping analog-surround-21] # Note that the line below should NOT be changed to surround21. device-strings = surround40:%f channel-map = front-left,front-right,lfe,lfe paths-output = analog-output analog-output-speaker priority = 7 direction = output Second, make sure this line is present in /etc/pulse/daemon.conf: enable-lfe-remixing = yes Then restart pulseaudio (run "pulseaudio -k" in a terminal), then select the new profile in the sound settings. I haven't used LFE remixing myself, so not sure how well it works, but worth a try :-) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/871808 Title: Asus N55SF/N75SF - External subwoofer not working To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/871808/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
