for now best i have acheived is: - pins configured as #2 solution says (first post in this bug report) - in /etc/pulse/daemon.conf you need to enable this option: enable-lfe-remixing = yes
with this option you wont have to change profiles each time song changes to get woofer working - use a 'daemon' from this bug report (post #41) or my little changed ver (it shows 'ubuntus' notifications when plugged etc) this setup 'tries' to play correctly when you provide 5.1 input - try with some movie - credits have some music the woofer tries to play only basses - the problem is that they are not clean and loud - havent figured out why yet. when you provide stereo input it plays left/right channel (all the tonnes) theoretically this option: enable-remixing = yes in /etc/pulse/daemon.conf should fix it (it should do 'low-pass' filter and the woofer should get only basses) but it doesnt work - setting custom channel-map / default-sample-channels helps nothing setting in /etc/pulse/default.pa load-module module-alsa-sink device=hw:0 channels=6 channel_map=here many different channel mappings(same num as channels num) also helps nothing normally when set 5.1 profile - the woffer loudness is affected also by front-left/right volume (the volume sliders in pavucontrol) but when you add to the /etc/pulse/default.pa this line: load-module module-combine channels=3 channel_map=front-left,front-right,lfe you will see in pavucontrol another set of sliders left right woffer put these 5.1 sliders to the eg. 50 / 100% play some music (can be stereo) doesnt matter, in pavucontrol (playback tab) set your music app so it will play to the 'simultaneous output to built-in audio analog surround 5.1' go to output devices tab and now front-left / right doesnt change the volume of the woffer - can mute both and the woffer will just play (you need to use these new added set of sliders (these 3)) - not the default 5.1 sliders prolly its not 'ready' / nice to use but its good for testing - you can hear what your woffer really is playing etc. if someone wants this option - you can add it to the 'daemon' script - so it will load / unload that module when you plug/unplug the speaker (using pacmd or smth.) also be sure to restart pulse every time you change its config files: pulseaudio --kill should do the job (it should autospawn after few secs) if not just use pulseaudio --start (do these as nonroot user) whats left is to force pulseaudio to 'create the basses' on the fly (lowpass filter) - maybe then it wont play left/right channel if someone has any idea how to improve it - feel free i can test ** Attachment added: "wooferDaemon.sh" https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/1040873/+attachment/3875829/+files/wooferDaemon.sh -- 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 ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
