Hi David, thanks for your reply. I have installed the latest alsa DKMS for my machine : oem-audio-hda-daily-lts-saucy-dkms_0.201402051426~ubuntu12.04.1_all.deb on ubuntu 12.04 with saucy LTS enablement stack.
I also add your recommended section in /usr/share/pulseaudio/alsa-mixer /profile-sets/default.conf and extra-hdmi.conf. This made pulse audio crash: I attached a syslog so you can see full log. You will find things like that: pulseaudio[2048]: [pulseaudio] alsa-mixer.c: Assertion 'eb = p2->elements' failed at modules/alsa/alsa-mixer.c:3191, function path_set_condense(). Aborting. pulseaudio[2043]: [pulseaudio] main.c: Daemon startup failed. Any idea ? ** Attachment added: "syslog with oem-audio-hda-daily-lts-saucy-dkms_0.201402051426~ubuntu12.04.1_all.deb" https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/1040873/+attachment/3973792/+files/syslog.test -- 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
