Hi guys, I was not as lucky as you were... I have an Asus N56VZ laptop on ubuntu 12.04. My subwoofer wasn't working (i could only hear some noise from it).
I tested: 1. Post #8: Setting the pin configuration default to 0x99130112 for pin 0x16 --> No changes. 2. Post #34: edit /etc/modprobe.d/alsa-base.conf and add this line: options snd-hda-intel model=asus-mode4 --> No changes 3. Post #34: I updated to alsa-hda-dkms_0.201207281618~precise1_all.deb in combination with the edited /etc/modprobe.d/alsa-base.conf --> No changes My ALSA-INFO: http://www.alsa- project.org/db/?f=2778e7f430aa95ae219d0b2bc3cb5e46abd0a33a 4. Finally, it seems that my subwoofer is connected to a different PIN. I installed snd-hda-tools: #sudo apt-add-repository ppa:diwic/hda #sudo apt-get update #sudo apt-get install snd-hda-tools #sudo hda-jack-sense-test -a : *** Without subwoofer: Pin 0x1e (Black SPDIF Out): present = No *** With subwoofer: Pin 0x1e (Black SPDIF Out): present = Yes So I retested an adapted post #8: #sudo echo 0x1e 0x99130112 > /sys/class/sound/hwC0D0/user_pin_configs #sudo echo 1 > /sys/class/sound/hwC0D0/reconfig --> it gave me the same result as many of you : subwoofer worked but seems to be plugged with right channel... --> I set the mode to "Analog Surround 5.1 output" in the sound settings panel and now it seems to work perfectly... I uninstalled alsa-hda-dkms_0.201207281618~precise1_all.deb and it still worked. I removed options snd-hda-intel model=asus-mode4 in /etc/modprobe.d/alsa-base.conf and it stopped work. Finally, on a fresh install, to make your subwoofer work on Asus N56VZ, you would have to: a. Add to rc.local : echo 0x1e 0x99130112 > /sys/class/sound/hwC0D0/user_pin_configs echo 1 > /sys/class/sound/hwC0D0/reconfig b. Add options snd-hda-intel model=asus-mode4 in /etc/modprobe.d/alsa-base.conf c. Reboot d. Set the mode to "Analog Surround 5.1 output" in the sound settings panel --> Can you fix it in order to make it work more easily for users ? -- 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
