@David Indeed, your trick gave me exatly the same result.
Whatever trick I use (your post #49 or my post #48), there are still some limitations: - When I boot the computer, I have to set the mode to "Analog Stereo Output" first and then back to "Analog Surround 5.1 output" to make the sound work (in the sound settings panel). - When I put the omputer in sleep mode, there is no way to get sound working on resume - When I play with the "output volume" in the sound settings panel, it sometimes make the sound become completely crushed (noisy, high pitch peaks). It may become "normal" again if I continue playing... Let me know how to further investigate ! -- 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 ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
