I'm having the same problem on Ubuntu 18.04.1 and Lenovo Y700-15isk. Tried to assign unconnected pins 0x17 and 0x1b to LFE with hdajackretask with no success. Power-state on D0 instead of D3 with hda-verb.
Unmuted every node related to those pins, and put high volumes on every channel with alsa/pulseaudio. I'm out of ideas. I can offer USD100 as bounty if someone can help solve this problem. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1553685 Title: Lenovo Y700-17ISK subwoofer doesn't work To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/1553685/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
