Thanks for your assistance. However, I'm not sure what to do with this information exactly... I'm no expert. As to your question:
"The other output capable pin is node 0x1b, do the driver connected this node to node 0x02 or 0x03?" I checked with HDAAnalyzer, it seems like 0x1b is connected with mixer 0x0c, I can't make out any other connections. I also made sure that pin 0x17 and the nodes you mentioned are not muted. Maybe a screenshot (attached) brings more light into this... ** Attachment added: "Screenshot of HDAAnalyzer with pin 0x17 selected" https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/1553685/+attachment/4597644/+files/Screenshot%20from%202016-03-13%2010-39-36.png -- 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
