If you add options snd-hda-intel model=inv-dmic option to /etc/modprobe.d/alsa-base.conf, works.
There seems to be a problem with this laptop. I never needed to add that option to get the headphone jack to work. But on bug https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/1224099 a user reported that using that option in Ubuntu 14.04 LTS fixed the problem. But as I said, I didn't need it before. Whatever changes do to the kernel, they broke something in the driver. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1670394 Title: [Satellite Pro P200, Realtek ALC268, Black Headphone Out, Front] No sound at all To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/1670394/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
